In regard to the floor lights, they do not appear in the list of contents of the boxes, but they are not essential to the lighting of the lens, and it can be done without them, temporarily covering the holes.

Enquiries will be made at once in regard to them, and if not found, they will be supplied. You are requested to inform the Board at once in regard to them.

Very respectfully,
George H. Elliot
Major of Engineers, U.S.A.
