It was found beneath the fossil bones of the JHegalonyx jeff'ersoni, and 

 Ilastodon giganteum. 



In 1847, W. E. Log-an* found marine testacea along- the valle}' of 

 the Ottawa, in the clays and sands that form the superficial deposits. 

 These deposits cover the whole valle}"^ of the south Petite Nation and 

 its tributaries ; and occur in Templeton, Hull, Nepean, Packeiiham^ 

 and Fitzro}', to the month of the Mississippi and Madawaska. They 

 were found in Fitzroy, 330 feet above the level of the sea, and in 

 Nepean, 410 feet above the sea, where Saxicava rtigosa occurs in the 

 gravel. At the mouth of Gattineau, near B3-town, not onh^ marine 

 shells were discovered, but in nodules of indurated clay the JIaUotus 

 villosKS, or common capeliug, a small fish, which still frequents the 

 shores of the Gulf of St. Lawrence, was obtained in vast numbers. 



Grooves and scratches on the surfaces of the rocks were met with 

 on the Gattineau, between Farmer's and Blasdell's mills, having- a direc- 

 tion S. 36° E ; on Glen's creek in Packenham, N. and S. ; on the Allu- 

 mettes Lake, at Montgomer^-'s clearing, S. 25° E. The shores 

 of Lake Temiscamang, which is long and narrow, and has banks 

 bold and rocky, rise into hills 200 to 400, and sometimes 

 500 feet above its surface. The general valle^^ of the lake thus 

 bounded presents several gentle turns, the directions connected 

 with two of which, reaching down to the mouth of the Keepawa river 

 (35 miles), are 158°, 191°, 156°, numbering the degrees from north 

 as zero around by east. The parallel grooves in these reaches of the 

 valley turn precisely' with them, as if the bounds of the valley had 

 been the guiding cause of their bearings, and they are registered on 

 various rounded and polished surfaces projecting into the lake, and 

 sometimes rising to 30 and 40 feet over its level. These projecting 

 points did not deflect the grooved lines in the slighest degree. In one 

 case, where the projecting point is 35 feet high, the furrows were ob- 

 served to move over it without an}- deflection whatever ; so that, what- 

 ever bod\', moving downward in the talley, may have caused the 

 grooves, it was not deflected by meeting an obstacle 35 feet higher 

 than the surface of the lake. On che top of this projecting point, 

 the grooves are crossed by another parallel set at an angle of 15°. 



The Compan^^'s Post stands on a point on the east side, which cuts 

 the lake nearly in two, at about 18 miles from the head, and it is oppo- 

 site a less prominent point on the other side. These points approach 

 to within a quarter of a mile of one another. Both are composed of ^
