I set out 80 traps, mainly around clumps of Juncus sp.?, I wore hip boots while setting the traps as the marsh was very wet and muddy underfoot. It rained lightly most of the afternoon. After setting out the traps we returned to the Martin Ranch where we unloaded and prepared to spend the night in the bunkhouse. 7:30 to 8:30 p.m. we helped with the chores in the milk barn. 8:30 p.m. we returned to bunkhouse, wrote general notes.
