cords that in former times clearings were made here, and more 
emphatically is this told by the roots or stumps buried in the soil. 
Some portions in this part have been accurately surveyed 
by the Bureau of the Imperial Preserves for the first process of the 
afforestation now being carried out here. Through the kindness of 
Dr. Y. Siiiozawa, expert of the Bureau, I was able to secure all 
the data with which I express numerically the degrees of the 
alternation of the forest-regions. The surveyed portions were 
divided into a number of parts, and the deciduous trees and 
conifers contained in some parts marked with asterisks were 
actually counted. The supply of timber contained in those 
parts is finally mentioned. This supply will approximately show 
the density of the forests. 
The following tables show the l’elative frequency of both 
deciduous and coniferous trees in each part. The positions and 
the altitudes of the parts are given in the accompanying plate.
