The whole neighbourhood of Mount Saint Helena is full of sulphur and of boiling springs. The Geysers are famous; they were the great health resort of the Indians before the coming of the whites. Lake County is dotted with spas; Hot Springs and White Sulphur Springs are the names of two stations on the Napa Valley railroad; and Calistoga itself seems to repose on a mere film above a boiling, subterranean lake. At one end of the hotel enclosure are the springs from which it takes its name, hot enough to scald a child seriously while I was there. At the other end, the tenant of a cottage sank a well, and there also the water came up boiling. It keeps this end of the valley as warm as a toast. I have gone across to the hotel a little after five in the morning, when a sea fog from the Pacific was hanging thick and gray, and dark and dirty overhead, and found the thermometer had been up before me, and had already climbed among the nineties; and in the stress of the day it was sometimes too hot to move about.
