The Honourable, 



The Minister of Agriculture, 

 Ottawa. 



Sir, — I have the honour to transmit herewith the manuscript of 

 Bulletin 39 of the Second Series, on Poisonous Plants. 



This bulletin has been prepared by Miss Faith Fyles, Assistant 

 Botanist, and is profusely illustrated from drawings made by the author. 

 These, with the many careful descriptions given of the various poisonous 

 plants, make the bulletin a valuable one to those engaged in botanical 

 studies. 



The main object in its publication, however, is to give the farmer and 

 stock-raiser a means of recognizing and identifying such poisonous plants 

 as may occur on his pastures and ranges. Symptoms of poisoning by these 

 plants are also described and methods of treatment indicated. 



It is hoped that the bulletin will do much to lessen the present heavy 

 annual loss among the various classes of live stock from the above cause. 



I have the honour to be, Sir, 



Your obedient servant, 



E. S. ARCHIBALD, 

 May 14, 1919. Director Dominion Experimental Farms.
