The idea of the inventor is to so construct a car that it will not burn up and will not go to pieces in a collision. a The New Steamer Teutonic. The White Star Company’s new steamer Teutonic proves to be very fast, but she did not quite equal the speed of the City of New York, which started on the trip out from England at the same time. The Teutonic is a new type of steamer. She is the first merchant ship built in compli- ance with the conditions of the British Admiralty, so that in case of emergency she may be used as a war-ship. The vessel has twin screws, and was built at Belfast by Messrs. Harland & Wolff for Messrs. Ismay, Imrie & Co., of the White Star Cylinders.

In accordance with the Admiralty re- quirements, all the machinery has been placed below the water-line. The boilers are 12 in number. Some are 12 feet and some are 12 feet 6 inches in diameter and 17 feet long, with six furnaces in each and a grate area of 1163 feet. The twin pro- pellers, which are 21 feet 6 inches in diam- eter with a pitch of 28 feet 6 inches and a superficial area of 128 feet, are especially interesting on account of the unusual man- ner in which they are placed. They over- lap each other to the extent of 5 feet 6 inches; or, in other words, they each ex- tend over the central line 2 feet 9 inches. ' AN 7 = SS SS .

The vessel, notwithstanding her great size, may from the peculiarity of her con- struction be considered as one of the safest ships afloat. The whole of the ma- chinery, engines, boilers and coal for work- ing either of her twin screws is shut off completely from its neighbor by a fore- and-aft bulkhead, which intersects the six | largest of the 12 water-tight compart- ments. This fore-and-aft bulkhead is pierced by only one locked door, the key of which is held by the chief engineer. The doors between the engine-rooms and the The Teutonic carries only two masts and three funnels. The poles, however, carry no yards, as it is believed her engines are strong enough to propel her in any weather without the aid of square sails. LT Our Consular Service.—The necessity for seeking a higher standard in the char- acter of our foreign consular offices is broadly hinted at by a prominent mer- chant of this city, D. A. De Lima, in a letter to the New York Board of Trade and Transportation. He says: ‘‘ The fact is notorious that we deem our relations with our neighbors of the South of so little importance that we have, with very rare exceptions, always sent men to represent us who, though perhaps capable for other things, have been entirely unqualified to till their positions, The majority of them are men who before their appointment have never been interested in the South American States; they have been entirely ignorant of their history; the previous re- lations with the United States; they know August 22, 1889 _THE IRON” AGE, 275 nothing of the trade, and in consequence | will that can ong endure.

Se The Law and the Trusts. Deprecating the predictions of a portion | of the public press that trusts will be sum- marily ended by violent methods at the hands of the people, the Philadelphia Ledger Aiscusses the question very sensibly as follows: Trusts and combines, whenever and wherever they exist for the purpose of re- stricting the output of any necessary of living—of anything needful to the well- being of society—in order to fix upon it an arbitrary and artificial price, become op- pressors and as such are to be got rid of.

The length of the frame is 7 feet 2 inches, the width 15 inches and the hight from the track to the top of the bed 21 inches. The wheels are 18 inches in diameter, have a 38-inch tread, and are shrunk on the axle. The axle is formed of 2,%,-inch round steel, each spindle being prov ided with 12 rollers 4 inch in diameter and 44 inches long, which construction constitutes an anti-friction bearing, per- mitting the car to be easily moved even when heavily loaded. The construction of the bearing is shown in the upper view. The weight of the car complete is 1000 pounds. ‘These cars are made by the Jacob Hoffman Wagon Company, of Cleveland, Ohio. — The new French twin-screw steamer La Touraine, in course of construction for the American trade, will be faster and larger than any of her predecessors. She will be of 8000 tons burden, or 1000 tons larger than the Bourgogne, Bretagne, Gascogne and Champagne, while her horse-power will be increased from 8000, as in the older boats, to 12,000. She will be provided with twin screws and with the triple-expansion engine of the type which was first introduced on Atlantic lines by the French line.

The latter, (Editorial Corre sponde nce.) attention of American Bessemer men. In the rolling-mill proper the first object of interest was a 60-inch reversing blooming- train, rolling slabs with two edging passes, with tables on both sides and a vertical hydraulic shear. Near it is a 36-inch slabbing-train. A somewhat pe- culiar practice was observed. The loco- motive which brought the 4-ton slab to the train after depositing it backed up a few rods, and then starting forward liter- ally bucked it into the rolls, a proceeding which was repeated whenever the slab made its appearance on that side of the train. On the other side was a roller-table mounted on a track, servi.g alternately the slabbing-train and theadjoining plate- train, the power being transmitted by a square shaft running the entire length of the trains in front of the housings. On this side of the train the plate is forced into the rolls by means of a vertical pusher-bar. In both trains the rolls are worked by an hydraulic cylinder and rack engaging with the screw. By the side ofthis train was a 36-inch plate-mill. The whole of the finishing side of the two trains is com- manded by an overhead traveling-crane, which carries the plate to the great shear. The latter, the largest in the world, is a very interesting and massive piece of ma- chinery, weighing 289 tons and having a capacity to cut cold 3-inch-plates 10 feet long. One wrinkle noticed in connection with the plate-roiling was the use, already alluded to in The lron Age, of a series of gas-jets playing on the rolls to keep them hot while the train is not rolling. All the steel used in making plates is now made in the open-hearth furnace plant of the company, there being four in a line cast- ing into one long pit.

The greater number of these subsides has _ been claimed by railway companies. The Do- minion Government has contributed alto- gether to railways in bonuses $134, 278, 219, or nearly one-half of the public debt. A large proportion of this has gone to subsi- dize the Canadian Pacific Railway, on which the Government has expended altogether over $61,000,000. There has also been extended to railways, in the shape of loans, assistance to the extent of $20,920,035. Provincial governments have aided railways to the extent of $23,342,758, and municipalities have given them $13,044,224. When the Dominion was formed in 1867 there were in operation 2258 miles of rail- way, and on June 30, 1888, there were 12,163 miles running and a total of 12,701 completed. was $160,471,190, and in 1888, $727,180, - 449. Exclusive of Government aid the sources of capital are: Ordinary share capital, $231,623,891, preference do., $95,870,491; bonded debt, $228,617,728, about 25 per cent. of the total capital being State and municipal aid. The train mileage has increased from 17,680,168 in 1875 to 37,391,206 in 1888, the number of passengers earried from 5,190,416 to 11,- 416,791, the tons of freight hauled from 5,670,836 to 17,173,759, the earnings from $19,470,539 to $42,151,153, the working expenses from 15,775,532 to $30,652,048. The mileage of the several railway com- panies in Canada alone stood as follows last year: Canadian Pacific system, 4562 miles; Grand Trunk system, 3093 miles; Dominion Government, 1184; New Bruns- wick system, 4154; Canada Southern, 3624; Southeastern system (in the Prov- ince of Quebec, under control of the Can- adian Pacific), 2604; Manitoba and North- western, 207 miles, in addition to a large number of smaller roads. The Northern and Northwestern, in Manitoba, had, in 1887, 493 miles of road; mileage for 1888 is not given. The proportion of expenses to receipts was as follows: Canadian Pa- cific, 71; Grand Trunk, 69; Canada Southern, 61; New Brunswick system, 67; Canada Atlantic, 57; Government railways, 114. The proportion for all Canadian railways was 72. IMPORTS AND EXPORTS. The imports of Canada have risen from $73,459,644 in 1868 to $110,894,630 in | 1888.

CANADIAN SHIPPING. The shipping owned in Canada on De- | cember 31, 1888, was as follows: Steamers, | 1285, with gross tonnage, 207,142, and 7142 sailing vessels, the total net tonnage being 1,089,642. During 1888 there was a de- | |crease of 36 sailing vessels, 40,605 tons, and an increase of 45 steamers, 28,953 tons. The tonnage of vessels remains about the | same as in 1873, although in the interval | —in 1878—it rose to 1,333,015 tons. The | |three maritime provinces—particularly New Brunswick and Nova Scotia—own the bulk of the shipping, viz.: New Brunswick, 239,332 tons, Nova Scotia, | 1 485,709 tons. Quebec Province comes next with 178,520 tons, then Ontario, 139,- | |tons, British Columbia, 14,249 tons, Man- jitoba, 5,744 tons. At $30 per ton the lvalue of Canadian shipping would be | $32,689, 260. 264 vessels, 25,130 tons. The number of vessels arriving at and departing from all Canadian ports in 1888 was 64,303, of 15,217,308 tons register, an increase of 6368 vessels and 1,126,310 tons over 1887. Men employed numbered 640,911, or 51,- 1/115 more than in 1887. Over one-half was Canadian, and most of the remainder foreign.

A — Steamship Subsidies. As the question of subsidies in aid of steamship navigation is likely to have a prominent place in the discussions of the next Congress, it is well that the public should know what the Government has done heretofore in this direction. In 1845 the Postmaster-General was autho- rized to contract for ocean service in steamers whenever the public interest re- quired it, and he was left to decide upon the routes and ports of the several lines. He contracted with Edward Mills for four ships and 20 trips a year from New York to Bremen and Havre for $400,000, and with E. K. Collins & Co. for four ships and 20 trips from New York to Liverpool for $385,000. Contracts were also made for service from New York to New Orleans and the Isthmus of Panama and from Panama to California and Ore- gon for $489,000. Congress approved the contracts and advanced part of the money upon them to assist in building the ships. In 1850 a line was established from Charles ton to Havana under a payment of $50,000 ayear. The subsidy to Collins was in- creased in 1852 to $858,000 a vear. In that year the Government was expending #1,840,250 in subsidies, as follows: To Liverpool, $858,000; from New York to Charleston, Havana and New Orleans, | $290,000; for the Panama and Oregon | service, $348,250; to Bremen and Havre, $294,000; between Charleston and Havana, $50,000. In 1853 the opposition to sub- sidies became serious. In 1856 the subsidy | to Collins was reduced to $385,000, and in |the following year his contract was | allowed to come to an end; the Bremen ‘and Havre contracts expired at the same |time. No further subsidies were granted until 1865, when one of the $500,000 was given to the Pacific Mail Company for carrying mails to China and Japan, and another toa New York company to carry mails from New York to Brazil for $150, - 1000. Both of these contracts were termi- | nated at the end of ten years.

The capacity of the works is 100,000 pouncs per annum, to produce which requires not only that at least 400,- 000 pounds of sodium, 800,000 pounds of chlorine and 1,000,000 pounds of double chloride should be annually manufactured, but in addition that each of these mate- rials should be produced at a very low cost, in order to enable the metal to be sold at 20/ per pound. The company’s works now cover a space of nearly 5 acres. They are divided into five separate de- partments—(1) sodium, (2) chlorine, (3) chloride, (4) aluminium, (5) foundry, roll- ing, wire-mills, &e. In each department an accurate account is kept of the produc- tion each day, the amount of material used, the different furnaces and apparatus in operation, &c. In this manner it has been found possible to ascertain each day exactly how the different are progressing and what effect any modifica- tion has, either on cost, quantity or qual- ity of product. By this means a complhi- cated chemical process reduced to a series of very simple operations. so that, while the processes are apparently compli- cated and difficult to carry out success- fully, this is not the case now that the details connected with the manufacture have been perfected, and each operation carried on quite independently until the tinal materials are brought together forthe production of the aluminium. is pre CeSSeS is MANUFACTURE OF SODIUM, The first improvement occurs in the manufacture of sodium by what is known as the Castner process. Practically, the proc- ess consists in heating fused caustic soda in contact with carbon while the former sub- stance 1s ina perfectly liquid condition. By the process in vogue before the intro- duction of this method it always deemed necessary that special means should be taken to guard against actual fusion of the mixed charges, which, if it were to take place, would to a large extent allow thealkali and reducing material to rate. Thus having an infusible charge to heat, requiring the employment of a very high temperature for i was sepa- Its decomposition, the iron vessels must be of small cireum- ference to allow the penetration of the heat to the center of the charge without actually melting the vessel in which the materials are heated. By the new proc- ess, owing to the alkali being in a fused or perfectly liquid condition in contact rectly with carbon, the necessity of this is avoided, and consequently the reduction can be carried on in large vessels at 2 Com- paratively low temperature. The reaction taking place may be expressed as follows: 3NaHO + C Na.CO, + 3H + Na.

Directly below each aperture in the bottom of the furnace are situated the hydraulic lifts, attached to the top of which are the platforms, upon which are placed the crucibles to be raised into the furnace. Attached to the hydraulic lifts are the usual reversing-valves for lowering or raising, and the platform is of such a size as, when raised, completely to fill the bottom aperture of the furnace. The charged crucible, being placed upon the platform, is raised into its position, the edges meeting those of the cover, forming an air-tight joint, which prevents the escape of gas and vapor from the vessel during re duction, except by the hollow arm pro- vided for this purpose. The natural ex- pansion of the iron is accommo- dated by the water-pressure in the hy- draulic lifts, so that the joint of the cover and crucible not disturbed until it intended to lower the lift for the purpose of removing the crucible. The length of time required for the first operation of reduction and distillation is about two hours. <At the end of this time the crucibles are lowered, taken from the platforms by a large pair of tongs on wheels, carried to a dumping-pit and thrown on their sie The residue is cleaned out and the hot pot, being again gripped by the tongs, is taken back to the furnace.
