The distance from Xo. 1 to Xo. 5 is from 800 to 900 yards. The beds 

 dip north 20°. East and west along the strike of the beds for 300 to 400 

 yards, shallow pits have been opened on the beds, and ore taken out until 

 the water stopped the work. These scattered openings extend over a 

 considerable area, and, in the aggregate, much ore has been removed. 

 At present (May) only one small pit is being worked — Mr. Underwood's. 

 On Bed Xo. 3, Mr. McCormiek of Harrisburg has mined a large amount 

 of ore. He was provided with the necessary engine power and went 

 down 80 feet, mining on slope along the dip of the ore. Gangways were 

 then driven east and west in the ore. The expense of hauling 10 or 11 

 miles to Mechanicsburg rendered the works unprofitable, and the mine 

 was abandoned and is now filled with water. 



Two miles north of Petersburg in Adams County, on Lerew's place. 

 there is an outcrop of magnetic ore. Xo opening has yet been made, but 

 the place is leased and work is to bagin at once. 



Traces of magnetic iron ore have been found about half a mile south 

 of Boiling Spring Furnace at the north foot of the South Mountain in 

 connection with the trap dyke. 



An outcrop of magnetic ore is found south of the Yellow Breeches 

 Creek, running from tbe mouth of Dogwood Run east as far as Lower 

 Milltown, on the Xelson, Xisely, Urich, Bishop, and Stayman farms. 

 At Stayman's a pit has been sunk and the indications are reported as 

 favorable. 



One and a-half miles up Dogwood Run, specular iron ore crops at the 

 surface. Xo opening has been made. An outcrop of specular iron ore 

 is also found in the South Mountains, 4 miles south of Boiling Springs 

 Furnace. 



III. Sand.-r-Kt the mouth of Dogwood Run, an extensive flat is covered 

 to a depth of 10 feet with a very pure sand. About 1000 tons have been 

 shipped to Harrisburg for moulder's use. It is sufficiently valuable to 

 bear a charge of $2 for hauling and freight, and with cheap transporta- 

 tion by railroad, would probably be shipped in increased quantities. 



An excellent sand, suitable for furnace use, is opened at Boiling Springs 

 Furnace. It lies between limestones somewhat altered, and comes from 

 a friable altered sandstone. It is found on the "Trap-dyke Ridge. 1 ' 

 Good sands are opened at Papertown. 



IV. Limestone. — The valley limestones, making usually the north bank 

 of the Yellow Breeches Creek, are found along the whole line of the road ; 

 and are of all qualities ranging from burning to the hardest building 

 stones. At Milltown, 8 miles east of Boiling Springs, 9 miles west of 

 Harrisburg, the limestone is peculiarly excellent for burning, and about 

 100,000 bushels a year are now made there. The amount can, of course, 

 be indefinitely increased with the enlarged market afforded by cheaper 

 transportation.
