192 II. B. PATTON TOPAZ-BEARING RHYOLITE, UTAH 



Thomas range is very far from the truth. The crystals are abundant in j- 

 onl}^ a comparatively limited area — say an area half a mile or less in each 

 direction. Undoubtedly the crystals are present over this area in mil- 

 lions, but they are mostly very small, the larger ones having long since 

 been picked up. They abound in the sand of the dry stream beds, and 

 may be thus traced for miles. These minute crystals shine, too. Just as 

 brilliantly in the sunshine as do the larger ones, and if one endeavors to 

 locate a good sized crystal by the brilliancy of its sparkle, he will find 

 himself engaged in the miprofilable, not to say undignified, occupation of 

 chasing up pinheads.
