sides have fallen in. Fig. 19 shows 22 feet of lump and wash ore, with 

 ore in the floor. 



The excavation shows that some 25,000 cubic yards, or 35,000 tons of 

 ore have been removed. About 1^ miles west 20° south from the Knaub 

 Bank the Wolf Bank is now being opened on the same terrace on the 

 mountain side, immediately on the bank of the same excellent washing 

 stream. Assuming the depth of ore showing at the Knaub Bank as 

 persistent, we have between these two banks 6000 cubic yards or 9000 

 tons of ore for every yard mined north and south along the dip of the 

 bed. 

 No. 21. McCormick Bank.—' Lies about 2 miles west 35° south from 

 PIG. 19 Dillsburg, and half a mile from York 



Springs Branch Railroad. The bank 

 has not been worked for some years, 

 and the sides have slipped down. 

 The present face shows 10 feet of 

 wash and lump ore, and a shaft from 

 which ore was mined went down It) 

 feet in ore, making 26 feet. The ore 

 was used in Harrisburg, and Mr. 

 McCormick reports the quality very 

 good. The amount of ore removed 

 must have been quite large, as the 

 bank was opened 60 years ago, and 

 worked, with intervals of rest, up 

 to 4 years ago. As the worked-out 

 portions are filled with stripping and 

 wash no estimate can be made of 

 quantities. The dip of the ore is very 

 decided, south 45° east, 25°. Min- 

 ing has been done hitherto by run- 

 ning along the line of strike and go- 

 ing down the dip until the water 

 .stopped work. The expense of hauling the ore 11 miles to Mechanicsburg 

 on the Cumberland Valley Railroad, proved heavy, and the mine was for 

 the time abandoned. Within a half mile south 15° west from McCor- 

 mick *s bank, there are two old banks from which considerable ore has 

 been hauled in the past, but which are now fallen shut. 



II. Magnetic Iron Ores.— The branch road strikes these ores about 1 

 mile east of Dillsburg. There appear to be five beds, the thickness of 

 which is reported as follows : 



No. 1. Small. Most northerly bed, 

 " 2, 3 feet. 

 " 3. 5 to 12 feet. 

 " 4. 4 to 7 feet. 

 " 10 + feet.
