long been famous for their medicinal qualities. As early as 1868 the 

 writer spent a summer at these springs. At that time there were no hotel 

 accommodations, and the visitors brought along their camp equipments and 

 pitched their tents under the shade of the trees. The bath house was a tem- 

 porary structure, made of canvas over the principal upper spring. An oc- 

 casional raid in the vicinity by the Comanche Indians kept the visitors most 

 of the time in the camp. Now everything is changed. The railroad brings 

 hundreds of visitors every year. Large and commodious hotels with mod- 

 ern improvements and conveniences are there; the grounds have been en- 

 closed and the natural growth of trees trimmed; a large and convenient 

 bath house has been constructed, where one can have either a hot or cold 

 bath, as his inclination or necessities may require; a street car runs from 

 one spring to the other, the two being situated about one mile apart, and 

 everything is done to make the stay of the visitors pleasant. Invalids and 

 visitors can secure such accommodation as their ability to pay for will war- 

 rant. 



There are two principal springs. The Hanna Spring is the one farthest 

 east, and is on the east of and nearest to the town. It has a flow of 2500 

 gallons of water per minute, and a temperature of 71 degrees Fahrenheit. 

 These waters are variable in the amount of mineral salts they contain, and 

 they alternate in these changes. When the Hanna Spring is highly impreg- 

 nated with salt, the Hancock Spring is weak; and when the Hancock Spring 

 is highly impregnated the Hanna Spring is weak. They are evidently both 

 from the same source, and owe these periodical changes to the flowing into 

 them of water from other sources than that which furnishes the salts, in 

 variable quantities at different times. 



The following analysis was made of the water from the Hanna Springs by 

 E. Waller, Ph. D., of New York, per United States gallon of 231 cubic 

 inches:
