BUILDING STONE. 625 
A quarry 4 miles north of Lima is said to produce some material of 
much better quality. It is situated near the Dayton and Michigan 
railroad, but a side track could not be constructed to it without con- 
siderable expense on account of the heavy grading that would be 
necessary. Some of the courses are over | foot thick, and some from 
4 to 6 inches thick have been used for sidewalk paving in front of the 
Lima Machine Works, where it gives indication of both strength and 
durability. The following is a section of the strata in the quarry :

There is no natural drainage below the paving stone, and for this 
reason the underlying blue-stone has not been extensively quarried. 
According to the testimony of all builders and contractors the stone in 
the bottom of this quarry is the best building material found within a 
radius of at least 30 miles. The shaly rock which overlies the blue- 
stone forms good material for the macadamizing of roads. The material 
above the paving stone, which is used for foundations, occurs in thin 
beds which are never more than 3 inches in thickness. 
The specimen which was sent from this quarry was taken from the 
lower or “‘blue-stone” layers ; it has a dark-gray color, finely banded 
with yet darker lines, and much more compact than most of the stones 
sent from the quarries in the Helderberg. Indeed, no pores or cavities 
were found in it, and its texture was such that it admitted of a fair 
polish, as indeed do most of the Helderberg limestones. ‘The stone 
from this quarry is a. dolomite, but on being dissolved in hot acid quite 
a large residue of argillaceous character is left undissolved, and it con- 
tains bituminous substances which impart to it the character of a fetid 
limestone. It contains little or no iron. 
A quarry is situated 53 miles zortheast of Lima, and the following 
section indicates its character and the uses to which the stone is applied :
