Report of the State Geologist. 



for brick masonry or for plaster work in houses, but making a 

 good stone mortar. The road was two years in building (the 

 peculiar conditions of an asylum permitting it), and has stood 

 five years on a steep grade with very little wear, being slightly 

 guttered in places, owing to the steepness of the grade. Mr. 

 Kitson informs me, however, that it has not been mended in 

 these five years. A steam roller was not used in making it. 



In illustration of the hydraulic properties of the TuUy lime- 

 stone, analyses are here' appended. No. 1 was taken from the 

 northernmost exposure (quarry of Thompson Johnson) ; ]S"o. 2, 

 from locality of the quarry at Willard ; while I^o. 3 represents 

 the best ^' Seneca " limestone (Chamberlain quarry). They are 

 taken from the Transactions of the N. Y. State Agricultural 

 Society, 1850, p. 611 :

Gas Wells. 









A considerable number of wells has been bored in and around 

 Seneca Falls village, with the object of striking gas in the_ 

 Medina sandstone. The example was set at Waterloo several 

 years ago ; a single well was bored with moderate success. In 

 Geneva two were put down (1888, 1892), but neither was turned 

 to account, though the later one was doubtless worth the trouble 

 of saving. 



At Seneca Falls the enterprise was begun in 1887 by the 

 *' Phoenix Gas Co." This failed to meet obligations, and the 

 property was transferred. The present holders now furnish heat 

 and fuel to 150 families. The illuminating powers are inferior. 

 The daily product may be set down at 30,000 feet, sold at 25 

 cents a thousand. A cooking-stove heated without intermission 

 would, it was estimated, burn 500 feet of gas in 24 hours.
