Hulburton, Orleans County. — This group of quarries is west 

 of the village, on the north side of the canal, stretching along a 

 distance of two and a half miles. * They are all worked to a 

 depth below the canal water-level, and pumping is necessary to 

 drain them. The stripping of drift-earth does not exceed ten 

 feet. Some of the beds are thick, and blocks of. large size are 

 obtained. The stone is mostly fine-grained, and light to dark- 

 red in color. The best quality is shipped for building stone. 

 The greater part of the product is split into paving blocks and 

 crosswalks and curbstone, which are shipped to Eochester, 

 Buffalo and western cities. 



Much of the Hulburton stone is sold under the name of Medina 

 block. Examples in construction are the Delaware Avenue 

 Methodist Episcopal Church, Buffalo, and Sibley College, Cornell 

 University, Ithaca. 



Albion, Orleans County. — The largest quarries of Medina 

 sandstone are at Albion. They are east of the town, between 

 the canal and the New York Central railroad. The parties here 

 at work are : Goodrich and Clark Stone Company, Albion Stone 

 Company, and Gilbert Brady, of Eochester. The stripping on 

 the sandstone is from three to fifteen feet thick. The beds dip a 

 few degrees to the south, and are of varying thickness, from a 

 few inches up to six feet. Eegular systems of joints facilitate 

 greatly quarrying operations. There is considerable variation in 

 the nature of the stone in the several beds, and even in the same 

 bed, as followed in the same quarry. Generally it is of a light- 

 red color, and fine-grained. 



A specimen representing the best building stone, as quarried 

 by Mr. Brady, has a specific gravity of 2.598, and a weight (cal- 

 culated) per cubic foot of 162 pounds. The percentage of oxide 

 of iron is comparatively low, being 0.51 and C.09 for ferrous 

 oxide and ferric oxide, respectively. The absorption test gave 

 2.37 per cent. The losses in weight, in the tests with carbonic 

 acid gas and sulphurous acid gas, were 0.09 and 0.29 per cent. 

 The treatment with sulphuric acid, 1 per cent, solution, occa- 

 sioned a loss of 0.08. The alternate freezing and thawing pro-
