season, or the months of April, May, and June. Table 2 shows the 
precipitation by months and the total annual precipitation at Moro, 
Lind, and Nephi. The records at Moro are for the years 1905 to 
1920, inclusive; at Lind, for the years 1916 to 1920, inclusive; and 
at Nephi for the years 1898 to 1920, inclusive. In this connection 
it should be borne in mind that the precipitation at Lind during 
this period is much below normal. In the 9-year period from 1897 
to 1906, inclusive, the average precipitation at Lind was 11.8 inches 
as compared with 7.22 inches in the period of these experiments.

During the period of the experiments Nephi had the highest annual 
precipitation and Lind the lowest. More of the precipitation at 
Nephi was in the form of snow, although there was always some 
snow at Moro and at Lind. In case of a sudden thaw with frozen 
soil, a part of the winter precipitation at Moro and Lind sometimes 
is lost as run-off on account of the rolling topography of the land.
