experiments have been successfully conducted on five hundred and 

 seventy-one Ontario farms. Those varieties which have given the 

 largest average yield of grain per acre, each producing upwards of 25 

 bushels, are the Egyptian Mummy, Chancellor, Prussian Blue, and 

 Striped Wisconsin Blue ; and those varieties which have given an 

 average yield of between 24 and 25 bushels per acre are the Early 

 Britain, the Canadian Beauty, and the Canada Cluster. 



Each experimenter has been asked to examine the peas carefully 

 for the weevil by .splitting open 200 peas from each plot and counting 

 the number of weevils in the form of either little white worms or 

 darkish brown beetles. 



From the reports received, we find that, with the exception of a 

 very few scattered places, there is no pea weevil north and east of a line 

 drawn from Brock ville to Midland. The accompanying map (page 9) 

 shows the distribution of the insect throughout Ontario, based largely 

 on the reports of our co-operative experimenters for the past two 

 years (1901 and 1902). Reports have been received from all of the 

 districts in New Ontario, and indicate something of the great possi- 

 bilities of that country in supplying peas of superior quality until the 

 pea weevil can be eradicated from south-western Ontario. 



Selection of Seed. 



Large and Small Seed. An experiment has been conducted 

 for five years in succession to ascertain the relative value for seed 

 purposes of large and small peas of the same variety. In each of five 

 years, a certain number of large sound peas were carefully selected 

 and counted. A similar number of small sound peas were selected at 

 the same time and from the same variety. The small peas were 

 usually about one-half the size of the large ones In each year, both 

 lots were sown at the same time and on uniform plots of equal size, 

 situated side by side. 



The average results for the five years were as follows : Yield of 

 the large seed, 80.3 bushels of grain and 1.3 tons of straw per acre, 

 and that of the small seed, 28.9 bushels of grain and 1.1 tons of straw 

 per acre. A certain number of large peas, therefore, gave 26.8 per 

 cent, mure grain, and 18.2 per cent, more straw than a similar 

 number of small peas of the same variety in the average of five 

 years' experiments. 



Whole and Split Seed. Many farmers thresh their peas with 

 a grain separator and part of the peas are split in the process of 

 threshing. Some farmers carefully separate the split peas and sow 

 nothing but whole seed ; while others sow their peas without making 

 this separation. An experiment has been conducted at the college for 

 eight years in succession by sowing on uniform plots equal quantities 

 of whole and split seed of the same variety. The average results for
