exist in at least one locality, and this fact alone would be an 
inducement to seek for other treasures. 
Epidote, jade, turquoise, aragonite and zircons of the hya- 
cinth variety, have also been found, though the country as yet 
has not been scratched over. 
Among the really unusual deposits found in this section is a 
ledge of palagonite near the San Isabel valley. Though not a 
true mineral, being an alteration of tufa, resulting through 
the agency of steam or hot water, its presence is notable, as rare 
in this region. It is named from the place it was first found 
in Italy. j 
This deposit consists of a series of different colored ledyes, 
each of which is well defined. They are continuous, the only 
line of separation being a marked change in their color. These 
ledges vary in width from five to twenty feet, forming a solid 
mass of material eighty feet wide. The natural colors of the 
higher grade varieties are umber, Indian red and sienna. This 
material when extracted is soft and can be cut with a knife, | 
but when exposed to air it hardens and will take an excellent 
polish. Besides being available as a decorative stone, it can 
be used in the manufacturing of paints, paint filler, soap filler, 
sapolio, tooth powder, kalsomine, putty and polishing powder. 
Still another unusual and interesting deposit is found in the 
mountain range chiefly near the desert’s edge. It is a deposit 
of gabbro, granitoid, consisting chiefly of labradorite and 
pyroxene, containing hornblende and magnetite. Specimens 
of this orbicular gabbro have been polished and are truly beau- 
tiful. Were it possible to mine this in large quantities there 
would be a demand for it for decorative and ornamental 
work. 3 
In view of the fact that only the most meager investigations 
have been made of the mineral resources of this section, it is 
truly remarkable that so many rare and valuable minerals have 
been found. There are most promising indications to indute 
the mineralogist to seek for the hidden things and within a 
short time others may be brought to light. 
HEAR! 
Dr. Jacques Loeb, of the University of California, protests, in 
Science, against the sensational newspaper reports of his work, 
disclaiming their ‘‘idiosyneracies,’’ in the interest of the dig- 
nity of scientific research. AMEN!!!
