RECENT ARRIVALS. 
ZEOLITES. From the recently discovered locality on the Columbia 
River, Oregon. Our collector was successful in obtaining for us what is 
considered to be the finest Sphaerostilbite yet found. It occurs with the 
Chabazite in lustrous, translucent balls which are grouped or scattered singly 
over the matrix in a very charming manner. . 
Minute crystals of Chabazite coating compact balls of Thomsonite is another 
unique occurence. 
Chabazite Coating Stilbite Crystals. ; 
Microscopic Chabazite, mounted on the sides and ends of the needle-like 
Natrolite.. A tuft of this Natrolite sprinkled over with these brilliant and 
dainty rhombohedrons makes a most beautiful microscopic mount. 
Chabazite, in splendid groups of white and colorless crystals. Isolated 
crystals, with sharp angles and perfect symmetry outlined on a background 
of yellow gangue. The gem-like perfection of some of these specimens 
resembles that of the Cyclopean Islands Analcites. 
Stilbite in beautiful groups of crystals. 
Harmotome, Heulandite, Apophyllite, Etc. 
Prices on all the above species are as low or lower than those on Zeolites 
from any of the older localities and there are among them certain types 
which are entirely new. 
Very beautiful specimens for drawer or case, 50c. to $2.50. Choice small 
specimens, 5c. to 35c. 
RUTILATED QUARTZ FROM NEW ZEALAND. A number of 
specimens, pronounced to be the finest quality in the world, have been 
received. Masses of clear Rock Crystal three to five inches in diameter, 
showing in their depths the slender golden red crystals of Rutile. They 
make by far the handsomest polished specimens of this gem mineral that 
have yet been seen. 
The locality is new and very little of the material has been placed on the 
market. Prices 3.00 to 15.00 for choicest specimens. 
Semi-opal from a new locality in Washington. Translucent, olive green 
masses, mottled with red. Also brick-red and other shades. Specimens are 
of great beauty when polished, as their hardness and clear quality give a 
high natural lustre even on broken surfaces. 5c. to $1.00.
