Tab. III. Containing the average number of rainy days in each month, for the live 
years from 1901 to 1905 inclusive. 
The figures of this table, being the result of observations 
made at different altitudes, do not give us any fair idea of the 
number of rainy days at the 1000m. altitude. We see, however, 
that these observations throw some light upon the investigation 
of the present plant-formation. The number of rainy days for 
Shiraito and Shbji are the greatest ; hence they have the most 
abundant vegetation. Moreover, it may be urged that the 
Shiraito must have the most days of rain, for this station, not- 
withstanding its low elevation, has more rainy days than the 
Nakano station which lies almost at the altitude known to have 
the maximum precipitation. As will be shown afterwards, the 
most abundant growth of deciduous trees is found on the 
Shiraito side. 
2) Temperature. The following table will give us the 
readings of the thermometers at the five stations. Here, 
however, we must consider the temperature at the altitude of 
1000m., which temperature can be calculated from the known 
readings.
