1 As there was no warehouse at the textile school, the cotton was stored in the textile building. 
In each, case the cotton was stored for several months prior to the 
time the tests were begun — at Fall River in a cotton warehouse, 
which was not heated; at West Raleigh in the textile-school building, 
which was heated until warm weather. The weather at Fall River 
was cold and damp, with considerable snow on the ground at the 
time the warehouse weights were obtained. The textile-school tests 
were in progress at West Raleigh during the summer, the tempera- 
ture was high, and, as the cotton proceeded through the manufactur- 
ing processes, practically no loss of moisture was evident. 
Table IX shows in brief the average temperature, relative humidity, 
and the percentage of moisture in the cotton while in the warehouse, 
picker room, and card room, both at the mill and at the textile school.
