of mountains extending northwesterly to the opening which I haA-e called the Great 

 Gateway.' * * * 



I visited that phenomenon; I mounted it, and went around it also. It is a mount 

 of marine fossils in limestone, half a mile long, and over a hundred feet high [340 

 feet aneroid, according to Porter]. * » * Xhe debris of the fossils begins at or 

 near the top of the mount, falling at such an angle as broken stoue from a mountain 

 abvaysmake, an inclination of about 40°. Above the talus, or heap of broken stones, 

 is a mass of fossils iu limestone, strata-like. A smaller mount of the same char- 

 acter is close by, but all 

 iu debris. It seems to 

 have been divided from 

 the main mount by the 

 rushing down of waters 

 from the mouutains be- 

 hind. A small stream 

 comes down the moun- 

 tains, passes along, and 

 finally makes its way out 

 between the two fossil 

 mounts. This is also in- 

 dicated in the course of 

 this stream, as an acre 

 or more of the plain is 

 covered several feet in 

 depth with the washed- 

 dowu debris of fossils. 

 * * * The top of Sil- 

 liman's Fossil Mount is 

 covered with boulders 



and grass. Even Avhen close to the small mouot it looks like sand, but on examina- 

 tion it is fine broken limestone aud fossils. - 



Mr. E. W, Porter, who visited Sillimau's Fossil Mouut in August, 

 1897, described it to the writer as follows : 



On board S. S. Hope,

My Dear Sir : In accordance with your request, I take pleasure in handing to 

 you the following notes on Silliman's Fossil Mount (Hall's) of Frobisher Bay, Baffin 

 Land. They are ^ery meager — the results of only a few hours' visit to this forma- 

 tion, as I had intended to give the place a more thorough search next year. 



Silliman's Fossil Mount lies at the head of Frobisher Bay, some 3 miles south of the 

 Jordan River and about 1 mile from tide water. It lies close against the mountains 

 of Meta Incognita [apparently uu conformably] , is abont 1,000 yards long and 340 feet 

 high (aneroid ; not 100 feet, as given by Hall), general direction northwest and south- 

 east. The fossils were taken from the talus slopes, the bed of the brook flowing 

 at the base of the mount, in the limestone near the summit, and on the top itself. 



At its northern end there is a smaller mount of lesser height. The mount forms 

 a striking feature of the landscape, aud is composed of limestone, disintegrated to 

 such an extent that the talus reaches nearly to the summit, which is very flat and 

 composed of the ledge itself. This limestone ledge of nearly horizontal beds out-
