Stone Bay, where upwards of 100 pairs had nested, on July 25. 

 On the precipitous face of a high rocky point, which is washed 

 by the waters of Artillery Lake, called the Beaver Lodge, a con- 

 siderable colony was noted on August 1, and a male bird, prob- 

 ably belonging to this colony, was collected at our camp at the 

 tree limit on August 3. This was the last date recorded. Dur- 

 ing our ascent of the Athabaska in October, we saw many nests, 

 now deserted and in ruins, on the limestone cliffs near Fort 

 McKay. 



Hirundo erythrogastra Boddaert. Barn Swallow. 



A few barn swallows were seen at Fort Smith on June 16. 

 Our only record otherwise was of a small colony, undoubtedly 

 nesting on the cliffs, near the eastern extremity of Caribou 

 Island in the eastern part of Great Slave Lake, July 21. 



Iridoprocne bicohr (Vieillot). Tree Swallow. 



The white-bellied swallow was noted at Athabaska Landing 

 on May 15, was common on May 16, and during our descent 

 of the river was seen near La Biche River, May 18 and 19 ; above 

 Brule" Rapid on May 25, and near Fort McKay on May 30, 

 when it was very common. We found it nesting in the country 

 west of the mouth of Salt River, June 25 to 27. It was noted 

 also at Fort Smith on June 28, and was seen on Little Buffalo 

 River on July 7, and on the Nyarling on July 10. The northern- 

 most point recorded was Fort Resolution, where we observed 

 it, July 14 and 16. 



Riparia riparia (Linn.). Bank Swallow. 



This widely distributed swallow was noted on the Athabaska, 

 below Grand Rapid, on May 25, and near Fort McKay on May 

 30. Observed also at Fort Smith on June 16 and 22, and daily, 

 June 28 to July 3. A nesting colony was seen at this point on 

 June 22. While we were descending the Slave, between Salt 

 River and Grand Devour, on July 5, we noted many of the birds, 

 and many nesting colonies, now of course deserted, were seen
