There would be nothing to worry trees in these mixed forests — little

Travelling Lecture Sets in the West 



Ready-prepared Illustrated Addresses Now Available to 

 Manitoba, Saskatchewan, Alberta and B. C. Speakers 



In response to many requests from Western members, the Canadian 

 Forestry Association is establishing at Winnipeg, Prince Albert, Calgary 

 Kamloops, and Victoria, five Travelling Lecture Sets for the use of public 

 speakers, school teachers and others desiring to hold meetings for adults 

 or children. So successful have these Travelling Lecture Sets proved in 

 Eastern Canada that benefits quite as notable are bound to ensue from their 

 wider employment in the Prairie Provinces and British Columbia. 



Each Set consists of from fifty to sixty lantern slides, mostly in colors, 

 and a complete manuscript, bound in boards, all in a break-proof box. The 

 slides are numbered and correspond to descriptive paragraphs furnished with 

 the lecture manuscript. Scores of school principals, clergymen, etc., have 

 found these Lectures most entertaining and instructive. They have been 

 made quite non-technical, although clearly bringing before the audience the 

 essential points of forest protection and the science of forestry. 



By courtesy of the Dominion Forestry Branch and the Provincial For- 

 ester of British Columbia the Sets will be established in the government offices 

 so that application may be made direct to the District Inspector of Forest 

 Reserves at Winnipeg, Prince Albert, Calgary and Kamloops, and to the 

 Provincial Forester, Victoria, B.C. for the use of one of these Sets. There is 

 no charge whatever in connection with these Travelling Lectures, except 

 for the small expressage fee necessary to take the Set to and from engage- 

 ments. Those of our Western members possessing a stereoptican and desir- 

 ing the use of these Sets between receipt of this Forestry Journal and Jan- 

 uary 1, 1919, should write direct to the Secretary, Canadian Forestry Associa- 

 tion, Booth Building, Ottawa, and after that date to the addresses given above.
