GEOLOGICAL SURVEY OF THE TERRITORIES. 161 



The Krahuchen Spring is the one chiefly used for drinking at Ems. 

 This watering-place is stated iu Dr. McPherson's recent work to be the 

 most popular woman's bath in Europe : he adds that this watering-place 

 is well suited for cases of bronchial and laryngeal catarrh. 



From the close correspondence between the Doctor Spring and the 

 Selters Spring, in chemical composition, we can infer that the physiolog- 

 ical effects of these waters will be very similar. Of the far-famed Sel- 

 ters Spring, which sui)plies the world annually with a million and a half 

 bottles of Selters water, Dr. Edwin Lee writes: 'Its action is, in general, 

 cooling, exhilarating, and alterative, improving vitiated secretions of the 

 mucous membranes, giving tone to their glands, and promoting absorp- 

 tion. It may generally be taken without risk by robust and ijletboric 

 individuals, and is of great service in cases of torpor of the vascular 

 and glandular systems, stomach derangement, with acidity and consti- 

 pation, tendency to gout in full habits, and scrofulous complaints. The 

 Selters water would also be serviceable in cases of irritation of the uri- 

 nary organs, or tendency to the formation of stone or gravel in chronic 

 inflammation of the mucous membrane of the bladder.

While my party was engaged at Soda Springs, I obtained some valua- 

 ble information from Mr. Stump, one of the proprietors of the Oneida 

 Salt Works, Idaho, which indicates the existence of some of the most 

 valuable salt-springs on our continent. I was not able to visit them, 

 and these few notes are given here for the purpose of directing the 

 attention of the public to them. They are located in a small side- valley, 

 which opens into Salt Creek, a branch of John Gray's River, about 

 sixty miles northeast of Soda Springs. They are surrounded with high 

 mountains. The little creek iu which the springs are located flows 

 southeast, while the main Salt Creek runs northwest. The water is as 

 cold as ordinary spring-water, and is as clear as crystal, showing how 

 completely the saline matter is held in solution. The market is in 

 Idaho and Montana — mostly iu Montana. The company make 6,000 

 pounds of salt per day, but the supply of water would '^'arrant 25^000 

 pounds per day. There is another small spring, a little distance from the 

 main sjorings, that yields water enough for 2,000 pounds of salt per day 

 for a portion of the year. It sells at $30 per ton at the works, and the 

 demand is increasing every year. The company began to supply the 

 market in 1866 at five cents per i)ound. It now sells at two cents per 

 pound. The amount annually made by the company for six years past 

 is as follows : 



Founds. 



1866 100,000 



1867 300,000 



1868 500,000 



Pounds. 



1869 650,000 



1870 750,000
