TEST CYLINDERS FOR THE LIBERTY ENGINE AT THE PLANT OF NORDYKE & MARMON, INDIANAPOLIS, IND.

CRANK-SHAFT DIE FOR THE LIBERTY ENGINE. BUICK ENGINE CO., DETROIT.

ACCEPTED LIBERTY ENGINES BEING BOXED FOR SHIPMENT.

It was evident that in the actual production of the Liberty engine there would continually arise practical questions of manufacturing policy that might entail modifications of the manufacturing methods, while our aviation authorities in Europe could be expected to advance suggestions from time to time that might need to be embodied in the mechanism. Consequently it was necessary to create a permanent development and standardization administration for the Liberty engine. Nor could this supervision be located in Washington, because of the extreme need for haste, but it must exist in the vicinity of the plants doing the manufacturing.
