152 The Ottawa Naturalist. [Jan. 



It is proposed to explore the less well known parts of Canada 

 oeginning with intensive exploration at one site in each of the 

 great cultural areas that the results in the way of collections 

 and monographs may be used as standards to which to refer 

 for identification the results of future exploration obtained in 

 bordering areas where we may expect to find mixed or super- 

 imposed cultural material. 



It is planned in the near future to make a reconnaissance of 

 the plains from which there is practically no material to-day 

 available, to continue scientific exploration into the northern 

 interior of British Columbia using the Grand Trunk Pacific as 

 a base, and to do an intensive piece of excavation along the 

 St. Lawrence. Next, the shell-heaps of the Atlantic coast may 

 be examined. 



THE YELLOW BREASTED CHAT AND THE CAROLINA 



WREN IN ONTARIO. 



By W. E. Saunders, London, Ont. 



Until June, 1909, when the writer walked from Amherst - 

 burg to Blenheim in the endeavor to outline the distribution of 

 some of the more southern birds in Ontario, the only record of 

 the summer residence of the Chat in Ontario, outside of Point 

 Pelee where it breeds regularly, was that in Mcllwraith's 

 book of a pair having spent the summer near Hamilton. 



The undertaking of 1909 developed the fact, that the birds 

 were to be found in single pairs at two or three places along the 

 southern border of western Ontario, the farthest east being 

 near Renwick, which is about five miles north of Lake Erie, 

 and perhaps twenty miles north-east of Point Pelee. 



I am now permitted to record the apparent nesting of a 

 pair near London in the summer of 1911. The bird was 

 first seen by Messrs. C. Watson and M. Dale, on May 22, in a 

 wood about six miles west of London, which is a favorite haunt 

 of the Cerulean, Mourning, Golden-wing and Chestnut-sided 

 Warblers, and the Blue Gray Gnatcatcher, and, also, consequently 

 of our local ornithologists. In this wood on the early morning 

 of the 22nd of May, the above mentioned gentlemen heard the 

 call of the Chat ; fortunately they had both visited Point Pelee 

 with the writer earlier in the month when they became acquainted 

 with this bird for the first time, so that when the note was heard, 

 they realized the prospect ahead of them, and therefore they 

 stuck to the job until the bird was well seen. Since then they 

 have visited the localitv four times, the last of which was on
