cost. We append a copy of the analysis, and accompanying letter from Prof. C. F. Chandler:

Laboratory School of Mines,
Columbia College, New York.
March 9, 1875.

Sir: The sample of Medina Sandstone submitted to me for examination contains:
Silica - 98.35 per cent.
Sesquioxide of Iron* - 42 per cent.

* Equivalent to 0.29 per cent, of Metallic Iron. "Bottle glass, which is dark green, or black, contains from 3.8 to 6.2 per cent, of oxide of iron. Plate glass contains from 0.2 to 1.9 per cent, of oxide of iron. Ordinary white glass contains from 0.3 to 3.9 per cent, of oxide of iron. Flint glass contains from 0.4 to 0.8 per cent, of oxide of iron. Assuming that the glass to be made of your sandstone will contain 75 per cent of the sandstone, the glass would contain less than one-third of one per cent, of oxide of iron, which is too little to give it any objectionable color, or practically to color it at all. I am satisfied, therefore, that the sandstone is in every respect, well fitted for the manufacture of glass of the best quality."
•       Signed,       C. F. CHANDLER, Ph. D.
Prof. Analytical and Applied Chemistry.

A large deposit of sandstone is found East of the city, on the line of the Chesapeake and Ohio Canal. The stone is a soft white sandstone, lying sufficiently near to the surface to be easily mined, and, from its proximity to the Canal, can be transported to the city easily and cheaply. We have no analysis of the stone; but practical tests have found it to be suitable for use in the manufacture of glass. It will cost, delivered here on the wharf, crushed, washed and dried, ready for use, about $4.00 per ton.

We call the attention of glass manufacturers to these deposits of excellent glass sand. To the inducement of prime sand, we add those of cheap fuel, firebrick of best quality at less cost than the same quality can be had in Pittsburgh or elsewhere ; a large local trade and excellent shipping facilities. We may add that owing to our nearness to the seaboard, imported chemicals, and crucible stock can be transported at low cost.

Timber.

IN addition to the mineral wealth stored beneath their surface, the hills and mountains of this region bear a large and valuable supply of timber. Every railroad westward from Cumberland has opened to this market a valuable
