might try the effect of excessive drying, for a month seems to be long
enough for the process.--(Gardener's Chronicle.)

A Mr. Penoyer, of Western Saratoga, Illinois, publishes the following,
which he recommends as a perfect cure and preventive of the potato
rot, having tested it thoroughly four years with perfect success;
while others in the same field, who did not use the preventive, lost
their entire crop by the rot. It not only prevents the rot, but
restores the potato to its primitive vigor, and the product is not
only sound, but double the size, consequently producing twice the
quantity on the same ground, and the vines grow much larger, and
retain their freshness and vitality until the frost kills them. Aside
from the cure of the rot, the farmers would be more than doubly
compensated for their trouble and expense in the increase and quality
of the crop. The remedy or preventive is as follows:--"Take one peck
of fine salt and mix it thoroughly with half a bushel of Nova Scotia
plaster or gypsum (the plaster is the best), and immediately after
hoeing the potatoes the second time, or just as the young potato
begins to set, sprinkle on the main vines, next to the ground, a
tablespoon full of the above mixture to each hill, and be sure to get
it on the main vines, as it is found that the rot proceeds from a
sting of an insect in the vine, and the mixture coming in contact with
the vine, kills the effect of it before it reaches the potato." I
cannot but consider Professor Bollman's as the most important of the
two remedies suggested.

The potato crop of the United States exceeds 100 million bushels,
nearly all of which are consumed in the country; the average exports
of the last eight years not having exceeded 160,000 bushels per annum.

According to the census returns of 1840, the quantity of potatoes of
all sorts raised in the Union, was 108,298,060 bushels; of 1850,
104,055,989 bushels, of which 38,259,196 bushels were sweet potatoes.

Last year (1852) there was under cultivation with potatoes in Canada,
the following extent of land:--

Acres. Bushels.
Upper Canada 77,672 Produce 498,747
Lower Canada 73,244 Produce 456,111

About 782,008 cwts. of potatoes are annually exported from the Canary
Islands. In Prussia, 153 million hectolitres of potatoes were raised
in 1849. In 1840 Van Diemen's Land produced 15,000 tons of potatoes,
on about 5,000
