On these occasions six rows of beets were used, the tops from the 

 six rows being thjown into one windrow. Since they were more 

 thickly pUed, naturally the evaporation was less than in the preceding 

 experiment, in which beets were exposed only during the morning 

 hours, before the maximum temperature had been reached. 



THE DRYING OF BEETS PULLED, TOPPED, AND LEFT IN PILES OF MEDIUM SIZE. 



On the morning of October 17, 1912, several other rows of beets 

 were dug, topped, and thrown into two piles of medium size after 

 being weighed. (See fig. 2.) These were weighed at intervals, with 

 the results shown in Table III. The mean temperature during this 

 experiment was 43.25° F. (See fig. 1.) 



A similar experiment was carried out by Dr. C. O. Townsend, at 

 Garden City, Kans. This was begun on November 10, 1912. These 

 results also are shown in Table III.
