On the Cultivation of Celery. 
from to 70 degrees of heat. In warm a situation, the soil at 
its surface is very liable to dry, and when the seeds have vegetated in 
part, drought destroys them; to prevent which it is necessary once or 
twice, or more, each day, to sprinkle the surface with water of the 
temperature of the house, until the plants are up. 
When the plants are about an inch high, the box is, removed to a 
peach or green-house; and when two inches high, they are pricked 
out into a frame, placed upon a slight hot-bed, which had been made 
a week or ten days previous. The day before the plants are to be 
pricked out upon the bed, the surface is made even, and some hard 
turf about an inch thick is laid over the bed, the grass-side under¬ 
most, and beaten as firm as possible^ This prepared sub-stratum 
prevents the roots from entering much into it, and thereby causes 
the plants to make tufts of fibres, which are veiy essential to the 
future progress of the plants. The tap-root is also checked, and 
generally prevents the plants from running whilst in that situation. 
Upon this prepared sub-stratum, two inches deep of well-rotted dung 
is sju'ead, and the surface smoothened; then about an inch deep of 
finely-sifted rich soil is laid on, and the plants are pricked out at about 
lour inches apart. All possible air is admitted to prevent their being 
ilrawn. 
I have observed that when the prepared compost of dung and soil, 
which is laid upon the turf, is much deeper than above stated, a great 
proportion of the plants run, but they rarely do so, when the manure 
is good and as deep as stated, provided plenty of air and water be 
given. 
When the plants are six or eight inches high, a piece of ground is 
prepared upon a border in a sunny situation; the soil is thrown out 
four inches deep, and turf is laid over the interior of the excavation, 
and prepared in other respects as directed for the hot-bed. When 
the dung is properly levelled, the plants are taken up, dividing the soil 
and manure with a knife, so as to have a square ball with each plant: 
they are then placed upon the dung at about eight inches apart. The 
spaces between the balls are filled up with rich soil. The plants are 
then well neutered, to settle the soil about the roots. 
When they are from tn^elve to eighteen inches high, they are re¬ 
moved with entire balls into the trenches, prepared in the following 
manner: the trenches are marked out five ft'et apart, centre from cen¬ 
tre, and the soil is thrown out eight inches deep and twenty wide. 
The trenches are then filled up with the following compost: two parts of 
good rotten dung, and one part of stiff bog soil, with bone dust sprinkled 
amongst it in a small proportion. The plants are then carefully 
removed, with balls entire, and placed in rows at eight inches apart,
