On Feb. 1, 1938 I caught 13 gophers on a
5 acre alfalfa field one mile south east of
Fernley, Nevada There were numerous mounds
on this field and I believed I caught about
40% of all the gophers on this field.

Twenty percent of the females taken
were pregnant. The soil in this section
of the country (Fernley) is a coarse,
rocky soil in most places. Small rocks are to
be found in any of the soil. This differs
considerably from the sandy and adobe soil
of Fallon, Nevada district.
