in Carolina that they would extinguish the flame of a 
candle when he went into a granary with one at night. 
And Dr. Harris says: ‘‘The grain-moth has spread from 
North Carolina and Virginia, where its depredations were 
first observed, into Kentucky and the southern parts be- 
tween the thirty-sixth and fortieth degrees of north lati- 
tude. But these are not the extreme limits of its occasional 
depredations, as it has been found even in New England, 
where, however, its propagation seems to have been limited 
by the length and severity of the winters.” 
Some of our distinguished agriculturists have written 
very valuable papers upon this destructive insect, to which 
those who choose can refer; e. g., Edwin Ruffin, Esq., of 
Hanover county, Virginia, published in the Yarmer’s Regis- 
ter, for November, 1833. Mr. Samuel Judah, of Vincennes, 
Indiana, in the Indiana Farmer and Gardener, for October, 
1845. Mr. Richard Owen, of New Harmony, Indiana, in 
the Cultivator, for July and November, 1846. E. Ruffin, 
Esq., in the Ainerican Agriculturist, for February and March, 
1847. 
It would be altogether too tedious to our readers to enter 
into the minute and various methods of destroying these in- 
sects and preventing their ravages, proposed and practiced 
by the above-named gentlemen, and so we only refer to 
their papers for the sake of those who are curious on the 
subject. We can only remark in this place that one process 
has proved effectual in destroying the insect without injur- 
ing the grain, according to our own personal observations 
in those rich grain countries of Hungary, Austrian Gallicia, 
Poland, and Russia, from the Neva, down through the 
Ukraine as far as the mouth of the Don and Volga, on the 
Black and Caspian seas. In every village of those coun- 
tries there are large kilns, or ovens, where the grain is put 
as soon as it is thrashed out, and during one day or one 
night is exposed to a temperature of one hundred and sixty
