In 1S59, James Richardsonf made a geological examination of the 

 Gaspe peninsula, and observed two terraces in the drift to the west of 

 Trois Pistoles river, at 130 and 300 feet, respectively, above the sea, 

 and another at the mouth of the Matanne. at the height of 50 feet. 

 Stratified clay occurs at the head of lake Matapedia, 480i'eet above the 

 sea and near the outlet at the height of about 530 feet. Marine testacoa 

 occur in the terrace on the east side of the Matanne river at the height 

 of 50 feet above the sea; about two miles west of the Metis river, at 

 the height of 130 feet, and eight miles up the Metis river, at 245 feet 

 above the sea. At the St. Anne river there are five or six terraces in 

 a height of 25 feet, abounding in fragments of marine shells. Grooves 

 and scratches were observed a half mile below Trois Pistoles church, 

 60 feet above the sea, bearing S. 32 deg. E., and on the Kempt road, 

 two miles from Lake Matapedia, 630 feet above the sea, and bearing S. 

 80 deg. E. 



W. E. LoganJ explored the river Rouge, a branch of the Ottawa, to 

 the Iroquois Chute, about fifty miles from the mouth. He found an 

 undisturbed deposit of clay on the left bank of the river, on the fourth 

 range of Grenville, 280 feet above Lake St. Peter. In the rear of Gren- 

 ville and front of Harrington, not far east of the Rouge, there spreads 

 out a flat surface of several hundred acres in extent, which is under- 

 laid by clay, and has a height of about 500 feet above Lake St. Peter. 

 The plain of the three mountains has an elevation above the ordinary 

 sunamer level of the river, of about 30 teet, and above Lake St. Peter of
