Design. Design and office work in connection with the dry-dock coaling plants, and floating cranes has been in immediate charge Civil Engineer F. H. Cooke, United States Navy, with a force engineers, draftsmen, and assistants numbering 18 at the end the fiscal year.

Coaling plants. As stated in the last annual report, proposa under circular 763 were opened in the Washington office June 14 1913, and were received on the Isthmus for canvass just prior to th close of the fiscal year 1913. These proposals were accompanied b plans, specifications, and other data. The five proposals receive are listed below:

The circular specified general requirements only, and the proposal were therefore in the nature of competitive designs. Although a least two general arrangements were permitted by the circular for th Cristobal plant, all the submitted designs were based on the sam general layout, this consisting essentially of a pier structure inclosin the coal pile, the long sides of the pier being parallel to each othe and affording support for the unloading, stocking and reclaiming, and reloading units, deep water being provided on two sides and at on end of the pier structure. At Balboa, circular 763 admitted propo sals on two general designs, one known as "N," based on the provi sion of entirely new machinery throughout, the other known as "O," based on the utilization of the four berm cranes which were used fo mixing and placing concrete at the Pedro Miguel and Miraflore Locks. There were 19 items listed in the circular whereby the worl might be subdivided if advantageous; but for convenience as a gen eral indication of the prices received, the bids for Cristobal only, for Balboa plan "N" only, and for both complete are shown above. Bu

e bidder, Augustus Smith, submitted a proposal under plan "O," bid being $570,000 for this design, time of completion, both plants, th plan "O" Balboa, 34 months. The storage capacities of the ants as contemplated by circular 763 were as shown in the following

The general plans accompanying circular 763 permitted enlargeents of both plants.
