tion will be introduced, in that each grade will be used to spin the size 
of yarn for which it is best adapted, so that when the entire series 
of experiments is completed the results will present as many sided a 
view of the question as possible. 
Approximately two bales of each grade have been bleached in the 
raw and the same number of yarn made from each bleach at Danville. 
With the exception of one bale of western Good Ordinary no diffi- 
culty was encountered in bleaching. 
About 25 pounds of waste, or as much thereof as is produced on the 
different machines for the respective grades, have been marked 
and sent to Washington, where waste types will be prepared for the 
determination of value. For careful examination, as well as for exhi- 
bition purposes, the following types of waste have been collected from 
each of the 10 tests: 
About 25 pounds of opener and breaker lapper motes. 
About 25 pounds of intermediate lapper motes. 
About 25 pounds of finisher. 
About 25 pounds of card strappings. 
About 25 pounds of card toppings. 
About 25 pounds of card flyings and motes. 
A record of the white waste made in spinning the respective grades 
has also been made, as well as the scavenger and clearer waste. 
Hygrometers have been placed in the various mill rooms and read- 
ings made hourly. A relative humidity of about 55° for the picker 
and card rooms and 65° for the spinning room has been maintained 
so far as practicable. 
NATURE OF THE COTTON SECURED FOR THE EXPERIMENTS. 
No serious difficulty was encountered in securing in the month of 
June, 1913, sufficient cotton for both of these tests. It was, of 
course, necessary, considering the nature of the experiment, that 
each bale of cotton be of very uniform character and exactly of the 
specified grade. It was not deemed wise to accept a lot of 10 or 12 
bales which would merely average the specified grade. No bale was 
accepted- unless, when the bands were removed and the bale opened 
up and sampled in 12 different places, it proved to be of very uniform 
character. Purchasing cotton in this way is a very different matter 
from purchasing an average lot for ordinary mill purposes, where 
considerable latitude can be allowed so long as the average of the 
purchase is about on grade. Nevertheless, as before stated, no very 
great difficulty Was encountered. In Low Middling Atlantic States 
Upland cotton it was necessary to accept a few bales of a slightly 
bluish cast, differing to a small extent in color from the box types of 
the official grades. Samples drawn from the accepted bales have 
been inspected by dozens of well-known experts from all parts of the
