10/11/25 48' October 11, 1925 - no rain. I took some large snap rat traps and set them in a tunnel in the Carolina mine at Divisadero and baited them with tankage. I set two traps behind a pile of wood or stakes and had passed for some distance when I heard one of the traps snap. On returning I discovered a (10579) white toed blue rat in my trap. I (10467) caught one of these rats on the small island at Lake Olomega. The natives there claim they are in their houses. These rats must be the Roof rat but I have no description available. October 12, 1925 - No rain. The traps in the mine had two half grown White-toed blue rats. I didn't put them up for both had their skulls broken and the ants had beaten me to them. One was caught under the pile of wood where I caught an adult yesterday and the other was caught by a path or trail along the wall. Some barn owl pellets which I collected yesterday contained many skulls and bones of what I took to be white-toed blue rats and a small Carnivorous mammal probably a weasel. I could smell skunk scent on some of the barn owls that ran shot from these shafts.
