in layers of varying thickness. Some of these layers illustrate 

 "false bedding;" the layers being composed of a number of 

 laminae lying at a steep angle, while the main beds are horizontal. 

 It was pointed out that the tilted layers were probably laid 

 down on a sloping bank by a swift current, and that this was 

 followed by a period of still water, wdien the horizontal bed was 

 deposited on top. It is interesting to note that this sand con- 

 tains marine shells, indicating that an arm of the sea invaded 

 this area when it was deposited. Attention was directed to the 

 cut terraces surrounding the lake, and also to the gully cut by 

 the present outlet, which has reduced the water to its present 

 level. 



After Mr. Wilson's interesting and instructive talk, Mr. 

 Kingston gave a short account of his afternoon's observations 

 in ornithology. The following is a list of the birds that had been 

 noted: 



Night hawk, Chimney Swift, Kingbird, Wood Pewee, Crested 

 Flycatcher, Least Flycatcher, Red-winged Blackbird, Cowbird 

 (female). Meadow Lark, Baltimore Oriole, Goldfinch, Song 

 Sparrow, Swamp Sparrow, White-throated Sparrow, Vesper 

 Sparrow, Rose-breasted Grosbeak, Bank Swallow (nesting), 

 Yellow Warbler, Black-throated Blue Warbler, American Red- 

 start, Maryland Yellow-throat, Oven Bird, Wilson Thrush. 



Several interesting points were brought out concerning the 

 different birds, particular mention being made of the Cowbird, 

 and her lazy habit of depositing her eggs in the nests of smaller 

 birds. A last year's nest of a Red-winged Blackbird was found 

 by one of the party and handed around for inspection. Notices 

 having been given out about the excursion to Macdonald College, 

 etc., the party started for home, everyone feeling, I am sure, 

 that the afternoon had been spent to some purpose, and that a 

 great deal of knowledge had been acquired in a very delightful 

 way.
