to 1380 feet where the green noncalcareous shale was met, it is Hkely 

 that the top of the Chnton was missed and that the beds are only 

 partly represented in the aggregate of 125 feet above given. 



South Granby, Oswego co. A nearly complete section of the 

 Clinton formation was afforded by the test hole put down at South 

 Granby, 15 miles east of Red Creek. An abridged record is given 

 below. The drill started in Rochester shale, which became limey 

 below, grading apparently into the Clinton limestone. 



STRATA FEET 



Limestone i J 



Shale, with 4 inches of limestone at 102 feet depth. . . ; . . 95 



Light colored limestone, with traces of hematite i' 



Shale, with 3 inches of iron ore 4 



Limestone, basal part shaly 14 



Shale, with limestone bands 69 



Ore, oolitic Sin. 



Mottled shale , 4 



The lowest shale was not drilled through, but its base is probably 

 not more than a foot or so below the bottom of the hole. The 

 aggregate thickness is 190 feet. 



Brewerton, Onondaga co. The test hole drilled at Brewerton 

 afforded a partial Clinton section of 130 feet. 



STRATA FEET 



Olive shale, with 2 inches of fossil ore at 56 feet depth 



and thin limestone bands at intervals. . . . .* 124 



Ore, oolitic 16 in. 



Sandstone and shale 5 



From outcrops in the vicinity it is judged that the shale above 

 the ore must be at least 150 feet thick. The drill was placed near 

 the lake level and passed through 14 feet of clay before the shale 

 was reached. 



Syracuse. Two deep wells were drilled in 1884 near Syracuse. 

 One, known as the Gale well, was put down 3 miles northwest of 

 Syracuse near Onondaga lake and a little way east of the Oswego 

 canal. The altitude at the mouth of the well is given as 435 feet. 

 The record was reported by Dr F. E. Englehardt.^ The Salina 

 shales were penetrated to a depth of 525 feet, followed by the 



' Annual Report of the Superintendent of the Onondaga Salt Springs, 1884.
