even be poured upon articles of food, and, after thorough exposure to 

 the air, not a trace of it will remain. 



There is as yet but little trouble from the pea weevil in the extreme 

 eastern and northern portions of the Province, where peas can still 

 be grown to good advantage. Although we have not made compara- 

 tive tests of different varieties of peas in our experimental grounds 

 during the past two years, a reference might here be made to the re- 

 sults of former experiments. Fully one hundred varieties of field peas 

 have been grown in our experimental plots within the past fifteen years. 

 For a very rich soil, the White Wonder gave the greatest yield of 

 rgain per acre; for a soil of medium quality, the Early Britain gave 

 a very high yield, and the New Canadian Beauty gave a moderately 

 high yield of seed of excellent quality ; and for poorer soils, the Prus- 

 sian Blue and the Tall White Marrowfat, which are both very long 

 strawed varieties, gave excellent results. 



Although we have mentioned previously that no comparative ex- 

 periments of different varieties of field peas have been conducted dur- 

 ing the past two years, the Early Britain variety was grown and ripened 

 in 1904, and was carefully examined in order to ascertain the ravages 

 of the pea weevil. As determinations regarding the percentage of 

 weevilly peas of this variety have been made since 1894, the percentage 

 of crop infested with the weevils each year gives us some information 

 regarding the ravages of this pest in this section of the Province. The 

 following gives the percentage of weevilly peas of the Early Britain 

 variety for each of the eight years : 1894, 2 ; 1895, 7; 1896, 11 ; 1897, 

 34; 1898, 49; 1900, 75; 1901, 96; and 1904, 61 per cent. It will there- 

 fore be seen that the damage caused by the pea weevil in 1904 was only 

 about two-thirds as great as it was three years ago. As the farmers 

 in the vicinity of Guelph have stopped growing peas to a considerable 

 extent within the past two years, the ravages of the pea weevil seem 

 to be somewhat reduced. 



Field Beans. 



Field beans are not grown very extensively throughout Ontario, 

 except in the southwestern part, and especially in the counties of Es- 

 sex and Kent. Fourteen varieties of beans were under experiment in 

 our trial grounds at the College in 1904. The yields were compara- 

 tively low this season, probably due to the cold, wet weather in this 

 part of the Province. The seven highest yielding varieties in the past 

 season were: New Prize Winner, 17.4 bushels; Schofield Pea, 16.6 

 bushels; White Wonder, 15.3 bushels; Small White Field, 15.3 bush- 

 els; Burlingame Medium, 14.8 bushels; the Pearce's Improved Tree. 

 14.8 bushels per acre. In the average results for eight years 

 of thirteen varieties of beans, which have been grown for that 

 length of time, we find that those varieties which gave the 

 greatest yields per acre were the White Wonder, 21.8 bushels; 

 Pearce's Improved Tree, 21.3 bushels; Burlingame Medium, 20.8
