 a better and more efficient lighting with a south exposure

Monday, September 2. — As many as half the members of 

 the club were absent on the excursion to the Muskoka lakes, 

 but the usual meeting was held at 9 a. m. in the biological 

 room, Prof. Bessey acting as president and Prof. Arthur as

The "treasurer's report was read, showing a deficit of over 

 four dollars. After some discussion it was laid on the table 



tor subsequent action. 



Mrs. Henrietta L. T. Wolcott desired to learn if the amber- 

 colored choke-cherry occurred in Canada, as she had been 

 told that it did. She reported the destruction, during some 

 street improvements, of the original trees with amber-colored 

 fruit in Dedham, Mass., which the club had heard about at 

 former meetings, and which Dr. Sereno Watson had thought 

 worthy of being described as a distinct variety. No one was 

 able to give the information desired, but it was the opinion, 

 especially of Mr. Macoun, that no such variety was known 



to exist in Canada. 



Mr. W. H. Seaman exhibited a number of species ot in- 

 teresting plants gathered in the vicinity of Toronto, and also 

 a convenient portable plant press. Quite an extended dis- 

 cussion arose on different forms of presses and methods ot 

 collecting. Mr. Macoun said that he and his son together 

 had collected as many as 20,000 specimens in a season in 

 connection with the Canadian survey. They use presses 

 with board sides and stout straps, containing about twent\ 

 sheets of the usual drving papers. To secure good speci- 

 mens in wet weather, when in camp, the dryers are held be- 

 fore the camp fire one by one until a pile of hot dryeis is 

 secured to which the plants are transferred from the hanci 

 press. Other papers are similarly heated, and the plants 

 again transferred. Usually three transfers are enough o 

 fully dry all but the thickest specimens, so that the plants 

 collected in the forenoon may be dried during the afternoon. 



The members who participated in the excursion to tin- 

 lakes met at the usual hour of 9 a. m. in the upper cabin ot
