MOISTURE DETERMINATIONS. 
At both the mill and the textile school, samples of the cotton were 
selected for moisture tests from each place in the processes of manu- 
facture where the stock was weighed. These samples were placed in 
air-tight cans, weighed carefully on equal arm balances sensitive to 
0.05 grams, shipped to Washington, reweighed in the same manner, 
and then tested in the cotton-testing laboratory for moisture content. 
Table VIII gives the results of these tests.
