Mice (1270 at C?) are still not over 20 grams
and bad mold pattern down middle of back,
Aug. 22 at 5 p.m. set rows A, C, E, H, J, & K of Tilden grid
(Sources from Mineral Springs). Lots of white
mice in wine. Skunks; oatmeal bait. While I was
setting, a Park Ranger came along with a lot of
poisoned grain. He was putting handfuls at the
bottom of each young Sequoia tree. Some of the trees nicely girdled above the metal collar around the
trunk. Weather cool clear. 60 traps.
Aug. 23
Row traps 8-9 a.m. Cool, clear some dew.
Row A 5 mice, 2 min. 0 Rethro
Row C 3 " 0 " 2 Rethro
Row E 2 " 1 " 1 "
Row H 2 " 2 " 3 "
Row J 3 " 4 " 2 "
Row K 1 " 1 " 5 "
\frac{16}{16} \quad \frac{10}{10} \quad \frac{13}{13} = 39 mice.
Only 1 of the mice (a mouse) was a tagged one. Tagged it
released the mouse & Rethro, released mice without tagging so all mice were adult. Clear traps,
at 6 p.m. set rows B, D, F, H, I, J, & K
= 70 traps.
Aug. 24 at 8 a.m. (light dew, some dew, moon almost
full):
Row B 3 mice, 2 min. and 1 Rethro.
Row D 3 " 2 " 2 "
Row E 3 " 2 " 2 "
