SPINNING TESTS OF COTTON. 
15 
Plate V, Figure 1> is from a photograph of 40 's yarn spun from the 
Delta l|-inch cotton which shows practically no difference in the 
quality of the yarn spun from the different types of bales. 
MANUFACTURING PROPERTIES. 
There was no noticeable difference in the running of the different 
types of bales. 
SUMMARY OF TESTS. 
The results of this test show that compressing cotton does not 
injure its spinning value. 
SPINNING TESTS OF WEBBER 49 COTTON OF 1| INCH STAPLE. 
The Webber 49 cotton was compressed into four bales: A flat bale, 
a standard or railroad compressed bale, a high-density bale, and a 
high-density bale compressed in a wet condition. The latter bale 
was made by wetting a flat bale with water from a hose for a day 
and then compressing it to high density in the usual manner. 
PERCENTAGE OF WASTE. 
Table 13 gives the percentage of visible, invisible, and total waste 
obtained from the different types of bales.
