Canajoharie, Montgomery County. — In and near Canajoharie 

 there are three quarries. The oldest of them, that of A. C. & C. H. 

 Shaper, is in the western part of the town, and about 40 rods from 

 the Erie canal and the N. Y., West Shore and Buffalo railroad. The 

 quarry face has a length, approximately, of 1,000 feet, from north- 

 east to south-west, and looks north-west. The quarrying work has 

 moved south-east and south-west, and has reached in places the limits, 

 on account of buildings in the way. The dip of the beds is nearly 

 10° in places, and to the south-east. A very regular system of joints 

 runs with the strike, in a south-west direction, and at convenient 

 intervals for working. There are no south-east running joints, or 

 seams, except wide spaces apart. The bedding is true and regular, 

 and the vertical section, as given by Mr. Shaper, is :
