On Forcing Cherries. — The dimensions of the pots cherry trees grow in 
must be regulated according to the size of the plants, say from two quarts to 
two gallons. The soil in which they are potted must not be rich, as highly 
manured soil is apt to make the shoots too luxuriant, and cause them to gum. 
Put the trees into the houses at the close of the year, and give them veiy little 
water; when beginning to force, water sparingly, and admit as much air as the 
weather will allow night and day, for nothing is so much calculated to render the 
cherry impatient of forcing, as alternate ventilation in the day, and confinement 
at night. In frosty weather increase the fire, until with constant air the temper- 
ature does not fall below 32 deg. of Fahr. in this manner proceed slowly until 
the blossoms are all set, then raise the temperature at first to 65 deg. and after- 
wards gradually to 70, increasing the moisture of the atmosphere at the same 
time, and always taking care to keep the ventilation as abundant as possible. —

On the cuLTiRE OF ViNES ON THE OpEN Wall. — W. T. Salvin, Esq. of 
Croxdale, has a wall above eighteen feet high, used for the culture of vines. The 
fire places are made in the form of ovens, nothing but wood is burnt in them, 
as it is found vnXh the following regulation to produce a more steady heat than 
coal. After an accumulation of ashes is produced, they should be used to cover 
the embers at night, or at any time when those who attend the fires retire to 
rest, and also to regulate the fire during the day when less heat is required. 
The red-hot charcoal so covered will continue to give out heat for several hours, 
and is ready to rekindle a fresh supply of wood, whereas coal requires more con- 
stant attendance or it wdll soon go out The fires are commenced when the 
buds begin to break in -A.pril, and are continued night and day until the fruit is 
perfected, except a few weeks in July and August, if the season is hot. Rotten 
dung is put to the vine roots, and dug in during spring. The branches are 
trained to the wall, and pruned in the usual way. It is necessary to plaster the 
inside of the flvie in the best manner when wood is used, as otherwise the 
steam or smoke from the wood will force itself through the joints of the wall in 
the form of tar, and injure the grapes. — Id. 
Cl'LTURE OF THE HORSE RaDISH IN DENMARK AND GERMANY. The horse 
radish delights in a good rich and moist loam, and rather a shaded situation. 
The ground must be trenched and manured the year before planting. In the 
autumn, when the old roots are taken out of the ground, select all the small 
side roots from nine to twelve inches in length, and as thick as a quill or there- 
abouts; tie them in bunches, and preserve them in sand in a place protected
