8/27/25 of time too late. I found several Oryzomy's nests in thorny bushes covered with vines. Sometimes they were in little thorny trees which were covered with vines. The nests were usually constructed on the outside with leaves or other coarse material while the inside was lined with fine dry grass. I shot several mice with my 22 shot pistol by poking the nest with a stick and shooting the mice as they came out. Being suddenly aroused from their nap the mice usually come out of their nest and stop rather dazzled, and are easily shot. August 28, 1925 - Cool; a nice day to work. No rain. We were in the field this morning before day-break. I lost only one Oryzomus by the ants. In a open space in the mimosa-brush in some heavy stemmed grass I caught another (Sigmodon Hispidus - ) Cotton rat. The smaller specimens that I have been calling wooly mice are very likely immature Sigmodons. Our native assistants saw a deer (Odocoiles) in the low land forest near the San Miguel river; a swampy forest region. August 29, 1925 - Drying wind blowing all day. Many of the mouse traps were sprung this morning. The cause of this is probably (Sigmodon hispidus - ) cotton rats which are too large
