Annual Field Day. 427 
Miss Smaile obtained the prize for the largest collection of 
unnamed plants, having fifty-five species. 
Mr. H. H. Lyman acted as leader in entomology, and 
very large collections were obtained by several gentlemen. 
Mr. Winn secured the first prize for his collection of 104 
species, while the second prize was awarded to Mr. Hausen. 
Dr, Adams, the leader of the geological section, at the 
outset explained the general geological structure of the 
whole district passed over since leaving Montreal, illustrat- 
ing his remarks by diagrams in coloured chalks sketched 
on a large slab which was found by the road side. He 
stated that although the district about Ste. Agathe was 
most interesting as showing geological structure, the un- 
derlying rock was very uniform in character and did not 
furnish many specimens to the collector. The rock, he 
stated, was all anorthosite, composed almost exclusively of 
a lime-soda feldspar, and had been erupted through the true 
Laurentian rocks forming a great area of 990 square miles 
in extent. Ste. Agathe was situated about the centre of 
this area. 
The effects of the:great pressure to which these rocks 
had been subjected and which had served to crush them in 
a peculiar manner, were pointed out, also the effect of the 
ice, which had ground them down in the last glacial age, 
as well as the numerous boulders of rocks not found in the 
vicinity which had been carried to the locality by the ice 
during this glacial period. 
At 5 p.m., there was another gathering of the villagers 
at the station to say good-bye. The thanks of the Society 
were expressed in two or three short speeches, and the train 
started homeward amid the cheers of both the villagers 
and their visitors. After a fast run home, which was 
enjoyed as much as the trip out, the Windsor station 
was reached without further incident. There a vote of 
thanks, with three hearty cheers, was given to Mr. Mc. 
Nichol and officers of the C.P.R. for the kindly manner in 
which the Society had been treated. |
