Es wurden keine Tests durchgeführt, aber das Athermometer an einem Maitag zeigte 27 Grad Unterschiede zwischen dem Wasser im Speicherturm und dem Indie-Netz, bevor es durch den Kondensator ging. In dieser Grube befinden sich auch ein Cochrane 1,250 h. p. Speisewassererhitzer und ein 24-Zoll-Ölabscheider. Auch eine Wasserpumpe von 104 Gallonen pro Minute Kapazität.

Tests have not been made, but athermometer on a May day showed 27 degrees differ-ence between the water in the storage tower and that indie mains before passing through the condenser. In thispit are also located a Cochrane 1, 250 h. p. feed waterheater and a 24-in. oil separator. Also a feed waterpump of 104 gallons per minute capacity.

Any machine having arevolving spindle can be used with this bar. Theprinciple upon which the tool works is that of a taperslide upon which the tool holder moves. As the barmoves the tool holder moves by means of a screw andnut, and fed by a star wheel coming in contact witha trip dog fastened to the machine.

MODERN Virgil would no doubt sing of A man and machines, instead of men and arms, and although Russia has a vast army and ispreparing to take military issue with Japan, the conflict for supremacy among modern na-tions will be decided by their machine shops.The rule is—the more machinery the lessmen. I have been through a large flour millfrom top to bottom, machinery all going andno man to be found. Railroad shops are industries of adifferent class, obviously requiring many men because theproduct does not admit of a continuous process; butwithin my observation locomotive works for substantiallythe same product have reduced need of men about 3 to 1.We now consider, however, a class of machines inwhich large capacity was realized at an early stage ofthe history—punches and shears. Any gains in capacityhave been made in attachments for feeding the work, andthese are not applied to ordinary punches and shears..Automatic devices displacing human attendan
