Quicklime sells generally at eighteen cents per bushel at the kiln, but 

 sometimes at twenty cents. The lime of the Delhi beds is of a brownish- 

 white color, with darker spots and specks. The annual average product 

 of the quarries of Philip Jones, Wm. P. Jones, and Samuel Perry, near 

 Delhi, Aggregates 11,420 bushels. The kilns of Mr. Corbin, at Delaware, 

 consume much more wood per one hundred bushels than any other in 

 the county — indeed, more than any in north-western Ohio. They are of 

 very large capacity, and usually are not entirely filled. The kilns of Mr. 

 Colvin are also pronounced ill-shaped by Mr. Schmidt, who has run them 

 for several years. There are no kilns in the county made on the latest 

 improved plan. No progress whatever is exhibited in the methods em- 

 ployed. They are the same as the methods adopted by the earliest man- 

 ufacturers, and should give place to the improved methods of some of the 

 late patents. 



The uses of the Huron Shale.— The only known use that can be made of 

 the Huron shale, with strong probabilities of success and profit, is in the 

 manufacture of hydraulic or water cement. The manufacture of petro- 

 leum, illuminating gas, and of roofing-slate, has, in each case, proved 

 profitless. Some have employed it as a material for roads, but it is found
