102 GEOLOGICAL SURVEY OF THE TERRITORIES. 



visit of one who loves the beautiful. We did not have time to penetrate 

 farther up the canon, but below these sandstones I believe there are 

 Carboniferous limestones. The thickness of these rocks, however, is not 

 very great. I cannot give the exact thickness, as I had no means of 

 measuring them. 



Leaving Glen Eyrie we passed a second time through the " Garden of 

 the Gods", and after a ride of some six miles reached the Springs on the 

 Fontaine qui Bouille, a branch of the Arkansas River. There are five 

 l^rincipal springs. The first one is the " Manitou" or " Doctor Spring." It 

 is on the left bank of the river, and is quite small, measuring hardly a 

 foot in diameter. The water contains a large percentage of carbonic 

 acid, and there is a slight bubbling, caused l3y the esceipe of the gas. 

 The water is more agreeable to the taste than that of any of the other 

 springs. There is quite an abundant deposit of carbonates about the 

 spring reaching to the edge of the river. The overflow of water is very 

 small. The water contains about two drachms of solid matter to the 

 gallon. Its temperature was 57° F. It is feebly alkaline. An analysis, 

 made by Mr. Frazer in 1869, revealed the following contents : 



Carbonate of soda. 



Carbonate of potassa. 



Carbonate of lime. 



Chloride of sodium. ^ 



Alumina. 



Trace of iron. 

 The next spring is the ^' Comanche." This is a chalybeate spring, 

 situated in a small thicket, ou low, marshy ground, on the right bank of 

 the river, near the water's edge. There is no deposit about, save a 

 slight one of oxide of iron, and the escape of gas is very insignificant. 

 The iron is quite perceptible on tasting the water. Its temperature was 

 4S0.5 F. 



The next spring, in size the second, is the " Shoshone." It is also on 

 the right bank of the river, and is close to the wagon-road. - There is a 

 continuous escape of carbonic-acid gas from it, but the taste of the 

 water does not compare with that of the Manitou. It is surrounded by 

 considerable deposit, consisting mostly of carbonates of soda and 

 potassa, with also a trace of sulphur. (Frazer, 1869.) Its temperature 

 is 55°.5 F. Below the Shoshone Spring, on the edge of the river, is the 

 " Nashataga," an unimportant spring, having a temperature of 52° F. 



The largest spring is the "Bathing Spring." It is almost opposite 

 the Manitou, and has a very abundant deposit, in which the opening 

 of the spring is about five feet in diameter. The escape of gas is more 

 violent than in any of the other springs. Its temperature is 60° F. 

 Water is couveyed from it in iron pipes to a bath-house, which has been 

 recently erected. An analysis of the deposit from these springs, made 

 by Dr. Drown in 1871, is as follows : 



Per cent. 



Chloride of sodium ,, 36. 69 



Chloride of potassium 10. 01 



Bicarbonate of soda 24. 01 



Sulphate of soda 4. 78 



Bicarbonate of lime 15. 62 



Bicarbonate of magnesia 8. 89 



Total 100.00 



The names of some of the other unimi^ortant springs are the " Iron 

 Ute," "Navajo," the "Arapahoe," and the "Pawnee."
