Ernie WED. No sign of the Yosemite Road - other than the tadpoles - at Porcupine Flat between the hours of 10 A.M.-2 P.M. and 6:30 P.M.-9 P.M. on Wednesday. The weather was cloudy & looked like rain. Caught a "water snake" and some yellow- legged frogs (2) which later escaped via the untied top of my bag, Thamnophis THURS. No sign of the Yosemite Road at Jamsrock Flat or on Jamsrock Creek up to the highway. (Came) left to Souloume Meadows. Plenty of good looking food area, however. There are two loops - meadows - that look particularly favorable on the trail between Jamsrock Flat and Hetch- Hetchy (on the south side of the road.) One loop is 108 yds. S. on the trail (S. of the road) and the other is a quarter of a mile S. on the trail. Saw another "water snake" in the 2nd loop, and caught these 3 poor yellow- legged creatures in the 2 loops. The whole creek looks good - for fishing as well as for trails. Saw a clutch of 5 eggs of the Sierra junco - on the ground. Noticed a junco flying at some object on the ground, and investigated. It was this snake gorging himself on a fledgling (looked so that it had just hatched - no feathers,
