replaced by sand-rock. The Hone ore is a local deposit, or pocket, on the 
summit of a knob, and covers from one and a half to two acres. It is 
seven feet thick in the center of the deposit—in one place swelling to 
eight feet, but becoming thinner at the outcrop. It is covered with clay 
from one to ten feet thick, but the covering has admitted the air, and the 
whole body of the ore is thoroughly oxydized. There is little appearance 
of lamination, and no traces of carbonaceous matter were detected. The 
ore was doubtless originally a carbonate deposited in the form of a mud 
remarkably free from silica and alusiina. The borings, where the ore 
is seven feet thick, were intimately mixed, and constituted a sample, 
which, analyzed by Mr. H. 8. Gregory, of Youngstown, showed the fol- 
lowing constituent elements:

The ore is rich in iron, and is easily smelted. It is easily dug, and is 
delivered by railroad to the furnace very caeap_y. There are probably 
15,000 tans in this single deposit. 
Another deposit of ore which is believed to be in the horizon of the 
Tron Point ore is found on the Whitlock farm, a little north-east of Mox- 
ahala. This deposit is irregular in outline, and the extent is not well 
ascertained. The ore where first opened is laminated with occasional ° 
films of coal formed from isolated fragments of coal plants. On the out- 
crop the ore isoxydized and dark red in color; but under cover it becomes 
a regular black-band, according to Mr. Chamberlain. I have no full anal- 
ysis of this ore, but it appears to be of excellent quality, and has proved 
itself such in the Moxahala Furnace. A single determination of the 
iron in the oxydized portion of the ore, showed 44.50 per cent. of metallic 
iron. 
More recent developments of the Whitlock ore show a change from a 
black-band to the unstratified oxydized character of the Hone ore pre- 
viously described. The ore thus changed is very fine, yielding over fifty
