In the afternoon the sky became overcast, and at six p.m. rain
actually began to fall heavily, but only for a quarter of an hour,
though it continued to drip for two or three hours. During and after
that we had heavy thunder and most vivid lightnings. The thermometer

MONDAY, 24TH NOVEMBER.

We had thunder, lightnings, and sprinklings of rain again during last
night. We made another departure for the Shoeing Camp and Elder's
Creek. At the bare rock previously mentioned, which was sixteen miles
en route 30 degrees north of west, we found the rain had left

thunder and lightnings and five minutes' rain came.

From here I steered to the one-bucket tank, and at one place actually
