104J Report on Building Stone of New York. 



of the same road. It is now owned by Hugh Behan. An area of 

 500 feet in length, north-west to south-east and half as B [wide nearly, 

 has been gone over, and the stone removed to a depth of from five to 

 eleven feet. The covering on the rock is nowhere more than one foot 

 thick. The strata dip 7° to 8° easterly, The rock is divided verti- 

 cally by one marked, smooth joint plane, which runs south 65° east ; 

 and by another whose course is north 15° east. They occur at 

 intervals of 18 to 20 feet apart, and are very regular. The stone is 

 of a bluish-black color, hard and semi-crystalline. On weathering it 

 fades to a gray shade. But unless well selected it is apt to show clay 

 seams. A vertical section ot the strata at the deepest part of the 

 quarry shows : weathered rock, one foot ; then the blue limestone in 

 beds, two feet, one foot, two feet, four and a half feet and two feet 

 thick, respectively, making in all a thickness of 11 feet 6 inches. 

 There is very little water, and no pumping is necessary. Some of 

 the stone from the quarry is used for making lime. A fine 

 example of this stone is seen in the Peristrome Presbyterian church 

 building in Plattsburgh. 



On the east of the Beekmantown road, and north-east of the Piatt 

 quarry, there is an excavation 100 yards x 70 yards, from which a 

 large amount of stone has been taken. At this place the dip of the 

 strata is very gentle eastward. The rock here is divided by a regular 

 joint, which dips 75° north 5° east, and runs south 85° east, and by 

 a second, running north* 15° east, and nearly vertical. At this quarry 

 the courses or beds are : top, two feet thick, second, two and a half 

 feet, and bottom three feet. It is bluish-black, excepting on weath- 

 ered surfaces, which are gray. This quarry belongs to Mrs. Mc- 

 Cready, and is worked occasionally by Peter Lezotte, of Plattsburgh. 

 The stone has a good reputation for heavy work, for which it is 

 admirably suited. It has been used by the D. & H. Canal Company 

 in some of their bridge work on the N. Y. & Canada Railroad line. 



One-fourth of a mile north, and on the same side of the road, is 

 what is known as the Fitzpatrick quarry, a small opening, which is 

 worked a part of the year only. Ihe greater part of the product is 

 used as furnace flux, but some of the stone is gray and of a crystalline 

 structure, and when polished merits the name of marble. 



North of the latter is Morrison's quarry, in a gray limestone. It 

 furnished most of the stone for the St. John's Roman Catholic church 

 in Plattsburgh, and a part of that used in the Peristrome Presbyterian 

 church.
