will doubtless do more. In my official capaeity I shall do mv utmost 

 to bring- at)out what 1 believe is possible — the extermination of the pea 

 weevil in Canada — and I now make an earnest appeal to the members 

 of this association to cooperate with me in the same direction. If all 

 who sow peas in Canada and the United States will adopt any one of 

 the remedies and carry out the suggestions made beloAv, I am confident 

 that a tremendous advance will be made in a single 3 ear, and that as 

 earl}^ as the second year extermination might be looked for. 



REMEDIES. 



Fiim'i<jati(>n. — Fumigation Avith l)isulphid of carbon is a sure rem- 

 edy. When properly done, either in specially constructed l)uildings 

 known as "bug houses" or in any tight bin, every weevil is surely 

 killed if the seed containing them is fumigated for forty-eight hours 

 with this chemical, using 1 pound l»y weight to every 100 bushels of 

 seed, or, in smaller quantities, 1 ounce to every 100 pounds of seed. 

 For the treatment of small quantities of seed, particularly by farmers, 

 I have found that an ordinary coal-oil barrel is very convenient. 

 This will hold about 5 ])ushels, or 300 pounds, of seed, which may be 

 treated with 3 ounces of bisulphid of carl)on. Care must l)e taken 

 to close up the top tightly. This is l)est done with a cap made spe- 

 cially for the purpose, but fine sacks laid smoothly on the top, over 

 which boards are placed with a weight on them to hold the covering 

 down closely, will answer. Fumigation with bisuljDhid of carbon is, 

 I believe, the remedy most to be relied on in this campaign. It is 

 perfectly efl^ective, isiiow regularly used by the large seed merchants, 

 and in future will l)e much more generally used. 



IloUllng over med. — Where only a few peas are used, a most reliable 

 remedy is the holding over of seed until the second year. Peas should 

 alwa3\s ])e l^agged up and the sacks tied at once after threshing. 



Treating imth eodl oil. — A remedy Avhich has l)een used by many 

 farmers with satisfaction is to drench the seed with coal oil, using 

 about half a gallon to a barrel, or 5 ])ushels, of peas. While applying 

 the coal oil the seed should lie placed on a floor where it can be shov- 

 eled over constantly to insure the treatment of all the grain. 



Scalding seed. — When peas are found at the time of sowing to con- 

 tain living weevils, these may be destroyed by simply pouring them 

 into a pot of scalding water. The water should be drained ofl" at once 

 or the seed cooled l)y turning in cold water. 



RECOMMENDATIONS. 



1. Everyone, when purchasing seed peas, should refuse determinedly 

 to buy any without the assurance that they have been treated; and, 

 further, even after this, he should examine for himself and see that
