DEPRECIATION OF PORTABLE BUILDINGS. 
It is impossible to forecast at this time what will be the life of the 
buildings. On July 10, 6 months after they were put into service, 
there was no noticeable depreciation. After their transfer to the 
new site, when they were more than 10 months old, the actual 
observable damage and loss amounted to less than 14 per cent of 
their value; it may be said safely that the total depreciation during 
the first year amounted to no more than 5 per cent. Itis to be ex- 
pected that this rate will increase each year during the economic life 
of the buildings, but what this rate will be can not be predicted. 
From present indications it seems entirely possible that their life 
may be as long as 8 years, but this figure probably is too great to 
use as a basis for estimating the economy of the buildings. It has 
been assumed for this purpose that the rate of depreciation will 
increase each year by an increment of 5 per cent, beginning with 5
