bank on the shore of Oxford Lake, near Oxford House, June 
30th. Several colonies were seen on Hayes River, a few miles 
above York Factory. (4. A. Prebles.) This species was found 
everywhere along the 49th parallel where there were cut banks 
suitable for breeding sites for the digging of holes in which the

reached there June 11th and began breeding in the cut banks of 
the creek; dug out two nests, but only obtained three eggs, one

was first noticed at Old Wives’ Creek, Assa., and afterwards on
