Set about 15 mow traps in the grass. There are also thin patches of raspberry. The rest took up the Horse Sinto trail about 300 yards. Here found a somewhat marshy patch where a slight stream flow crossed the path. There was a very dense corylus californica and green growth of [illegible], raspberry, and green grass, with a little Equisetum. Put a few traps here and then a little way down the trail found another patch of thick green grass, raspberry, Corylus and lush green herbs. Placed the rest here. At dusk, Dr. Pearson and I went down and waited at the Willow Creek Hotel, where bats were reputed to emerge from a crack in the roof. They wouldn't come out for us, however. there were an ample number of large bats flying in the area, with a few small ones. Large looked like Eptesicus.
