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.
