caught off base in newly filled earth where
it will be easy to dig him out.
Made up a dozen of these sticks by
remodeling the ones from last year.
Early this A.M. returned to and W of
Tobolew on the Swaw Ranch where I
have done so much of my work on
previous years. The ground was perfect
for digging - from the rains of last
week in Palm. Bran grass not over
2" high. One [illegible] limiting factor for
the use of the electric stick is that
in order to keep an eye on them
they must be set in a limited area
where they all can be watched
from one spot. And they should
not be over 4 miles apart for
when a light comes on one
has to get there fast. Put out
10 sticks in an area of about
125 yds. in diam and had them
all set by 11 A.M. As usual, the
main activity started between 3:30 PM
& 5 P.M. One drawback developed in that
sometimes the snow formed a new
mound at side of trigger & covered it
from top so it failed to light.
