syringe with this mixture at the time I put on the sashes, and again 
when I begin to force. Should either mildew, scale, or green fly, 
make its appearance, I syringe repeatedly, often three times a day, 
chusing the hottest part of the day, in order to produce a vapour in 
the house ; and this I continue until the fruit is nearly full grown : 
it must be discontinued, however, as soon as the fruit begins to 
change, lest it might impart a disagreeable appearance to them. 
Culture of Commelina coelestis. —Sow the seed on a mo¬ 
derate hotbed with the other annuals,fabout the middle of February, 
or earlier ; but in the latter case it will be necessary to pot the plants, 
and keep them under glass until the beginning of May, when they 
may be turned out into the flower ground; or it may be sown in the 
open ground in the beginning of March. The ground should be 
moderately rich and light, although any ordinary garden mould will 
answer; cover the seed half an inch deep with light sandy-earth ; 
and should the weather prove genial, the plants, will appear in about 
a fortnight, and require no farther care then to be kept free from 
weeds, and watered in very dry weather. By the beginning of July 
the plants will be in blossom ; and either in beds, masses, or as soli¬ 
tary plants, add greatly to the beauty of the flower border. Persons 
possessing the plant may have it in blossom in May, or even earlier, 
by treating the roots as we do those of the Dahlia, viz.:—planting 
them in pots and plunging the pots in a moderate hotbed, placing 
them in decayed leaf-mould under glass—here they will soon vege¬ 
tate, and may be placed in the open ground as soon as danger from 
frost is not any longer to be apprehended. By treatment which 
every gardener understands, such as sowing at different seasons, the 
plant may be made to flower at any time, or be kept in blossom all 
the year round. The roots require, in order to preserve them from 
frost, only the ordinary care ol placing a few inches of sand, turf- 
mould, ashes, or the like, over them as they stand in the bed, or they 
may be raised and preserved in sand in the manner that carrots are 
sometimes kept during winter. 
Culture of the Mushroom. —Towards the middle of October, 
I empty the melon pits of the old dung, tan, or tree leaves, reserving 
any that appears fresh, which I mix with fresh stable dung, and re¬ 
turn to the pits, first placing a layer of entirely fresh dung at the 
bottom. I tread firmly as I proceed. When the pit is quite filled, 
I put on the sashes, tilting them to permit the escape of the steam. 
In a fortnight or three weeks, the dung will have subsided, and the 
heat will be sufficiently abated. I then place a layer of a few inches 
thick of horse-droppings, from a stable where the horses are fed on
