Excerpt from Power Consumption Tests of a Bascule Bridge Through, the hearty co-operation of the Bureau of Engineering, Division of Bridges, of the City of Chicago, and the Facility of the Armour Institute of Techlogy, tests on the operation of a modern bascule bridge, as outlined in the following paper, were made possible and carried to a successful conclusion. The writers wish to express their sincerest thanks to Mr. John C. Bley and Mr. C. F. Harrington of the Division of Bridges for their untiring interest and practical help, grid to Professor John C. Penn of the Amour Institute faculty for his valuable assistance and co-operation. It is hoped that this will only mark the beginning of a series of tests, which in time will complete the solution of the problems involved, and which will help in the perfecting of numerous small details tending to bring about more efficient bridge operation.
