NUMBER OF SEEDS PER POUND. 



In Table 4 is given by species the approximate number of seeds per 

 pound.

 PERCENTAGE OF GERMINATION. 



In Tables 5 and 6 is given the average percentage of germination 

 for seeds of different species, and the real value of the seed based 

 upon relative percentages of germination and of clean seed.

 TABLE 6. Practical germination per cent and real value of seed. 



1 These figures represent the number of days when germination was practically complete 

 and the percentage of germination within that time, rather than the absolute final germi- 

 nation record.

8 Western yellow pine seed germinates more slowly on proceeding from the Rocky Moun- 

 tains to the Pacific coast. Averages from both regions show that Rocky Mountain seed 

 germinates in about one-third of the time required for seed from the Pacific coast.
