Plate V, Figure 2, is from a photograph of 50's yam spun from (lie 

 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 diiTcrent 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 w T ere to 

 be run continuously in a mill, special opening equipment would be 

 required.
