per cent the first year. According to this assumption, which cer-

purposes of cost computation.

111 determining the per-capita per-day cost of the quarters it has 
been considered that the entire cost of erecting the quarters and 
loading and hauling them should be charged off in the period of 311 
days during which the camp occupied its first site, and a proportional 
amount has been allowed for the 183 days up to July 10. With this 
procedure in mind it is believed that the per-capita costs per day 
given in Table 5 will require no further explanation.
