Meteorological Journal at Marietta, Ohio, for 1846. 213 
The year which has just closed, has been one of unusual fer- 
tility, having been remarkable for that regular distribution of heat 
and moisture, that would naturally produce a favorable result. 
Crops of all kinds have been good and abundant, especially that 
of fruit. Apples ripened much earlier than usual, owing to the 
warmth and moisture of the summer months, so that many of 
our winter varieties were changed into those of autumn, being 
mature a month earlier than usual, and causing a rapid decay of 
the fruit intended for winter use. Several of the winter kinds, 
especially greenings, ripened and fell to the ground in August, be- 
ing a total loss except where they were cut and dried. Peaches 
also, suffered from the excessive rains of August, much of the 
fruit cracking open and decaying upon the trees. Grapes were 
greatly injured from the same cause. The warmth and moisture 
of June and July, caused a mildew to appear on the leaves and 
fruit, which could not be checked by the usual remedies, and the 
grapes perished in great quantities. On some vines a small in- 
sect destroyed the vitality of the leaves, and the crop could not 
ripen from a Jack of the usual juices elaborated by them. The 
“ potato rot,” so ruinous to this vegetable in some parts of the 
world, did but little damage in this portion of Ohio—much less 
than in 1845; and it is to be hoped it may disappear altogether. 
No effectual remedy has been found ; and as it came without any 
known cause, it may perhaps cease in the same manner. 
_ The amount of rain and melted snow, is 46°27 inches; which 
is more than in 1845, by twelve or thirteen inches. ‘The three 
summer months furnished nearly twenty inches, and the month 
of December six and a half inches, chiefly of rain. The Ohio 
river has been navigable for boats of a large size all the season. 
The mean temperature for the winter months, is about seven de- 
grees colder than the winter preceding ; severe weather commen- 
ced early, and the navigation of the Ohio was much obstructed 
With ice nearly all the winter. An abundance of this valuable 
article was formed to lay up for summer use, while the winter 
previous there was none frozen of sufficient thickness. | 
The mean temperature of the spring months, was 53°22°, 
which is a little below that of 1845, but was much more uniform 
and regular in temperature. 'That of March was nearly the same,
