MINES MIFFLIN DISTRICT. 721 



Dutch Range. The range was discovered in 1840, and has been worked nearly 

 every year since. It is a quarter of a mile long. The ore is found in bunches mixed 

 with blue clay, in the first opening, which is from fifteen to thirty-five feet below the 

 surface. No ore is found in the lower openings. It has produced in all 200,000 pounds, 

 and its present annual average is 5,000 pounds. 



AVilkinson and Cronin Range is a quarter of a mile long, and was discovered in 

 1868. The ore is found partly in the first, and partly in the second openings, which arc 

 here eight feet apart. It is from five to thirty feet from the surface to the top of the 

 first opening. There are here two ranges which have produced 300,000 pounds, and 

 the range is now nearly worked out. 



Smith Range. This differs from any of the Whig ranges before mentioned, in hav- 

 ing its course north and south, instead of east and west. The range is about an eighth 

 of a mile long, and the distance from the surface to the top of the opening is from ten 

 to sixty feet. The sheet was from one to four inches thick, and was worked in one 

 place down to the Blue limestone. The principal bodies of ore were found in the Brown 

 rock opening, which is much lower than the general run of openings at these diggings. 

 The range is said to have produced 200,000 pounds, and is now worked out. 



Big Patch Diggings. 



The greater part of this group of diggings is situated in section 10, T. 2, R. 1 W. 

 The general course of the range is N. 65 West. The ore is found here in crevice open- 

 ings, and usually in the first opening. The following parties are now mining here : 



Dixon & Coats produced since February, 1876 400,000 fi>s. 



Casper Linden produced since March, 1876 25,000 " 



Tapper & Trowbridge produced during August, September, and 



October, 1876 12,000 " 



Peacock & Co., annual product 18,000 " 



Todd & Co., annual product 10,000 " 



Haverncss & Co., annual product 15,000 " 



Spink & Co., annual product 20,000 " 



Hawkins, Thomas & Co. S. W. qr. of Sec. 31, T. 3, R. 1 W. This is a discovery 

 of the year 1872. The ore is blende, somewhat mixed with rock, and occurs in a flat 

 sheet on the upper surface of the Blue limestone. The sheet has in some places a tlu'ck- 

 ness of five feet; it lies in the bed of a small stream, and a level to drain it is partially 

 completed. About 27 tons of ore have been produced. 



MIFFLIN DISTRICT. 



Mining operations heie are now chiefly confined to several parallel ranges, having a 

 general northwesterly course, and situated about half a mile south of the village, in- 

 cluding the Penitentiary, Dunbar and Owens ranges. The ore is found in flat sheets on 

 the surface of the Blue limestone, in the pipe-clay opening. Some mining is also done 

 on Sec. 10, T. 4, R. IE., in the vicinity of the Welsh settlement. 



Penitentiary Mine. S. W. qr. of N. E. qr. Sec. 34, T. 5, R. 1 E. This property is 

 owned by Messrs. James, John and Calvert Spensley, Wm. Bainbridge, J. J. Ross, 

 Mrs. Mitchell and N. W. Dean. The mine was opened in 1842, and since then it has 

 been very productive, and has been worked continuously to the present time. The mine 

 is drained by a level containing a tramway on which the rock and ore are carried out of 

 the mine. Sufficient water is removed to operate a large wash place. The distance 

 from the entrance of the mine to the, forehead is about 1,700 feet. The average width 

 of the range is about 300 feet, and the thickness of the deposit from six inches to two
