almost continually throughout the summer months ; even the 
Ysleta Indians come there to bathe for their ailments. These 
sources of health and cleanliness are on Indian lands, whence 
the name. Should they be properly cared for there is reason 
to believe that they would afford a health resort of the first 
class. 
The Jcnicz Hot Springs. — The Jemez hot springs or "Ojos 
Calientes," as the Mexicans call them, are situated in the Jemez 
river bed in Caiion San Diego at Perea. The site is a beauti- 
fully picturesque one. The Red Bed walls of the canon rise 
1200 feet on either side of the river, while in the valley a little 
north of the springs is the ruins of the Indian village of San 
Juan de los Jemez and the Spanish Catholic church and forti- 
fication of the first occupation of the Spaniards. 
These springs are located geographically in two groups. 
The lower group is owned by a man by the name of Judt, and 
the upper one by the Oteros. Each firm has erected comfort- 
able bathing houses and sweating rooms. Hotels have also 
been erected for the benefit of the health seekers. A stage also 
runs between these springs and Albuquerque. 
The temperature in Judt's group of springs is 119° F. The 
specific gravity is 1.0016, and the chemical analysis shows the 
following :
