Scientific authorities account for it by the flow eastward of a warm current from the Japan coast.
A further proof of this current is given in the finding of a Japanese junk adrift on this coast with all hands dead, a few years ago. Persons are able to camp out in all seasons of the year with a few trifling exceptions. The air is salubrious on this coast, and blizzards, cyclones, drouths are unknown. There are few days in the year when labor of all kinds cannot be performed out doors. Three fourths of the days in the winter time are as warm as the average of summer days.
