house was built. Common Te.rns were flying about, Spotted 

 Sandpipers teetered on the rocks just off shore, and in the 

 trees we found Northern Flickers, Kingbirds, Wood Pewees. 

 Red-winged Blackbirds, Bronzed Crackles, Goldfinches, Song 

 Sparrows, Purple Martins, Red-eyed Vireos, and House 

 Wrens, while Bank Swallows were flying about in consider- 

 able numbers. The only notable bird here was a three-legged 

 chicken, which we were obliged to admire. 



North Harbor Island, August 7 and 8, 1901.— We reached 

 this island just at nightfall, and went into camp. It is like 

 the Old Hen in standing up out of the water, but is about 

 half as high, with a gravelly beach at its south end. Creat 

 glacial grooves mark where the ice scoured it down in cross- 

 ing it at nearly right angles. It is about five rods wide by 

 135 long, extending in a northerly and southerly direction. 

 Nearly its whole surface is covered with trees and bushes, 

 and the usual grasses and other annuals cover the ground 

 under trees and bushes. The ground is also covered with 

 snails (Helix albolabris ?), and the dead shejls occur in great 

 numbers in the humus. We saw Purple Martins coming toward 

 the island in considerable numbers, and they finally settled 

 for the night in the large tree which marks the south end of 

 the island. There were enough of them to fill the tree. As we 

 prepared for the night we were surprised to see the Common 

 Terns settling among the trees, alighting on the branches, 

 where they apparently remained roosting all night. Their 

 nests were everywhere about the island, except in the densest 

 undergrowth. A count of the nests was impossible, but there 

 seemed to be fully as many birds about as at Big Chicken. The 

 birds noted were Common Tern, Black Tern, Great Blue 

 Heron, Spotted Sandpiper, Kingbird, Wood Pewee, Red- 

 winged Blackbird, Bronzed Crackle, Goldfinch, Purple Mar- 

 tin, Bank Swallow, Cedar Waxwing, Red-eyed Vireo, Caro- 

 lina Wren singing. The Wren was a great surprise. We 

 left the island to visit East Sister, in the middle of the day, 

 and returned to pick up the camp equipment. We finally left 

 the island about 3 o'clock p. m.
