not make the desired accurate comparison of their growth with regard 

 to species and locality of mother trees. 



(2) As shown in the above table, second year seedlings from 

 young mother trees showed a better growth than those from old trees. 

 With regard to locality, seeds obtained from warmer sections gave better 

 growth than those from colder sections. Thus, Akamatsu seeds from 

 Kochi took the lead, followed by those from Tokyo, Mito and Miyagi 

 while seeds from Nagano, in the highest altitude, was most inferior. In 

 the case of Kuromatsu, too seeds from Kochi showed the best result, 

 followed by those from Mito while those from Akita, in the north, 

 came last. Sugi seedlings likewise from seeds collected in Owashi grew 

 best. Those from the seeds collected in Kyoto and Kumamoto came next 

 and followed by those from seeds produced in Tokyo and Mito. Those 

 obtained from seeds produced in Akita showed the poorest growth. 

 Taking the temperature of Tokyo as the standard, the farther south the 

 seeds come from is better the growth while the farther north they come 

 from is the worse the growth. 



(3) When seedlings put out the earliest spring buds? In the case 

 of Akamatsu, seedlings from Nagano put out buds first every spring, 

 followed by those from Miyagi, Tokyo and Mito in order of time, with 

 those from Kochi coming last. As for Kuromatsu, seedlings from Akita 

 were foremost, followed by those from Mito and Kochi in order but the 

 seedlings from Kochi gave better in autumn than the others. 



IV. The Growth of Seedlings in General 



In the spring of the third year after sowing in April, 1905, well grown 

 seedlings distinguished according to species, locality, age of mother tree, 

 etc., were chosen to be used as typical specimens and were transplanted in the 

 Station's ground. During eight successive years that have passed since then, 

 these plants were properly cared for and the mode of inflorescence, fructifi- 

 cation, etc., registered. The results may be summarised as follows: —
