On these occasions six rows of beets were used, the tops from the 
six rows being thrown into one windrow. Since they were more 
thickly piled, 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 PDLES 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.
