Referring to Table 13 and comparing the percentage of waste 

 obtained from the different types of bales, it is seen that there was 

 practically no difference in the amount of visible waste discarded 

 from the flat, standard, and high-density hales compressed in a dry 

 or normal condition, while the high-density bale compressed in a 

 wet condition was about 2 per cent more wasty. The percentages 

 of visible waste obtained from the different types of bales were as 

 follows: 



Per cent. 



Flat bale 22. 78 



Standard or railroad compressed bale 22. 54 



High-density bale 22.63 



High-density bale compressed wet 24. 20 



MOISTURE CONDITIONS. 



Table 14 gives the average temperatures and relative humidities 

 under which each type of bale was tested.
