152 The Ottawa Naturalist. [September 



is not merely a United States organization. -It especially includes that 

 potent and ambitious neighbor of ours to the northward that owns 

 more than 3,000,000 square miles, or a full half of the North American continent. 

 The association always counts with all confidence on its Canadian contingent. You 

 can hear this afternoon an address [rom the honored Canadian vice-president of one 

 of our sections. 



In the section of Geology and Geography,the Vice-President 

 and Chairman, Mr. Whiteaves, gave an address "on the 

 Devonian system in Canada," which will appear "in extenso" in 

 the next number of Scioice and in ^the Transactions of the 

 Association. 



Mr. F. B. Taylor's paper on " The Gait Moraine and Assoc- 

 iated Drainage " is an important contribution to our knowledge 

 of the glacial geology of southern Ontario. And, in the same 

 section (Geology and Geography), Miss Mary A. Fleming read 

 a paper on the " Pot Holes of Foster's Flats, now called Niagara 

 Glen," on the Canadian side of the Niagara River. 



Besides a paper on "the Arboretum and Botanic Garden of 

 the Central Experimental Farm, Ottawa," read before the 

 Botanical Club of the Association, Dr. Saunders read two 

 papers before the Botanical Section, one entitled " The Breeding 

 of Apples for the Northwest Plains," and the other " Useful 

 Trees and Shrubs for the Northwest Plains of Canada." 



In the section of Physics, Mr. F. A. Saunders read a paper 

 entitled a " Bolometrical Study of the Radiation of an Abso- 

 lute Black Body." 



The Botanical Section devoted^one day (Wednesday, call- 

 ed "Sullivant Day" in the programme) to a commemoration of 

 the scientific labours of the late William S. Sullivant and Leo 

 Lesquereux, who lived at Columbus, two of the earliest students 

 of and authorities on North American mosses and hepaticae. 

 The members of the Geological Section united with the Geo- 

 logical Society of America in giving one day, (Thursday) to an 

 examination of the glacial phenomena in the neighborhood of 

 Lancaster. 



The weather was everything that could be desired, the 

 general attendance at the meetings fairly large, the excursions 

 both instructive and enjo}'able, and the social functions brilliant 

 and most successful.
