G. Ellendt & Co., of New C. E. Turrell having direct contractor was Mr. Hans Hilton, ofWhite Plains, N. Y., who designed theforms and skillfully executed the work ascalled for in the specifications and of the excellence of the designand execution of the work, is the fact thatwhen the props were removed from the. Fig. 3.—V:ew Showing Mixing Plant and Concrete Hoist. A fairly wet concrete was used, and thetamping was done with a tamper madeof 2x4 in. scantling. The forms were of 1-in. and 2-in. boardswith battens, and the props, wereof 4x6-in. sticks. Very few nails wereused where thev would interfere with easyremoval of the forms. The forms on thesides of the large girders were strippedtwo weeks after pouring the concrete, butthe bottom forms and props were left inplace for six weeks. Concrete was mixed with a Ransomemixer. The raw materials and the mixedconcrete were conveyed in Ransome two-wheeled push carts. These carts provedsuperior to ordinary wheelbarrows, notonly because of the larger loads conveyed,but because the materials could be ac-curately measured in the carts. The specifications provided that the ce-ment should be delivered either in strong To ft. girders their deflection was so smallas to be almost infinitesimal. We are in-formed that the d
