in the medium cones 47.0 per cent, and in the small cones 54.2 per 
cent. 
In each cone it was found that there were twice as many large 
as small seeds, and more medium seeds than there were large and 
small seeds together, except in the small cones where there was a 
slight decrease. 
The quantity of large seeds amounted to about 30 per cent of the 
total in the large and medium sized cones, and 43 per cent in the

small cones; medium seeds made more than 50 per cent of the 
total in the large and medium cones, and 35 per cent in the small 
cones; while the small seeds formed 12 to 17 per cent in the large 
and medium cones, and 21 per cent in the small cones. 
The weight of seeds ranged from 4.20 to 11.07 gm. per hundred 
seeds, the average being 8.28 for large cones, 7.56 for medium 
cones, and 6.85 for the smallest.
