Tt will be seen from this table that most of the seedlings from 
the small seeds fall between the limits 2.6-s.0 while most of the 
seedlings from the large seeds fall between the limits 3.1-5.5. 
Just as in the case of Pinus ponderosa above we see that the 
greater per cent. of small seedlings are found among the seedlings 
that germinated from small seeds. The average difference in 
size of 100 plants of each kind is 0.69 cm. in favor of the plants 
from large seeds. 
The measurements taken for another climatic variety of Pseu- 
dotsuga taxifolia were as follows: 
Pseudotsuga taxifolia (Colorado)—Age, 4 Days 
31 seedlings from small seeds averaged ................. 3.4 cm. 
76 seedlings from large seeds averaged ................. 3.9 cm. 
Here again there is a difference of 0.5 cm. in favor of the large 
seeds. In comparing Pseudotsuga taxifolia with Pinus ponderosa 
it is found that the size of the seed makes a greater difference in 
the case of the latter species than in the case of the former. Also,
