MINES - FAIRPLAY DISTRICT. 701 



son commenced mining here again in July, 1876, with a steam pump, and has sunk four 

 shafts. The workings are about 120 feet deep in the second opening, and in the third, 

 which is about 25 feet below the second. The mine has not produced much yet, as the 

 time has been mostly consumed in preliminary operations. 



Peak & Blair. N. W. qr. Sec. 26. These parties have also been working on the 

 Craig range during the past summer (1876). They have a flat sheet of lead ore about 

 five inches thick in the first opening, which here averages 20 feet in width. This range 

 has been worked during the last forty years. The product of the present parties has 

 been about 20,000 pounds. 



Dutch Hollow Diggings. 



They are situated on the north half of Sec. 36, T. 3, R. 3 W., about two and a half 

 miles east of Potosi. The following parties are now operating here: 



Dutch Hollow Level Company. Mining operations have been earned on here con- 

 tinuously for the last six years, excavating a level on or near the upper surface of the 

 Blue limestone. The level is now about half a mile long, and it is expected to reach the 

 main shaft in about a month. When completed, the level will unwater all the Galena 

 limestone above it, which is here about one hundred feet thick. It is expected to un- 

 water the Kendall, and many other old ranges in the vicinity, as deep as the third open- 

 ing. The level is not producing much now. During the year 1872, it produced 60,000 

 pounds. 



Rnp & Son. X. E. qr. Sec. 35. This party has been working during the last six 

 months on a part of the Ziig range. The ore is found in the first opening, which is 

 here about 15 feet wide. The production has been 150,000 pounds. 



Zug Diggings. This is an east and west range, being the same range and opening 

 as the preceding. It is worked to a depth of 75 feet. The present party has mined 

 here during the last year and a half, and produced 150,000 pounds. 



LangstafP & Gillan. Situated three-quarters of a mile northeast of the preceding, 

 on the creek in Sec. 25. The lead ore is found here in a flat sheet in the first opening, 

 near the water level and about 30 feet below the surface. Three men have been work- 

 ing here twelve months, and have produced 60,000 pounds. 



The production of the Potosi district, including Rockville, British Hollow and Dutch 

 - Hollow, could not be definitely ascertained, as very little record has been kept of it. It 

 is estimated at 80,000 pounds per annum. 



Mining in this district is generally abandoned in summer for farming, and resumed 

 again in the winter, in the lack of other employment. In this way a large number of 

 men are at work in the winter, each raising a small amount by prospecting, which forms 

 in the aggregate the total product of the district. 



FAIRPLAY DISTRICT. 



The only mines in this vicinity which have recently produced anything are those of 

 Black & Co., on the N. E. qr. of Sec. 24, T. 1, R. 2 W., and those of Williams & Co., 

 near the center of Sec. 19, T. 1, R. 1 W. 



Black & Co. This property, which comprises in all about two hundred and 

 forty acres, is owned by Messrs. Joseph and Thomas Sparks. It has been known to be 

 rich ground for many years, and to contain, besides the ore, an immense amount of water, 

 which was the chief obstacle t& be overcome. Previous to the operations of Mr. Black, 

 it had been attempted by three separate parties, at as many different times, but always 

 with more or less loss. 



Mr. Black commenced work on it in November, 1871, by means of pumping, and
