REPORT OF THE SOCIETY 81 



need not exceed 10c. for the negative and 10c. for each positive, which 

 would mean 40c. for each slide, $4 for 10; S40 for 100; S400 for 1,000. There 

 is here nothing exorbitant, surely. 



In practice this is what I should advise: 



That there be a member or a committee intrusted with collecting 

 prints, drawings, photographs; in a word, whatever may furnish a good 

 subject for a slide. The members of the Association would be invited to 

 co-operate in furnishing drawings and pho'.ographs of their experiments 

 and observations. 



That this member or committee arrange with some photographer, 

 or other person, one or several, to have the negatives and positives made. 

 Really skillful amateurs could often be found ready to render very appre- 

 ciable services and the same may be said of professors of sciences in many 

 colleges. Many institutions and professors would gladly loan negatives. 



The slides would bear a number and title and would be classified in 

 numerical order. This would prevent much misunderstanding and save 

 time in correspondence. After a time a complete list would be published, 

 then, every six months or every year, according to the work accomplished, 

 a supplement would be issued. 



B. Lectures 



Not alone would the members of the Society be called upon to give 

 lectures, but all friends of plants, all professors and teachers. The slides 

 being at the disposal of all, and the lantern being a means of instruction 

 greatly enjoyed by the young, many teachers would avail themselves of 

 this means to interest their pupils and in order to impart instruction to these 

 would study up the matter themselves. 



\\'hat would be the role of the members? Each one could, according 

 to his will, according to circumstances, give lectures, and it is my opinion 

 that they would often be invited, since the professors of all the schools 

 would know their willingness to lecture. But they could do yet more, 

 and better: prepare lectures at least in outline, indicating, as they proceed, 

 slides having reference to the matter treated. This is the kind of lecture 

 that many teachers would gladly use to teach their pupils. 



The subjects could vary infinitely, the principal divisions being the 

 following: the useful plants and the noxious plants of the Province; the 

 animals useful to plants and those harmful directly or indirectly; the insects 

 and the fungi fighting for or against plants; the weapons of defence supplied 

 bv modern science.
