BEHAVIOR OF SEED COTTON IN FARM STORAGE. 



17 



per cent, while the interior of the looser and untramped contained 10 

 per cent. The surface cotton of the two piles by this date, December 

 1, had run down to 8.7 per cent on the tramped and 8.8 per cent of 

 moisture on the untramped pile. As far as can be observed, there 

 were no correlations between moisture and temperature in these two 

 lots of cotton. 



A bale of the staple, which is about 1 J inches long, from the tramped 

 pUe was purchased for spinning and waste comparisons with freshly 

 picked and immediately ginned cotton of the same variety, namely, 

 Webber, and with another bale ginned from a body of 40,000 pounds 

 of seed cotton of the same variety which had been stored unginned 

 for a considerable period in bin C. 



Fig. 3.— Pile containing about 30,000 pounds of seed cotton. This cotton was picked through a period 

 of several weeks and did not suffer from heating. 



Bins C and D ultimately contained between 70,000 and 80,000 

 pounds of seed cotton. This was accumulated gradually, the cotton 

 at the bottom having received the preliminary drying in the loft, 

 while the later pickings were added to the pile daily, unless rains 

 occurred which made it advisable to dry the early morning pickings 

 of certain days before adding them to the pile. It was found that 

 practically all of the later pickings, if dry when picked, could be thrown 

 into the bulk without any danger of heating. 



About the middle of November, when the pile in bin Chad attained 

 a weight of about 30,000 pounds, two composite samples were taken 

 from both the inside and the outside of the pile. The pile of cotton 

 as it appeared at this time is shown in figure 3.
