ANCHOK-STONES.

by Mr. John B. Wiggins, of Waverly, Tioga County, New York. Fig. 341 

 shows the form of one of them. It is made of a flattish boulder of fine-grained 

 sandstone, more than three inches in thickness. The groove, which runs parallel 

 with the longer sides of the boiUder, is over an inch deep on the face shown in 

 the illustration, and ground out its whole length, but much shallower on the 

 opposite one, and there it seems to be a natural, yet artificially modified, depres- 

 sion in the boulder. This specimen, which weighs eighteen pounds and three- 

 quarters, was discovered in August, 1881, near the middle of the Susquehanna 

 River, in the neighborhood of Sayre, Bradford County, Pennsylvania, by Mr. 

 Benjamin F. Coolbaugh, while engaged with a party in spearing fish. Seeing 

 the object by the light of the torch, in passing over the place where it lay, be 

 returned and secured it.

The other specimen, somewhat smaller, and weighing not more than sixteen 

 pounds and a half, is almost identical in shape with the one just described, and 

 consists of the same kind of fine-grained sandstone. It was also obtained in 

 1881 by Mr. Coolbaugh, at Sayre, where it came to light while laborers, em- 

 ployed by a railroad-company, were clearing away the ground with a steam- 

 shovel, to prepare a place for erecting machine-shops. The stone lay imbedded 

 in gravel and sand ten feet below the surface. 



Fig. 342 on the following page, representing an anchor-stone of another 

 form, is made after a drawing sent to me by its owner, Dr. J. F. Snyder, men- 

 tioned on page 126 of this work. It was found, some years ago, in the bed of the
