table seeds, namely that the use of large seeds results in a better 
all round later development and a greater final crop. 
3. The Rocky Mountain varieties of Pinus ponderosa produce 
smaller seeds, their germination begins earlier, their germination 
period is shorter, and their germination curves rise much more 
rapidly than in the case of the Pacific coast varieties of this 
species. 
4. Except for the size of the seed, the same relations hold for 
the Rocky Mountain and Pacific coast varieties of Pseudotsuga 
taxifolia. Blumer noted the slow germination of Pinus pon- 
derosa and Pseudotsuga taxifolia from the coast and he also 
noted the great difference in size of the seed of Pinus ponderosa. 
These observations are corroborated.
