MINES HIGHLAND DISTRICT. 725 



These diggings consist partly of old, and partly of new workings. Cross cut drifts 

 are run through the old works in search of new ground, lead ore being usually found in 

 the lowest opening. These parties have been working since 1870, and their product is 



as follows : 



Lead ore, Smiihsonile, 



Tear. Ibs. torts. 



1870 70,000 70 



1871 70, 000 70 



1872 80,000 80 



1873 : 90,000 90 



1874 90,000 90 



The production of the years 1875 and 1876 was net ascertained. 



Harris & Stanley. Situated on the ground of Dr. Stanley, about 300 feet north of 

 the windmill on Kennedy & Co.'s ground, previously described. These diggings are 

 quite dry, being drained by the windmill pump. The range appears to be a branch of^ 

 the Drybone Hollow range, about 500 feet long, running in a north and south direction. 

 There are two principal openings exhibited in the following section of their working 



shaft:

The ore occurs as usual in this district, in flat sheets. These parties have been work- 

 ing here since September. 1871, since which time to October, 1874, the total product was 

 as follows: lead ore, 40,000 pounds; blende, 35 tons; Smithsonite, 75 tons. 



Rowe & Co. Situated on the N. E. qr. of Sec. 28, T. 7, R. 1 E, comprising 160 

 acres. This is an east and west range, known as the Dunstan, discovered in 1846, and 

 worked continuously since. It is about half a mile long, and 200 feet wide. The range 

 is worked in the Brown-rock opening, chiefly for Smithsonite and lead ore. There are 

 three working shafts from 50 to 75 feet deep. The opening is from 5 to 20 feet high. 

 Their annual product is stated at, lead ore, 50,000 Ibs., and Smithsonite, 50 tons. 



This was all that could be elicited relative to this ground, as the owners were quite 

 reticent on the subject. 



The foregoing comprise all the diggings in the imnu diate vicinity of Highland, and, 

 with the exception of the last (Rowe & Co.) they are all embraced in a tract of land 

 not exceeding forty acres in extent. The same general geological characteristics pic- 

 vail in all, and they are nearly all connected together in the workings. The ore in most 

 of them has to be crushed and jigged, and all except Kennedy and Maguire have to 

 haul their wash dirt about a mile and a quarter to water. 



In these diggings, the openings below the top of the Blue limestone have never been 

 worked or even prospected. If the several land-owners would take some concerted ac- 

 tion, a level might be run up the Drybone Hollow, which would drain them to any depth 

 required. Such a work, however, should be preceded by boring, to ascertain the pres- 

 ence of flat sheets in the lower openings, the existence of which is not improbable. 



Mr. Solomon Spensley, who is well informed on the subject, says that the annual av- 

 erage product of the mines is approximately as follows: Lead ore, 1,000,000 Ibs.; dry- 

 bone, 1,350 tons; blende, 1,200 tons. In addition to the preceding, there are some dig- 

 gings situated south of the village of Highland. 



Davis & Co. Situated near the S. E. cor. of Sec. 5, T. 6, R. 1 E. This is a north- 

 west and southeast range, discovered by a Mr. Styles in 1862. It has been proved to a
