An Expedition down the Begh-ula. 29 



vicinity is given by Abbe" Petitot, in the Bulletin de la 

 Societe de G-eographie, (Yol. X., p. 173). The map accom- 

 panying the article of Abbe* Petitot, is the best available of 

 the region in question and may be consulted in following 

 Mr. MacFarlane's route. His course was northward and 

 eastward from Fort Good Hope to the Lockhart River, 

 thence down that river and the Anderson (of which it is a 

 tributary), nearly to the Arctic coast, where he was turned 

 back by the Eskimo. He then returned southward by land, 

 and after examining an additional portion of the Anderson, 

 above the mouth of the Lockhart, together with another 

 tributary named the Ross, he struck across in a westward 

 direction to the Peau de Lievre or Hare-skin River by 

 which he returned to Fort Good Hope. 



Mr. MacFarlane has also furnished me with an additional 

 short general description of the Barren Grounds, to the east 

 of the Anderson River, between that river and Franklin 

 Bay, crossed by him four times in 1862 to 1865 for the 

 purpose of collecting birds, eggs, etc., for the Smithsonian 

 Institution. 



Some fossils collected by Mr. MacFarlane in the course of 

 these expeditions are described by Meek in his paper, pub- 

 lished in the Transactions of the Chicago Academy of Science 

 (Yol. I., p. 15). These are referred to in my Notes to 

 Accompany a Geological Map of the Northern Portion of the 

 Dominion of Canada, (Annual Report Geol. Surv. Can., 1886., 

 p. 30r,) but Mr. MacFarlane's valuable observations were 

 not then available for reference in connection with the 

 compilation of the map. It would now appear from them, 

 that between the Mackenzie River and Franklin Bay, the 

 Devonian and probably also the Cretaceous rocks, came 

 further south than was supposed, covering a portion of the 

 region coloured as Archaean on the map.
