V. Foulke Fiord, lat. 78° 18', July 28, 29, 1875. 



This fiord is well known as the winter-quarters of Dr. Hayes, 

 18G0-61. Its sides are from one to two miles apart, rising to 

 a plateau 1500 to 2000 feet in height. The rock is chiefly red 

 gneiss, surmounted here and there, as at the upper end of the 

 glacier, by basalt, traps, and sandstone, which in many cases has 

 been eroded and given rise to a fertile valley at the head of the 

 fionh Along this valley to Alida Lake, at the foot of Brother 

 John's Glacier, is about one mile.. A hard day's climbin" brought 

 a party of us up the north side of the glacier, across the mer-de- 

 glace at its head and down by its southern side. This walk gave 

 me an impression of greater life and growth than any other in the 

 Arctic regions ; the southern side of the valley is the head- quarters 

 ot myriads of little auks, and the result is a richness of soil under 

 tlie bird cliffs which leads to a rank and rapid vegetation. Here 

 brst i iound the pretty and sweet-scented Hesperis Pallasii ; typical 

 Dychms apelala and ihyns octopetala also grow here in company with 

 their commoner and more southern forms, Lychnis affinis and 

 Bryas mtegnjuha. Upon the plateau, from twelve hundred to fifteen 

 hundred feet I gathered also, for the first time, Samfraga flaaellaris ; 

 it appeared o be confined here to high levels. At this station also, 

 in the neighbourhood of Point Jensen, Dr. Coppinger was fortunate
