Harvest Moon. 
The present year is the third of a series of ten years in which 
the moon will prove the most beneficial to farmers for reaping 
and gathering in the produce of their fields; viz. from 1816 to 
1825 inclusive. The nine years preceding, namely, from 1507 to 
1815 inclusive, were of the class of those in which, from general 
physical causes, the harvest moon was least beneficial.
