general acceptance. Various authors who had not seen the original 

 specimens, or made a special study of any allied forms, seem to have 

 accepted without hesitation the striking adaptive characters of the 

 posterior limbs as the key to real affinities, and likewise put this 

 opinion on record. The compilers of such knowledge followed suit, 

 and before long the Ratite affinities of Hesperornis were seldom 

 alluded to in scientific literature. 



Several times I was much tempted to set the matter right as far 

 as possible b}^ reminding the critics that they had overlooked 

 important points in the argument^ and that new evidence brought 

 to liglit, although not conclusive, tended to support my original 

 conclusion that Hesperornis was essentially a swimming ostrich, 

 while its resemblance to modern diving birds was based upon 

 adaptive characters. On reflection, however, I concluded that such 

 a statement would doubtless lead to useless discussion, especially on 

 the part of those who had no new facts to offer, and, having myself 

 more important work on hand, I remained silent, leaving to future 

 discoveries the final decision of the question at issue. 



It is an interesting fact that this decision is now on record. 

 A quarter of a century after the discovery of Hesperornis, and 

 a decade and a half after its biography was written in the 

 " Odontornithes," its true affinities, as recorded in that volume, 

 are now confirmed beyond dispute. In the same region where the 

 type-specimen was discovered, a remarkably perfect Hesperornis, with 

 feathers in place, has been found, and these feathers correspond 

 with the typical plumage of an ostricli.^

n^HE rocks to which the following facts relate outcrop on both the 

 JL eastern and western shores of Lake Temiscaming immediately 

 north of the "Old Fort" Narrows on the upper Ottawa river, the 

 deep channel of which forms the boundary-line between the 

 Provinces of Ontario and Quebec. 



On the eastern side of the lake the granite forms a strip along the 

 shore half a mile wide, extending from a point three-quarters of a mile 

 north of "The Narrows" on wliich is situated the now abandoned 

 Fort Temiscaming, a fur-trading post belonging to the Hudson Bay 

 Company, to the steamboat wharf near the village of Bale des Peres. 

 It also constitutes the rocky promontory known as Wine Point to 

 the west of Bale des Peres, extending inland in a north-easterly 

 direction for about one mile and a quarter. On the western side of 

 the lake the first outcrop is noticed about half a mile west of " The 

 Narrows," continuing along the shore for about four miles as far as
