28 The Ottawa Naturalist. [May 



These, the only large trees on the island, prove a great attraction 

 to warblers, sparrows and other small migrants. 



Along the north shore of the sandbar, fringed by rushes and 

 Phragmites for the greater part of its length, many varieties 

 of plants find conditions suitable to their development. Several 

 species of Solidago, Lobeliaceae, Gerardia purpurea, Turtlehead 

 and many beautiful Graminace-e. During May and June the 

 sand is yellow with the blossoms of Potentilla anserina. 



The wide stretch of bog in the south-west corner of Ash- 

 bridges Bay is cut up by a chain of shallow weedy lagoons, known 

 by the local sportsmen as " Knockem Pond", "The Deep Hole" 

 and "The Lilyweed Pond." The waste oil deposited in the bay 

 by the gas works has killed off a number of the less hardy water 

 plants, but such species as Pickerel weed, Arrow-head and three 

 varieties of Nymphaea are still abundant. Florida Gallinules, 

 American and Least Bitterns, Sora and Virginia Rails, Long-b. 

 Marsh Wrens, Red-winged Blackbirds, Swamp Sparrows, and 

 occasionally Coots, Red-billed Grebe and Blue-winged Teal 

 breed in the bog. The Gallinules, Rails and the more wary 

 species choose the less accessible places where the vegetation is 

 too dense to allow the passage of a canoe and the bottom too 

 treacherous to admit of wading. 



The fallowing records were made between Januarv 1st and 

 July 10th, 1910: 



Holboell's Grebe. One seen on April 2nd, feeding in 

 "Knockem Pond." It allowed a canoe to approach within sixty 

 yards before taking flight. May 2nd, one seen in the "Beach 

 Pond". May 3rd, two seen in Toronto Bay, feeding along the 

 island shore. 



Horned Grebe. March 5th, three seen in the lake swim- 

 ming close to the ice banks on the shore. No more were seen 

 until April 16th. From that date until April 23rd thev were 

 fairly plentiful in "Knockem Pond" and "The Deep Hole." 

 On April 17th three were seen asleep with their heads on their 

 backs. 



Red-billed Grebe. One seen in "Knockem Pond" on 

 March 31st. Two on April 2nd. On April 9th and 10th they 

 were quite numerous. None were seen after April 10th. In 

 former years several pairs always nested in the marsh. 



Loon. May 13th, seven were seen swimming up the lake 

 not far from the shore. Until the end of May two or more were 

 seen daily. The last spring record was made on June 12th, 

 when a single bird flew over the beach. 



Glaucous Gull. May 30th, one seen on the sandbar among 

 a flock of Herring Gulls. 



Herring Gull. During January and February single birds
