THE DRYING OF BEETS PULLED, TOPPED, AND LEFT IN RATHER SMALL PILES. 



On the morning of October 17, 1912, four other rows of beets were 

 dug, pulled, and topped as rapidly as possible. The tops and beets

 ground), referred to in Tables HI and II, respectively. 



were weighed separately. The beets were thrown into small open 

 piles (fig. 2) according to a common practice among beet growers, 

 and the tops from the four rov/s were laid in a single windrow. At 

 intervals the beets and tops were weighed. The mean temperature 

 during this experiment was 50° F. (See fig. 1.) This exporimenrt 

 was repeated on the following day. The loss in weight of beets and 

 tops together was 5.19 per cent. The mean temperature during this 

 ex|)erim(!nt was 62° F. (See fig. 1.) The results are shown in 

 Tabki II.
