ON "CALIFORNITE." 
By F. W. Clarke and George Steiger. 
In 1901 Mr. G. F. Kunz a called attention to a remarkable massive 
variety of vesuvianite, discovered in California by Mr. A. E. Heigh- 
way, and which at first was thought to be jade. A second locality foi 
the mineral, remote from the first, was found some time later, and 
here the vesuvianite was accompanied by another substance, which 
proved upon examination to be an unusual modification of garnet. 
For the vesuvianite Mr. Kunz proposed the varietal name "califor- 
nite," and at first the garnet was supposed to be the same species, bul 
different in color. Samples of all three minerals were sent to the 
laboratory of the United States Geological Survey for analysis, anc 
the results obtained are given below. 6 
A. Vesuvianite from the south fork of Indian Creek, 12 miles fron 
Happy Camp, Siskiyou County, Cal. 
B. Vesuvianite from Fresno County, Cal., 35 miles east of Selma. 
C. White garnet, found with or near vesuvianite B.
