GOLD MINmG m COLOEADO. 529 



wheel, K, vvhicli is driven by a pinion, k, and may be constantly in motion, 

 whether the spool be in revolution or not; by means of gearing L, I, a 

 line shaft, m, transmits power to the spool N, which is operated in manner 

 similar to that just described. The pinion o, and spur-wheel O, are provided 

 for driving the pump, which is not yet placed in the shaft. All the minor 

 appurtenances of the works, such as water-supply, force-pumps, wood-yard, 

 and sheds, and similar conveniences, are quite complete, and the establishment 

 is unsurpassed in Colorado as regards method of arrangement and fitness for 

 its purpose. 



The mill in the building adjoining the west shaft-house contains 22 stamps, 

 weighing 550 pounds each, and has a crushing capacity of about 20 tons per 

 day. The average yield of the stamp-rock has been already shown to be about 

 $15 50, coin, per ton. The mine was producing regularly in 1868, but all its 

 yield and more has been absorbed in the costs of the work already described, 

 which is said to have involved the expenditure of more than $ 1 00,000. In 

 1869 the company became much embarrassed financially, and its regular 

 operations were interfered with, although some work was still in progress. 



Gardner Lode. — The Grardner lode is nearly parallel to the Illinois and 

 between 300 and 400 feet further north, its outcrop being further down the 

 slope of Quartz Hill, toward Nevada Grulch. Its course is north 85° east, true. 

 Its dip is 75° to the south, and both course and dip, so far as observed by the 

 writer, are very regular. The lode was discovered and partly opened as early 

 as 1860, and has been worked, with some intervals of interruption, from that 

 time to the present. It has been claimed and somewhat developed for a 

 length of over 800 feet, but the most important operations on the vein are 

 in the Clark-Gardner mine, a claim of 200 feet in length. The adjoin- 

 ing claims, both east and west, have been worked to varying depths, not 

 exceeding 200 feet, and have yielded some handsome returns, and as they are 

 partly owned and controlled by the same people who own the Clark-Gardner, 

 there is some hope of a consolidation of interest that will bring at least 800 

 feet under one management. This is much to be desired for the interest of 

 all owners, as under the present conditions the costs of equipment, opening of 

 ground, and administration of such short claims are so great as to absorb a 



large share of the proceeds.
