Hasselborg saw seven. Although this island is very closely 

 connected with the mainland we failed to find any indication of 

 the presence of such mainland forms as Erethizon, Evotomys, 

 or Zapus, which might be expected to occur here. We remained 

 here from August 1 to 13. 



THOMAS BAY. 



An indentation on the mainland about opposite the north 

 end of Kupreanof Island. Our camp was in a little cove on the 

 west side of the south arm of the bay. This comer of the bay 

 is densely wooded down to the water's edge, but in the main 

 river valley, around a point a few hundred yards distant, were 

 broad expanses of mud flats and meadows; also stretches of 

 gravelly bottom land, sparsely covered with grass, and at times 

 evidently flooded by the stream. All these flat lands are inter- 

 sected by numerous little rivulets and sloughs, ideal feeding 

 grounds for numbers of ducks and geese. Below the meadow 

 land are vast expanses of mud flats, covered at the time of our 

 stay by flocks of thousands of small waders. The upper margins 

 of the meadows are bordered by clumps of alder. Toward the 

 base of the hills on either side the coniferous forest begins, and 

 a mile or so up the river there are a few cottonwoods. 



During the time of our stay at this point, August 13 to 23, 

 the southward migration of the water birds had fairly set in, 

 and every day throngs of ducks and waders were seen arriving 

 and departing. The land birds also were moving, but not in 

 so conspicuous a manner. 



POET SNETTISHAM. 



A deep indentation on the mainland coast about thirty miles 

 south of Juneau. We ascended the north arm of the bay some 

 fifteen miles, pitching camp on the north side of the inlet. At 

 this point a little peninsula projects out into the bay about 

 half a mile. The best collecting grounds are on the mountain 

 slopes to the eastward, but as there is no suitable camping ground 

 there, we placed our camp on the beach west of this peninsula. 

 The peninsula is densely wooded with conifers down to the 

 shore line, with abrupt rocky slopes, but in the bay to the east
