ventilator and stovepipe opening is another very desirable one, 
always provided in Government tents. This opening usually is 
placed directly below the ridge at the left of the entrance. It meas- 
ures 6 inches in breath and 8 inches in length, and is covered by a 
lapel secured on the inner side. 
Tents may be screened effectively by hangings of five-mesh English 
bobbinet around the sides and over all openings, or by means of gal- 
vanized-wire screen sections inserted as indicated in Plate VIII, 
figure 1. 
For winter use tents should be floored at least 12 inches above the 
ground. 
Tables 14 and 15 show the common sizes of wall tents, their dimen- 
sions and approximate costs when made of the various grades of 
material, and also the maximum permissible number of occupants 
for each size. The prices given are list prices for 1915, include poles 
and stakes, and are subject to a discount of from 35 to 50 per cent. 
Table 16 shows the dimensions of a number of sizes of stable tents 
and gives the prices of each of the sizes made of the various grades 
of duck. The prices are approximate list prices of 1915, and are 
subject to from 35 to 50 per cent discount, but they are for complete 
tents, including tops, sides, and all necessary poles and stakes. For 
the top, poles, and stakes, but without sides the fist prices run from 
65 to 75 per cent of those given in the table.
