484 kellerman: effect of boron on vegetation 



California: Furnace Creek, Death Valley; old abandoned borax 

 claims in the Amargosa Canyon ; colemanite discovered in Tick Canyon, 

 a branch of Soledad Canyon, 40 miles north of the city of Los Angeles, 

 and 5 miles from Lang Station, on the Southern Pacific; Slate Rajge 

 Marsh, San Bernardino; in Inyo County 100 miles north of the Slate 

 Range District; at the mouth of Furnace Creek and Resting Springs 

 in Death Valley ; Mono Lake ; Owens Lake ; Clear Lake ; small quantities 

 in spring at Red Bluff, Tehama County; Tuscan Springs, Tehama 

 County, 8 miles east of Red Bluff; near the mouth of the Pitt River; 

 40 miles north of the Tuscan Springs several similar localities too small 

 to be of any practical importance; a reconnaissance of the "coast range" 

 of mountains, from the neighborhood of Shasta over a length of some 30 

 miles towards the South brought to light borates in the numerous small 

 springs abounding in that locality but only in minute quantities; other 

 localities between Clear Lake and Napa City; in Siegler Valley there 

 is a hot spring containing borate of strontia and other borate salts; 

 a borate spring in Suisan Valley; Kern County, 10 miles from Kalienti; 

 20 miles west of San Bernardino ulexite occurs in the Cane Spring 

 District; Lake Elsinore, Riverside County. 



Nevada: Ulexite occurs abundantly in the Arizona Desert, and 

 near Wadsworth, Nevada; on the eastern slope of the Sierra Nevada, 

 near Walker's Pass, borax is found; also in Panamint and Death Valley 

 in Lower Nevada; borax found in Esmeralda County in Fish Lake 

 Valley, Clayton Valley, Big Smoky Valley (locally known as the San 

 Antonio Marsh, in the Silver Peak Quadrangle), Teels Marsh, Rhodes 

 Marsh, Fish Lake Pond; at Sand Springs in Churchill County, 100 

 miles from Columbus Marsh; Hot Springs, 50 miles farther to the north- 

 west; mud lakes in the western part of the State, one in the vicinity 

 of Ragtown, Churchill County; in Humboldt, Land, Whitepine and 

 Lincoln Counties there are beds of salt containing borax. 



Oregon: Curry County; Harney County, extending over 10,000 

 acres south of Lake Algord. 



Wyoming: Salts in Union Pacific Lakes, called Big Lake, Track 

 Lake, and Red Lake, vary from 1V2 parts per thousand to ^l\ part 

 per thousand of borax. 



In addition to these localities, I have personally collected small 

 samples in the alkali spots in Kern County, Calif., where plants 

 were either dying or completely absent. Borax percentages of
