The latter material, which is usually classed among the ductile and workable things, is, nevertheless, not so tough of tensile strength as to be an easy proposition for the in- experienced to use for press-drawn purposes. It is freely manipulated by the workmen at this fac- tory and ferrules and “cups” of all shapes and sizes are drawn. The promoters and present management of the company held executive positions for years in the production of similar lines of manufacturing, and the plans for the buildings, the working out of the site possibilities and the methods employed in factory output were based on prior study. A. S. Lyhne is president of the company and H. K. Beach is secretary-treasurer. To take care of expansion a single story extension, a part of the first floor of a four-story building, has a roof which is prac tically the weather-protected floor of another story vet to come. Furthermore, the site is laid out with a complete plan for manufacturing and other buildings to cover its entire area.

There is every likelihood that the idea and its clothing will fit each other until the full resources of the site are exhausted. These are the easier of de velopment because of the free access obtained by the factory to the surrounding streets. Whatever the development may be of the manufacturing or ganization, there is ready approach for all team ing, and the main tracks of the New York, New Haven & Hartford Railroad trunk line being near by provide excellent shipping facilities. Adja cent to the neighborhood is the water front of Bridgeport, providing a footing for transporta tion facilities up and down the storm-sheltered Long Island Sound and out upon the Atlantic Ocean. + The general course of factory operations is for the incoming materials to enter on the ground floor and there to be fed to the heavier machines and thence travel upward for lighter operations, being finally inspected and pat ked on the top story. Offices are on the second floor, as this gives all necessar) privacy and yet permits the use of the largest possible windows of clear plate- glass. A second floor office also allows free access to the several manufacturing departments with a minimum of stair climbing.

As Sweden exported far more iron than she has consumed at home, thousands of 1 in that country are wholly or partly unemp! becoming turbulent, and strikes are frequent minor trades. The fact that Sweden made mort out of the war conditions relatively than any country, and that it possesses abundance of money, matters because the gains have gone into pockets already well lined. Prices saries and rates of wages rose more in Sweder the war than in Great Britain, and while the remain high opportunities to earn wages ha largely reduced. The present threatening toward the employing and official workers is the result to some extent of disgu the former for their active sympathy with G in its brutal attempt to dominate Europe. “The stocks in the hands of the British Go referred to above consist of 80.000 tons of Swe as well as 15,000 tons of Swedish bar iron, m latter being such as is used for making the ties of crucible t I x makes worse, classes steel.” Scrapping German Submarines WASHINGTON, May 6.-— marines have a breakup value of about $12,00 ing to an interesting report sent by Vice-' “Scrapped” Ger nard F.
