The first column of figures gives trie weight in grams of the 

 various lots of seed. It will be observed that of the first variety, 

 Harvest Home, the large seed weighed somewhat less than double 

 that of the small seed while of the two other varieties, the large 

 seed weighed more than twice as much as the small. The heaviest 

 heads were produced by plants coming from the large seed while one 

 of the smallest head was also produced by the large seed. In the 

 case of the two last varieties referred to in the table, the smallest 

 heads in comparison were from small seed. The figures relating to 

 the maturity of the heads are so contradictory that no conclusions 

 can be drawn regarding that point. The facts presented in the last 

 column are perhaps the most striking and at the same time of the 

 most value. These figures represent the ratio of the average weights 

 of the heads compared. Representing the average weights of the 

 heads from the small seed by 1, we find in case of the first variety 

 that the average weight of the heads from the large seed is repre- 

 sented by .94. In other words, the large seed produced heads which 

 averaged six per cent, less by weight than did those from the small 

 seed. The average weights of the two other varieties,Eeynolds Early 

 and Ballhead, were 37 per cent, and 69 per cent, respectively in favor 

 of the heads from large seed. 



Deduction. It seems probable that the size of the seed has some in- 

 fluence upon the size of the head, the larger seeds as a rule, producing 

 the larger heads. 



2. Results of tying up the outer leaves. The idea has been 

 entertained, that by binding the outer leaves together over the head
