A detailed statement of costs could not be obtained; but the mine is said to 

 have yielded a net profit of $40,000 during the summer. 



The mine is provided vs^ith a small hoisting engine. Both rock and 

 water are raised in buckets. Four hours per day are required for the engine 

 to raise the water from the mine. From reliable sources the yield of this 

 mine to its owners, from January 1 to August 1, 1870, appears to have been 

 about $75,000, including the product of the first-class ore. This latter 

 amounted to 409 tons, of which the average price paid in currency by the 

 smelters to the mine was $41 90 per ton. 



GuNNELL Lode. — North of Quartz Hill, separated from it by Nevada 

 Gulch, and lying between the latter and Eureka Gulch, is Gunnell Hill, which, 

 since mining first begun in Colorado, has been the scene of active work. Its 

 general trend is east and west, and it contains a number of valuable veins, the 

 general course of which is east and west, or between that and northeast and 

 southwest. The most developed of these is the Gunnell lode, that crops out 

 on the northern slope, not far below the crest of the hill, and which has been 

 worked to a depth of about 500 feet, the opened mines covering a length of 

 nearly 1,200 feet. The general features of this lode are said, to be much the 

 same as those of veins already described in this chapter ; but, as none of the 

 mines were working during the writer's visit to the region, there was no fa- 

 vorable opportunity afforded to go underground. The vein is said to have 

 been one of the most productive of the country in early days, and it possesses, 

 doubtless, as much merit as many of those that are now being wrought; but, 

 owing to various difficulties and hinderances, some of them quite independent 

 of the intrinsic merits of the property, the work of mining on this lode was 

 suspended some time ago, and is not yet resumed. The principal mines on 

 this lode are supplied with hoisting and milling machinery, and the increas- 

 ing activity attending mining operations in Colorado will be likely to occasion 

 renewed efforts to bring them into successful and profitable operation. On 

 this hill are several other less developed, but very promising, ledges, some of 

 which have been lately opened. Among these is the Fairview, which was 

 first brought into notice in the early summer of 1868. It has since been 

 worked steadily, producing rock of excellent quality, and, it is said, has been
