80 The Ottawa Naturalist. [July 



spected by Mr. Groh, who proved the best climber, and found it 

 to contain two eggs. The female only left the nest, noiselessly, 

 when the climber was half-way up. The nest was about two 

 feet in diameter, the inner cup about 8 inches, lined with pine 

 twigs, stripes of birch and soft inner bark and down of the bird 

 itself. They use the same nest over and over again, but each 

 year decorate it with green branches of pine, whereby it can be 

 seen at once from below whether it is a used hawk's nest or not. 



Insects were beginning to appear in numbers but nothing 

 of special rarity was met with during the afternoon. Mr. Arthur . 

 Gibson noted a few nests of the American Tent Caterpillar. 

 These were just beginning to assume a conspicuous size. A few 

 speciinens of the small early spring blue butterfly were seen, 

 and one or two of the Pure White. Some beetles and other 

 insects were collected by the entomologists present from under 

 the bark, etc., and a small collection of spiders was made.

Chelsea, Que. 



The general excursion to Chelsea was held on Saturday, 

 June 5th. 



Owing to the uncertain state of the weather, the attendance 

 was not as large as usual. However, despite the clouds and 

 humiditv, among those present were Mr. Attwood, Rev. Mr. 

 Eifrig, Mr. W. J. Wilson, Mr. and Mrs. J. H. Putman, Mr. Mc- 

 Gillivray, Mr. R. H. Campbell, Miss Christie, Mr. Shannon, Miss 

 Matthews, Mr. H. S. Winchester, together with a number of 

 Normal lady students in charge of Mr. and Mrs. Thos. Brown. 



On reaching ChelSea the members were divided into groups. 

 Mr. Wilson led the geological branch, while Mr. Attwood and 

 Mr. Eifrig jointly took charge of the botanists and ornithologists. 

 After making a tour through the woods, visiting Gilmour Island 

 and rapids, the second party moved along the west bank of the 

 Gatineau River, till the old boom house was reached, ascended 

 the hill, recrossed into the woods and finally reached the railway, 

 near the Chelsea summit, after gathering flowers and studying 

 the birds, under direction of the leaders, as thev passed along. 



The geological party examined the rock cuttings along 

 the railroad. A good exposure of garnetiferous gneiss is seen 

 a short distance north of Chelsea Station. The foliation is 

 well shown, the rock being smoothed and polished by ice 

 action. The striae run nearly, south at this point. Resting 

 on the gneiss there is a good section of the pleistocene deposits. 

 Boulder clay with striated boulders lies directly on the rock, next 

 there is a mass of Leda clay and on top of this the Saxicava sand. 

 These deposits vary from almost nothing to twenty or thirty feet
