Considering the average of the 6 years we came to the following 

 conclusions. 



(1) The number of flowered saplings are almost the same for 

 different plots, regardless of position, surroundings and the nature of soil. 



(2) The number of the flowered saplings, as in the previous 

 experiment made with regard to locality, are influenced by the age of the 

 mother trees and is always greater for younger mother trees. 



(3) The saplings, although dependent upon the soil on which they 

 planted, showed always far better growth when they originated in young 

 mother trees. 



In general, better grown saplings give more flowers. In other 

 words, number of flowered saplings perfectly show likewise vigorous life. 



V. Conclusion 



The following conclusions may be drawn from the statements on the 

 previous pages: — 



(1) Seeds obtained from a young mother tree are large and seed- 

 lings grown from such seeds show a better growth. 



(2) Seedlings from the seeds produced in localities warmer than 

 that of the nursery, will give a better growth over than those obtained 

 from colder districts, so that it is always advisable to bring seeds from 

 warmer places. If there is fear on frost, care should be taken to protect 

 well against it, since the seeds from warmer localities continue their 

 vegetation later in the fall, so that new buds coming late may suffer from 

 an early frost and perish in winter. 



(3) Forest trees grown from seedlings originating in warmer dis- 

 tricts than the nursery bear many flowers and fruits already in their 

 early years; trees grown from the seeds of a climate colder than that of 

 the nursery bear few flowers and fruits and are very slow in growth. 



As to the influence of the age of the mother tree, old trees give rise 

 to a smaller number of flowering and fruits bearing saplings and those 

 of slower growth. This is particularly true in the case of Sugi ; but in 

 case of Akamatsu and Kuromatsu, the difference is hardly recognisable. 



For the reasons above stated, the best tree seeds should be taken 

 from a young mother tree grown in a locality resembling in climate of 

 the place where the seeds are to be sown. 



In the preceding pages the term " Young tree " is taken to signify 

 the tree from 20 to 30 years old.
