80 GENERAL CONSIDERATION OF NAVY YARD DESIGN. 



is believed to be the best for wharfage space, convenience of operation and gen- 

 eral efficiency. The placing of the dry-docks at the outer end prevents their inter- 

 fering with the yard transportation. Additional docks can and should be added if 

 this yard is to take care of the whole fleet. The docks shown in the plan may be 

 entered at either end and each has a middle caisson which has several seats so that 

 the dock may be divided into two single docks of variable length. 



The Building Ways offer nothing particularly new. The estimates given are 

 for the utilization of the old ways (those in the present yard) as far as possible. If 

 not too expensive a double gantry crane instead of the present cantilever might be 

 desirable. The plate yards are covered with railway tracks on a system that 

 should cheapen the handling of material. 



The Outer Row of Shops. — The shops of the outer row on each side of the 

 yard are of one story only and are 120 feet wide exclusive of any slight additions 

 to the floor space made by the lean-tos such as would be desirable in foundries. All 

 shops are reached by standard gauge railway tracks (single dot and dash line) ; 

 while the shops where heavy weights are handled are reached by the sixty-ton- 

 crane track (double broken line). The positions of the tracks are only approxi- 

 mate and further study on a larger scale might change a number ; some additions 

 should doubtless be made. All curves are of 125 feet radius. 



The Inner Rozvs of Shops. — These shops are on the lower floors of two-story 

 buildings. They are eighty feet wide and are all reached by standard gauge rail- 

 ways. 



The Storehouses. — The second floor of all the inner rows of shop buildings 

 forms the general storehouse for all active stores, except those of very great weight 

 or those which are supplied onl}'^ to ships and are not used in any process of yard 

 work. The ends of these buildings are connected by covered bridges and at the 

 east and west ends a covered structure supports and covers a track connecting the 

 north row of storehouses with the south row. This gives a continuous track. On 

 this track it is intended to run trolley trains (always in one direction) for distribu- 

 ting stores and transportation of people — particularly of foremen and leading men 

 who are inspecting stores desired for use, and of men sent to the storehouse for cer- 

 tain articles urgently needed. It will be noted that this continuous railway track 

 (with two full-length sidings in each building) will reduce enormously the cost of 

 handling, the time of delivery, and the convenience of examination. When desir- 

 able to do so, railway cars would be hoisted on the elevators in the receiving store 

 or lumber store and run to the place where their contents would be stored. Stores 

 for the inner row of shops are lowered through small elevators directly to the spot 

 desired. Stores from the outer shops are lowered on cars which can be brought 

 alongside or inside the outer shops. 



The Buildings of the Central Rozv are only 60 feet wide. On the ground floor 

 there are miscellaneous storerooms, the electrical school, yard restaurant, etc. On 

 the second floor are all the yard offices, the Commandant and central correspond- 

 ence and planning office in the approximate center, the other offices grouped around
