BULLETIN 1135, U. S. DEPARTMENT OF AGRICULTURE. 
Plate V, Figure 2, is from a photograph of 50 's yarn spun from the 
Webber 49, 1^ 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 any of the 
bales.

Fig. 4.— Irregularity of 50's yarn spun from Webber 49 cotton compressed to different densities. 
SUMMARY OF TESTS. 
The results of this test show that compressing cotton in a dry or 
normal condition does not injure its spinning value.* 
Compressed cotton to high density while wet increased the waste 
approximately 2 per cent, but did not materially affect the breaking 
strength. 
CONCLUSIONS. 
All of these tests showed that compressing cotton to standard or 
high density when in a dry or normal condition is not injurious to 
its spinning value. 
Compressing wet cotton to high density either increases the per- 
centage of waste or reduces the breaking strength of the yarn, or may 
do both. 
Compressing cotton into a round bale with a hard core reduces 
the strength of the yarn about 7 per cent. If the round bale were to 
be run continuously in a mill, special opening equipment would be 
required.
