On the summit of Mount Whitney during a storm of sleet at 12.30 p. in. July 

 •26 the air was 29°; at 9.30 a. m. July 28, when-the sky was clear, it was 39.5'-. 



The largest tributary of_ the Kern River is the Little Kern. This stream 

 empties into the Kern far helow the region of our investigations. Its headwateis, 

 however, were examined by us and temperatures noted at the points given in tabh^ 

 VI. "Its sources lie in deep canyons just west of the Great Western Divide and south 

 of Farewell Gap. As seen by the table, these upper sources of the Little Kern in 

 temperature correspond closely with the tributaries of the upper Kern (main stream) 

 east of the Divide.

At Broder's cabin on Little Kern the air was 51' at 9.15 p. m. July IT and 53 

 at 5.30 a. m. July IS. The temperature of the water in Soda Creek. 1 mile below 

 Quinns Hor.se Camp, at lo a. m. July 16, was 51°. 



In leaving Threerivers for the Mount AVhitney region our trail lay along the 

 South Fork of the Kaweah River from near its mouth to its highest sources. This 

 gave opportunity for taking temperatures along almost the whole course of this 

 stream. These records, as given in table vii, show that in the middle of July tlie 

 temperature ranges from the high point of 70°, near its mouth, to the low temper- 

 ature of -13°, taken at Camp No. 3, South Meadow, not far from the sources of the 

 river, the temperature falling as the elevation increases. During the latter part of 

 the summer the lower portions of the stream no doubt show a still higher degree.
