was seen on the shore of Great Central Lake, August 18, the only 

 individual seen anywhere except along swiftly rushing streams. 



Vancouver Island, with its innumerable streams, large and 

 small, affords peculiarly congenial surroundings to the dipper, 

 and it is abundant and of general distribution. 



Ten specimens were collected (nos. 16476-1648")), three adults 

 and seven in juvenal plumage.

Apparently restricted to the east side of the island. Although 

 occurring in numbers at the various points visited in the vicinity 

 of Parksville and Errington, it was entirely absent in Alberni 

 Valley, some thirty miles to the westward, a region not obviously 

 different in its characteristics. 



Young, out of the nest, were taken at French Creek May 19. 

 and later. Probably in some cases two broods are raised in a 

 summer, as young birds at about the same stage of development 

 were collected in the last week of May and early in September. 

 The birds were quite common at Errington during the first two 

 weeks in September, but by the end of the month nearly all 

 had disappeared. 



Eighteen specimens were collected (nos. 16486-16503), eight 

 breeding adults, seven in juvenal plumage, and two immatures 

 and one adult in fresh winter plumage.

 Fairly abundant at Parksville and neighboring points the 

 last week in April and during May. Seen in Alberni at various 

 times in June, and also in the Beaver Creek Valley. Just below 

 our camp at the latter point a nest was found in a huge, dead 

 stub by the roadside. On June 9 it contained young birds, as 

 was evident from the sounds, but the entrance was too small and 

 the hole too deep to admit of further investigation. The species 

 was not seen at Nootka Sound, nor in the higher mountains we 

 visited. Thev must leave for the south at a rather early date in
