[Nov. 



with fledglings, one may hear the migratory "tsip" of earlier 

 broods preparing to leave the woods. This is done gradually; 

 by the middle of August small flocks are to be found in thickets 

 and hedges of the more open country. From then on the deeper 

 woods become very quiet, though there are always a few birds 

 detained with late broods, even after the Wood Peewee's note 

 is no longer heard. I have heard a White-throat in full song, in 

 its breeding haunts, as late as September 2 7th (1908), but this 

 is unusual. During September and October they are to be 

 found chiefly flocking with other sparrows in the hedges of the 

 open country, in the outskirts of woods, along river banks and 

 in city gardens. In these situations they often utter their alarm 

 notes, but I have yet to hear a White-throat singing in the open 

 country. 



By the middle of October the bulk have departed, and 

 toward the end of the month practically all have gone; though 

 I have one exceptional record, November 22nd, 1908, when I 

 secured an immature bird and saw another. 



My observations on the White-throated Sparrow were made 

 in the counties of Laval, Jacques Cartier, Laprairie, Terrebonne 

 and Compton, Province of Quebec. 



FIELD NOTES OF CANADIAN BOTANY. II. 



By Edward L. Greene. 



A year has passed, and somewhat more, since the first in- 

 stalment of these notes was published. That paper, as may be 

 seen by reference to it in the issue of The Naturalist for 

 September of last year, consisted of notes on the vegetation of a 

 tamarack marsh at Strathroy, western Ontario; and since I had 

 not completed my account of the region as a whole, I may as well 

 resume at the point where I left off. 



I had descended to the marsh by a well-beaten path, evidently 

 the trail of children and others of the Strathroy villagers who 

 naturally resort to the place to gather its choice floral treasures 

 in spring and summer. I left the spot from another side where 

 there was no path; and on ascending to the slightly higher 

 ground of the low hills that shut in the marsh on two sides, I 

 encountered a low sumach thicket which, although it was the 

 middle of June, was not yet in foliage. The sumachs are all late 

 in coming into leaf, and this colony was at that stage when the 

 new shoots are a few inches long, and the leaves barely beginning 

 to unfold. There was that in the first near view of these shrubs, 

 just emerging from their winter condition, their branches still
