Murray 1948 137 Journal June 30 10 mi SE Mesquit, 400 ± ft, Baja Calif. mounds but found it very difficult to find the holes as they were plugged up for quite a distance. Set 1 trap. We are finding it necessary to conserve water stringently, since we are far from any source. Dr. Benson sent word that they might be back by July 4, and we can't last much longer without doing something. Shot 1 jackrabbit in the afternoon. I have now seen several and also several brush rabbits. The latter seem to prefer the wash, and the jacks the flat ground. Set 50 live traps, 25 on the flat and 25 in the wash on the very soft sand just beyond the first gully. We have been interested in finding any differences in habitat preference between merianae and agilis. So far nothing points to any. Put out 6 Schuylers, 3 of them in front of nests which are just holes in the bank along this side of the wash. There are a number of them there, some with stick pile additions on the outside. The other three traps are in front of houses in cactaceae. Slightly warmer today and with less wind.
