and allowed to ferment 12 or 24 hours, according to the temperature, a 

 thick coaguluin separates from the dark clear portion, which possesses a

 cellar for a year or more.

 preceding, — but is nevertheless sweet and agreeable. The plant, however, 

 is generally treated as a weed, on all neat farms.

Ohs. Our Dewberry is a fine fruit, the earliest and the sweetest Black-
