MINE WORKINGS OF FRYER HILL. 455 



correct. The intersections of the drifts with these sections show to what 

 degree the plane of the section has been actually explored, but the outlines 

 of the formations as indicated there are determined also from analogy and 

 by deduction from observations made in the vicinity, but not actually on 

 the section plane. 



On the surface map the outlines of the various claims are indicated by 

 broken lines. These are sometimes difficult to trace, owing to their coinci- 

 dence with lines of drifts or with the blue lines representing the lines of 

 the different sections. They are given as accurately as could be deter- 

 mined by the engineers who had been employed in surveying them ; but, 

 as invariably occurs in rich mining districts, there are many cases of con- 

 tested boundaries between adjoining claims which have either been settled 

 by compromise or are still in litigation, so that the lines here given cannot 

 be assumed as officially and finally correct. The laying down upon an 

 accurate topographical map of a mining district like this of finally correct 

 side lines to the many claims that are there located, if not an absolute 

 impossibility, would require an amount of time entirely incommensurate 

 with the value of the result to be obtained, as can be readily understood 

 by those familiar with the working of the land system of the United States 

 as applied to mineral claims. In describing the various mine workings 

 and ore bodies of this group, they will be taken up in geographical order, 

 proceeding from west to east, without regard to priority of discovery.

chrysolite mine. The property of the Chrysolite Mining Company con- 

 sists of the following claims: Carboniferous, Chrysolite, Vulture, Little Eva, 

 Colorado Chief, Pandora, Fair View, Kit Carson, and All Right. The 

 greater part of the ore extracted from this property has been obtained from 

 the first three claims. The area occupied by the others, as shown by the 

 map, is mostly west and south of the outcrops of the main ore body, indi- 

 cated in dark blue crossed in black; in other words, over this area the ore has 

 been mainly removed by erosion. The Discovery shaft of the Chrysolite 

 has, so far as known, discovered no ore. The first considerable ore body 

 was opened by Vulture No. 1 shaft, near the northern end of this claim.
