HYDROCYAXIC-ACID GAS FUMIGATION" IN CALIFORNIA. 
The number of strips in each section can now be readily calculated. The 21 strips 
should be numbered on the diagram from left to right. Section A requires six strips 
and 8.5 inches of the seventh. Similarly, section C requires six strips beginning at 
the right (twenty-first to sixteenth, inclusive) and 8.5 inches of the fifteenth. Sec- 
tion B requires the remaining 20 inches of strip No. 7, 20 inches of strip No. 15, and 
seven entire widths, thus making the total of 21 strips required. 
The cutting of the cloth can be done without waste if the details of construction 
are well planned. In the above tent seven strips 50 feet long (49 feet 10^ inches) 
should first be cut out for section B. Strips Nos. 7 and 15 are next cut and the out- 
side corners cut at an angle of 45 degrees, as indicated in the diagram. Each strip 
for sections A and C is cut shorter by its own width outside at each end than the strip 
preceding it. Thus the 
required lengths of the 
side strips are found by 
matching the inner edge 
of the new one to the 
outer edge of the one be- 
fore it. It is desirable to 
have the central section, 
B, made up entirely of 
full-length strips so that 
the stress will not be 
across seams. The stress 
is so slight, compara- 
tively, in the side sec- 
tions A and C that this is 
not an important point. 
Such is the con- 
struction of a 50-foot 
tent. The method of 
constructing a tent 
of any other size is 
similar. Tents up to 
45-foot "feize are con- 
structed throughout 
of either of the drills 
or of 8-ounce duck. 
Fig. 2. — Plan for construction of octagonal sheet tent 50 feet across, 
showing lines used in constructing octagon: A, C, side sections; B, 
central section of full-length strips; E, E, so-called "ends" of tent; 
S, S, so-called "sides" of tent; R, R, reinforcements; 1-21, strips 
of duck 29i inches wide overlapped J an inch at the seams. (From 
Morrill.) 
Larger size tents should have the full length strips of 8-ounce duck, 
while the shorter side strips, or "skirts," as they are sometimes 
called, are made of a light drill. The main strain and wear falls on 
the middle, heavier and stouter, long strips; hence the use of the 
lighter material for the "skirts" decreases the weight of the tent 
without affecting its durability. The duck used in such tents should 
be of the very tightest grade available, while the 6J-ounce or 7-ounce 
special drill previously recommended is most suitable for the "skirts." 
Amount of cloth required for different-sized tents. — It is very essential 
in constructing tents to know the amount of cloth required for the 
size which it is intended to make. The writer has calculated this for 
the regular sizes and gives below the results. Calculations are based
