A machine for digging trenches, canals and railroad cuts which is the first of its kind, and is believed to be the largest of any kind for the purpose ever built, was recently shipped to North Africa by the Van Buren En- gineering Company, New York City. Others of generally the same kind are to be built for use in this country, particularly in the Western States for excavating irri- gation canals. The machine is the invention of the gen- big. and is operated by a crew of three, an operator, a helper und a fireman. <At a single passing of the machine a cut 6% ft. wide of any depth up to 5 ft. can be made. Wider and deeper cuts are made by successive passes of the machine. It is adapted for heavy dry excavating in almost any kind of material except, of course, solid ro¢k. When an uncommonly large boulder is encountered which is too large for the machine to handle it must be Vide ae ths tas ned he Views of Both Sides of the 78-In.

Van Buren, and was constructed from his designs and under his supervision by the Bergen Point Iron Works, Bayonne, N. J. Figs. 1, 2 and 38 are general views of the complete machine, and the remainder of the illustrations give details of its construction, and illustrate its manner of operation. The machine is self-propelling and runs directly on the ground, that is. it does not require rails such as are used for a steam shovel. It is declared to have a ¢a- pacity e’ avout six times thar of the largest steam shovel, Isosened or blasted, and unless the pieces are too large they can be removed from the trench by the machine. icxcessively large boulders would otherwise have to be removed by block and tackle or similar means. Briefly, the machine consists of a heavy frame carry- ing the cutting wheel, driving machinery and power | lant, and supported by three wheels, two main traction wheels 2t the rear and a forward steering wheel. There is also carried at one side what is known as a leveling wheel, which is used to right the machine if it gets i * = THE 10560 Fig. 3.—A Front End View of the Excavator slightly out of a perpendicular position. This wheel is supported at the outer end of an One wheel suffices for keepiag the machine in an upright position, as the weight of the outrigger with that of the water tank which it carries will hold the leveling wheel adjustable outrigger. in contact with the side of the trench.

Deposited on this conveyor the spoil is moved to one side passes center of or another and delivered to either cars or wagons, or on the ground at the side of the cut. All of the control of the machine is from the operator’s platform at about the center of the machine. The two main driving wheels are 8 ft. diameter by 2 ft. face and with mud and if picks, such as are used on road rollers to prevent slip- ping on the ground.

For the faster drive the power transmission is from the engine shaft to the gear a, and intermediate gear and the main traction thence through the differential gear shown in Fig. 5 to the internal gear on the inside of each traction wheel rim. The gear 0b carries bevel pinions with their axes radial to the gear bB which mesh bevel gears each in one piece with a brake drum which per- mits either wheel to faster than the other when turning curves. Band brakes around the drums ce Fig 5 enable holding one or the other to compel the machine to turn in a shorter space. Applying both simultaneously is the means of quickly stopping the machine’s headway. For the slower speed the clutch a Fig 4 is thrown to en- gage an otherwise loose sprocket wheel d, the drive is then by chain to the clutch shaft e, thence through spur gears and another sprocket chain to the gear f which, through an intermediate, drives the main traction gear b as before, but at a-slower speed.

It is unnecessary to the intent of the present descrip- tion to go into the manner of connecting the controlling levers with all of the various movements. Figs. 4 and 5 show in a general way the connections to the clutches, brakes, &c. The function cf the various levers are set forth in Fig 5. The cutting wheel is 13 ft. 8 in. in diameter and car- ries the buckets or shovels which do the digging. The buckets, ten in number, are each the whole width of the wheel, and between them on each side are side flaring blades which increase the width of the cut sufficient to clear the driving gears on the cutting wheel. The buckets are armed with manganese steel points. Exclusive of the coal box in the rear of the machine the overall length is 48 ft. The width of the frame is 7 ft., and the leveling wheel when in horizontal position THE IRON AGE 1057 extends i2 ft. out to one side. The height from the ground to the level of the operator’s platform is 14 fi When taking its maximum depth of cut, 5 ft., the nia chine moves forward in ordinary soil at the rate ot about 10 ft. a minute. When cutting to a depth of only 1 ft. the machine can be speeded up to as fast as 50 fi. per min., and for intermediate cutting depths inter mediate speeds are used, the ratio being such that the capacity of the machine at any depth of cut is about 325 cu. ft. of material per minute. The machine weighs all told upward of 50 tons. ~~ +e Among the many projects for the development of municipal water supply now in progress throughout the West involving notable engineering features is that of the city of Santa Barbara, Cal.

The Vollrath Tham, Which Carries Its Own Unloading Plant. A new type of ore carrier, the Vollrath Tham, of the Lulea & Ofoten Steamship Company of Stockholm, Swe den, arrived recently at Philadelphia, Pa., on her maiden voyage across the Atlantic Ocean, with 7614 tons of Kirunavara iron ore, from Narvik, Norway, consigned to the Reading Iron Company, Reading, Pa. This vessel was designed particularly for carrying ore from Scan dinavian to other ports which are without extensive facilities for unloading. Particularly of interest, there- 3ssV0 cu. ft.

The the hoppers are of the in- verted V type and do not extend the full depth of the hold, permitting of ready discharge of the ore at the bottom through suitable chutes. At the loading ports the ore is discharged into the separate the ore The ore bottom of Stern View of the Vollrath Tham at the Loading Port, Narvik, Norway.

Hawthorn Leslie & Co., Ltd., Newcastle-on-Tyne, England. It is of all steel construction, 376 ft. long be- tween perpendiculars, 564% ft. broad and has a depth of 3314 ft. It is driven by triple expansion engines of 2000 hp. and has a cargo capacity of 8400 tons. The eargo space is divided into seven hoppers or bins, three of which measure 24 x 32 ft. and four 12 x 32 ft., all approximately 30 ft. deep, giving a total capacity of 161.- View Showing Discharging Hatches, Ore Bin and Chutes, and Ore Bucket at the Chute, bins, as shown in Fig. 1, by means of chutes, directly from the ore cars. An illustrated description of the steel ore dock at Narvik was given in The /ron Age y 9, 1908. At the unloading ports the ore is de- livered through the discharge chutes, 34 ft. wide, of which there are four to each bin, into steel tubs or buck- ets, as shown in Fig. 2. These buckets are 4 ft. 4 in. by 5 ft. by 15 in. high, and each has a maximum capacity of 2% tons. They are lifted by electric jib cranes, five on each side of the vessel, located on the deck and on the center the discharging hatches, and are January lines of October 7, 1909 swung over the side of the vessel and discharged as in Fig. 3. The cranes are of the built-up type, the length of the jibs being 20 ft. A complete circle can be swung with the cranes, operating on a roller bearing base, with watertight caps. The motors and drums for operating the cranes are located in separate hoist rooms, below the deck and directly under the cranes. <A 5-hp. motor is used for the slewing, while a 20-hp. motor furnishes the hoisting power. The manipulation of the crane is by a single lever, through controller boxes located on the platform of the crane, on which the operator stands and which extends over the hatchways, enabling the operator to have a full view of buckets. lowering of the foot the operation of hoisting or The latter operation is controlled by a Fig. 3.—The Forward Port Electric Cranes Extending Outboard, Unloading Into a Lighter at Rotterdam.

Siemens erators supply the necessary current for the operation of the motors. The buckets are of fixed type, and for convenience in moving have four rollers affixed to the bottom. The dis- charge of the buckets is controlled by a wire rope at- tached to the rear of the bucket, which passes over a drum and is held taught by a counterweight operating on small wheels, running .up or down the inside of the crane jib. When the buckets have been lowered to the desired position this rope is held fixed by a hand brake operating on the drum, the bucket, then being slightly lowered, tips at an angle and permits of the complete discharge of the ore. The operation of the gates on the discharge chutes at the bottom of the bins is extremely simple, but most effective. The main gate is 3 ft. 10 in. wide and ap- proximately 18 in. high, strengthened by heavy flat bar ribs which also form the hinge joints holding them by four flat bars to hinge joints on the bins. One of the lower bars extends to a length of 7% ft., is counter- weighted and serves as a hand lever by which the gates are raised and lowered. This gate alone, as shown in Fig. 2, was found insufficient to make a clean shut off of the ore and a supplementary gate, in shape of an angle iron, 4 in. wide, was added at the bottom lip of the dis- charge chute and operated by a separate lever. The two gates, in conjunction, form a complete and perfect shut off, practically no ore whatever dropping after the bucket has been drawn away from the chute. The discharging capacity of the vessel is rated, from practical tests, at 4400 tons per 10-hour day. Twenty men are required for the operation, two to serve the buckets in each of the five discharging hatches and one each to operate the cranes. At the Port Richmond wharves, however, where the vessel was docked when the view given in Fig. 4 was taken, unloading was much slower, as it was possible to discharge from one side only. Under such circumstances one crane serves to unload from all of the discharge chutes in each unloading hatchway. No stevedores are requiréd for the discharging of the cargo, the ore being dropped from the buckets either into lighters or into cars on tracks at the vessel’s side. When out of service the cranes are swung inboard, as in Fig. 5, and in ordinary weather remain stationary. For safety, however, each pair of cranes is lashed together at the tops of the jib. gen- The Pullman Company, which is building large shops at Pullman, Ill, for the construction of steel passenger cars, has placed an order with the Allis-Chalmers Com- pany, Milwaukee, Wis., for the power plant equipment, consisting of two steam turbines and generators aggre- gating 5,000 hp., with condensers, exciters, &c. auxiliary to them. The Glacier Metal Company, Richmond, Va., expects shortly to manufacture a new fibrous metallic packing, under the title of Silver metallic packing, the special fea- ture of which is its ability to stand superheat. 1060 THE IRON AGE The Le Blond Heavy Duty Automobile Lathe. Manufacturers having large quantities of duplicate lathe work have little use for numerous attachments on their machine tools. For this reason the R. K. Le Blond Machine Tool Company, Cincinnati, Ohio, is offering its new heavy duty lathes (illustrated and described in Thi lron Age, September 2, 1909) in a simplified form known as the heavy duty automobile lathe. This tool is built in 16, 18 and 20 in. swing, the 20 in. size being shown in The headstock retains the same features as on the October 7, 1909 casting as previously described. The lead screw and half nuts are left off. This apron may be furnished with automatic stops for the cross and longitudinal feeds, of a construction similar to that the company has been using on its high speed roughing lathes for several years. Figs. 2 and 8 illustrate a special equipment of unusual interest applied to one of these lathes in the 20 in. size, and serve to illustrate the usefulness of this design for manufacturing purposes. The equipment is designed for turning the wrist pins on four-throw automobile crankshafts after the journals have been turned. It consists of a special chuck, tailstock fixture, double tool carriage with stops and an automatic stop mechanism on the apron. Fig. 1—A 20-in. Heavy Duty Automobile Engine Lathe Built by the R. K. Le Blond Machine Tool Company, Cincinnati, Ohio. oe aN oe a we ee ee ee Fig. 2.—One of These Lathes Specially machine referred to, with ‘the exception of the back gearing. Instead of the double friction back gear with its quick changes, which are so essential in a general purpose too!, the double back gears are engaged with a sliding key operated hy the hand lever directly in front of the driving cone. The usual quick change box is replaced by a four- change feed hox. The changes are obtained by sliding gears operated by the crank handle shown on the front of the box, and may be made while the machine is in operation under th® heaviest cut. These four changes are doubled by a reversille compound gear on the end of the bed which gives the operator a choice of eight geared feeds, covering a carefully selected range. The apron is double walled of a single box section Equipped for Turning Crankshafts The crankshaft is held in the chuck by one of the turned end journals in a split bearing, and is driven by the V shaped jaw which is screwed down on the first erank arm. This jaw pivots at its back end and is fitted with a helical spring under the clamping screw to facili- tate chucking. This work-holding fixture is carried on a scraped slide on the face plate to,which it is attached by a clamp and an adjustable gib. It is accurately posi- tioned for the two crank centers ly a hardened steel locking pin entering hardened steel bushings in the face plate, after which it may be securely locked in position by the two tee bolts. A counterweight is provided on the back of the face plate which is fitted with stops for its two positions, thus enabling the operator to counter- balance the crank in either position practically instan- October 7, 1g09 taneously. The other end of the crankshaft is clamped at the turned journal in a split bearing in the tailstock fixture. ‘This fixture carries two hardened and ground bushings spaced the exact center distance of the crank throws, which are alternately used as journals on the special tail spindle. The tailstock carries, immediately in front of the spindle, an auxiliary spindle which is spaced the same distance apart as the journals in the fixture. This auxil- iary spindle may be readily withdrawn by the lever shown on the tailstock and serves a double purpose. In addition to affording a convenient means for changing the tail spindle from one hearing to the other it provides a means for accurately locating the tail fixture with rela tion to the crank throws when chucking. The alignment of the crank is readily accomplished by the auxiliary spindle just described and a locking pin shown directly under the crank (Fig. 8) which enters a bushing in the headstock. The carriage is clearly shown in Fig. 3.

Meetings of the American Society of Mechanical En gineers are to be held during the month of October as follows: In New York, on the evening of October 12, in the Lngineering Societies Building, with a paper by Prof. Rk. C. Carpenter of Cornell University on “ The High- Pressure Fire System of New York City.” In St. Louis, jointly with the Engineers’ Club of St. Louis, on the evening of October 16, when Professor Cuar- penter will again present his paper upon the high-pres- sure fire system, In Boston, on the evening of October 20, jointly with the Boston Society of Civil Engineers in Chipman Hall, a paper will be presented by Prof. Gaetano Lanza and Lawrence S, Smith on “Comparison of Results Obtained SE er em Fig. 3 \ Detail of the Work-Holding Fixtures and Carriage of the Specially Equipped Lathe blocks are cast in one piece on a long slide which is mounted directly on the carriage. The rear tool block carries two tools, set the proper distance apart for turn- ing out the fillets, while the front block carries a round nose tool for removing the stock between the fillets. The movement of these tools is controlled by the stops shown on the slide, which enables the operator to duplicate diameters. The longitudinal feed of the apron is controlled by the multiple stop Lar shown on the front of the bed in Fig. 3. The notches in this har, which are spaced the same dis- tance apart as the throws on the crank, engage a stop lever on the apron. In operation the carriage is run up against these stops. which brings the back tools into exact position for turning out the fillets. The carriage is then returned, the front tool run in and the automatic feed engaged. When the stop lever strikes the notch on the bar it operates a clutch on the feed rod and automati- cally throws out the feed. For crankshaft work the stop bar is made as shown to reduce the setting up time. When this feature is applied to a regular automobile lathe the stops are made independent so that they may be set at any desired point within the range of the carriage travel. This construc- tion affords a convenient method of turning shafts with a number of shoulders, and it is claimed that on many classes of work produces more work than the more com- by the Use of Three Theories of the Distribution of the Stresses in Reinforced Concrete Beams,” with the experi- inental results.

It has been for some time quietly rumored in machinery circles that a Chicago concern had in eontemplation the establishment of a plant for the manufacture of machine tools, which would form an important addition to this industry. It is now understood that Joseph T. Ryerson & Son are planning to enter this field and to this end are negotiating for a suitable plant site. Cincinnati is one of the points under consideration, and it is reported that he advantages of location in that city are being investi- gated with a view to the erection there of a large ma- chine tool factory. The company is already well known as a manufacturer and distributer of boiler shop, rail- road shop, fabricating and other iron working tools, and the carrying out of the plan suggested would make it an important factor in machine tools, especially of the heavy types required in railroad and other large shops. 1062 drives are ex- ceedingly heavy momentary overloads, severe shocks and vibration, abnormally rapid acceleration, application of Characteristic of steel mill machinery power at several points remote from one another, and certain operations that necessitate a reversal when run- ning at full speed. Reliability of service is absolutely es- sential, as the various processes form a practically con- tinuous train of operations and a breakdown stops the whole train. This condition makes it imperative that re- placement of damaged parts be made in the shortest pos- THE IRON AGE October 7, 1909 outline dimensions and are interchangeable for the same foundations. The standard alternating current known as MI motors, are designed for 220 and 440 volt, three-phase, 25-cycle current, and are furnished in sizes of from 3 to 150 hp. inclusive. These motors are totally horizontally split magnet frames of octagonal shape, the two halves being held together by a large bolt at each of the four corners. They are sup- ported by four large feet, each foot drilled for one founda- tion bolt. Two bails are cast on the upper half of the frame for handling the motor. Each frame has a large opening over the collector which affords quick and easy brushes and collector rings. There are other openings which provide additional facilities for in- specting the motor. All fitted with mal- leable iron covers held in place by lock bolts so designed motors, inclosed in steel access to the openings are that the covers may he quickly removed. The snost notewerthy feature of this line of motors is the construction by which the stator winding is entirely separate from the frame, resembling in this respect the field coils of a direct current motor. This construction, together with a horizontally split frame, permits of re- placing the rotor or stator very quickly and renders it necessary to keep in stock only spares of the parts most liable to damage. Fig. 1 illustrates the manner in which the upper half of the frame is removed and the rotor, stator and bearings lifted out as a unit for inspection or repairs. In making replacements it is not necessary to make any disconnections inside of the motor frame. The construction is perhaps best shown in Fig. 2, where a slightly different type of motor is shown com- An M I Alternating Current Mill Motor Made by the General Electric Company, Schenectady, N. Y., Showing the Manner of Removing the Rotor and Stator from the Frame as a Unit. The electric drive has several features which adapt it to mill work. Its advantages are, simplicity of power distribution, easy and rapid replace- ment of parts, low cost of inspection and maintenance, flexibility of controlling mechanism and adaptability to automatic control. It only remains to properly design motors, mechanically and electrically, to meet the severe nature of the power demands and to allow for the un- favorable conditions of high room temperature and dust laden atmosphere. The General Electric Company, Schenectady, N. Y., manufactures a complete line of both alternating and direct current motors of especially rugged design for this most exacting class of service. sible time. especially The corresponding sizes of direct and alternating current machines have. the same pletely taken apart. The stator is in the form of a hol- low cylinder and is a unit entirely separate from the frame. The punchings are assembled on steel studs which pass through end flanges by which the punchings are clamped tightly Each half of the frame has several ribs extending lengthwise which are bored to the diameter of the stator and are equal in length to the dis tance between its end flanges. When the stator is low- ered into the frame and the upper half of the frame bolted on, these ribs automatically center it and prevent end motion. Rotation of the stator is prevented by ears projecting from the core. End flanges are provided and insure complete protection to the end windings and permit handling the apparatus freely without damaging the windings. The stator coils are form wound, molded to together.

They are assembled in open slots and are held in place by non- combustible wedges. This construction makes it possible to replace a coil very easily and quickly. The rotor is built up on a heavy spider, the punchings being assembled between end flanges keyed into place under heavy hydraulic pressure. The rotors are bar wound, in all sizes except the 3 and 7 hp., in partially inclosed slots. In order that reversal may be accom- plished in the shortest possible time and with a mini- mum loss of energy while accelerating, the diameter of the rotor has been reduced to a minimum. The collector spider is carried on an extension of the rotor spider to which it is keyed, making it unnnecessary to disturb any connections to replace the shaft. The col- lector rings are bolted to this spider making their re- moval very simple. The rings are of exceptional size and the collector throughout is ruggedly built. The brush holder studs are of steel, are exceptionally large and are screwed to the frame. Heavy coiled phosphor bronze springs maintain practically uniform tension over their entire working range and permit a large amount of wear of the brushes. The bearings are exceptionally large, affording ample bearing surface. The armature bearing housings are a part of the frame castings. The bearings are furnished for either oil ring lubrication or waste lubrication. To change from one form of lubrication to the other it is necessary to change only the upper half of the lining. The two halves of the lining are bolted together and a wrought iron bail is cast in the upper half, providing an easy means of handling the armature, as shown in Fig. 1. The armature end thrust is transmitted directly to the frame by a shoulder in the bearing lining. The countershaft brackets are cast with the lower half of the frame and are heavily ribbed. The caps are bolted to the brackets. The linings for the smaller stand- ard countershaft diameters are cast iron babbited, and for the large standard diameters are malleable iron bab- bited. ‘The countershaft bearings are supplied for waste lubrication. Where motors are geared it is an advan- tage to use, where possible, a countershaft passing through brackets on the motor frame, to prevent the gear and pinion from springing apart under heavy loads. The rotor shafts are exceptionally heavy and have pinion extensions at both ends. They can be replaced without disturbing connections. The pinions are of ham- mered steel and the gears of cast steel. can be used at either end of the motor and are bolted to webs on the lower housing of the armature bearing and countershaft bracket. In order to adapt this type of motor to crane service the 3, 7, 12 and 20 hp. motors have been designed to per- mit replacing the rotor in either of two ways. These ma- chines have circular frame heads at both ends, the frame and frame heads being split. This construction admits of the removal of the rotor by removing the upper half of the frame and lifting it out or removing the head at either end and pulling the rotor out endwise. The heads may be shifted through an angle sufficient to permit mounting the motor on the wall or ceiling. In these sizes the upper half of the frame is hinged to the lower half, the hinge blocks being bolted to the frame to permit of The gear cases their removal if not desired. Fig. 3 shows the individual parts of these motors and brings out clearly the advan- tages in this design. This motor is designed for control by a rheostat in the stationary or rotor circuit. By this means partial speed control can be obtained and the motor can be started and accelerated at practically the same torque per ampere as at full speed. MI motors have a maximum torque of approximately 250 per cent. of rated full load torque, and are designed to carry loads varying instantaneously from maximum in one direction to maximum in the other, with stresses far within the safe limit. They can be stalled momentarily without injury. Although these motors were designed primarily to meet steel mill conditions, they are equally adapted to any service in which the cycle of operation is short and the rate of acceleration and braking high, and where the equipment is subjected to rough handling and forced to its maximum output. ——__.-- The Venice, Cal., High Pressure Salt Water System. That metal conduits will resist, to a high degree, the supposed deleterious effects of contact with salt water was convincingly demonstrated in Venice, Cal., when an extension of a high pressure, salt water system for auxil- iary fire protection, was made recently. The system, which was installed by the Abbot Kinney Company in July, 1905, was the first of its kind to be utilized on the Pacific Coast. It consisted of 12-ft. lengths of 8-in. cast iron mains, 5 in. in thickness, weighing 54 lb. to the foot, to which were attached, at the usual intervals, cast iron laterals 6 and 4 in. in diameter. The system was fed by an intake pipe of 14-in. boiler steel, 3 ft. in diameter, laid in a foundation bed of concrete and projecting 200 ft. into the ocean, supported by concrete piles at the extrem- ity beside the Venice pier. sell and spigot, lead and oakum joints were used throughout, and a pressure of €0 lb. was used on the system, night and day, for more than four years. This was furnished by two underwrit- ers’ pumps having a total capacity of 750 gal. a minute. As the location of the Venice resort is at sea level, no gradient was used in the laying of the mains and lat- erals, which extend throughout the beach town on a level beneath overlying sand varying from 3 to 6 and 8 ft. in depth. A maximum pressure of 250 lb. is possible on the system, and the streams thrown by the 1%-in. nozzles attached to the 2!4-in. standard fire hose used, will read- ily go over the tops of the tallest buildings in the city, which are three stories in hight. Although in constant use for more than four years, Fire Chief G. A. Hubbard of the Kinney Fire Department asserts that not one cent has been expended for repairs since the installation of the system. The high efliciency and low cost of upkeeping the system so impressed the city officials of a neighbor- ing municipality that a month ago the Kinney mains were extended to include a mile and more of frontage along the ocean strand. at the expense of taxpayers. In making the necessary connections, no faults or flaws were found at any point. and the cast iron piping, joints and connections, under a careful scrutiny, appeared to be in as good condition as when first laid in place nearly five years ago. oe a a so ro 7 1064 THE IRON AGE October 7, 1909 A Large Bertsch Combined Multiple Punch 9 punching. and Fig. 2 shows it with the punch crosshead and Squaring Shear. lifted as when used simply for shearing.

So far as statistics go, the figures for imports rather than exports of iron and steel reflect any improvement and it is but slight—that has come to the British iron industry. Exports of iron and steel from Great Britain in August amounted to 351,417 gross tons, against 357,030 tons in August, 1908. The total for the first eight months of this year was 2,830,304 tons, as compared With 2,867,086 tons to September 1, 1998. Rail exports in August were 52,273 tons, against 48,069 tons in August, 1908. For the eight months rail exports were 400,081 tons, against 301,456 tons to September 1, 1908. More than half the increase was in exports to Argentina, while exports to British India and to Portuguese East Africa showed a considerable increase. The exports of galvan- ized sheets were 305,293 tons in the first eight months of this year, against 252,012 tons in the first eight months of 1908. Tin plate exports were 286,951 tons to Septem- ber 1, this year, an increase of 16,000 tons over the same period last year. To the United States tin plate exports were 39,927 tons and 48,891 tons, respectively, in the eight months’ periods of 1909 and 1908. British imports of iron and amounted to 792,477 tons in the first eight months of this year, an in- crease of 89,000 over the figures for the corre- sponding period of last year. The most pronounced in- crease was in imports of blooms, billets and sheet bars, these being 363,082 tons to September 1 of this year, against 319,063 tons to September 1, 1908. ——— +—-o______ steel] tons Driggs-Seabury Plant Improvements.—The Driggs- Seabury Ordnance Corporation, Sharon, Pa., has awarded a third contract for fabricated steel work to the Wm.

WASHINGTON, D. C. October 4, 1800.—Reports are current among the legations here that several foreign governments are preparing to demand for themselves the same tariff concessions from Cuba as are granted to the United States by the existing reciprocity treaty. concessions embrace reductions in the rates of the Cuban tariff ranging from 20 to United States grants a flat reduction of 20 per cent. on all Cuban products. of great benefit to the Cubans, These 10 per cent. Reciprocally, the This reciprocal concession has been who have been enabled thereby to market their sugar and tobacco in this country on very favorable terms. It is claimed, that American manufacturers and exporters have secured little advantage under the and that the Cuban people have spent in European markets the money ob- tained from the sale of their sugar and tobacco in the United States. On this account efforts have been made from time to time to induce the State Department to abrogate the existing treaty, which can be done at any time on six months’ notice, and to negotiate a new con- however, treaty vention more advantageous to American commerce. It is believed that this would have been attempted by Mr. Root, when Secretary of State, but for the revolution which broke out in Cuba, making it necessary for the United States to take over the management of the governinent. Since the restoration of peace in the island the whole tariff problem has been under consideration in the American Congress and no steps have been taken looking to the negotiation of a new treaty.
