If this department has been regularly attended to, the plants will be in a fresh healthy state. Where there is any sickly appearance, heat has been deficient, or insects of a destructive character are preying upon them. Too much water at the root frequently causes the foliage to become yellow. It will add greatly to their general improvement, to syringe the whole twice or three times a week, observing to do it in the morning about sunrise; and it is highly necessary that the water that is used should be of the same temperature as the house; and at all times, whatever water is given to the roots, the same must be observed. For airing, see last month, observing, as the season advances, to increase the quantity.

Continue to fumigate when any of the Green-fly appears, (see January for directions,) and where there are any of the plants infected with the white scaly insect, clean them as there directed. If overlooked for a few months, they will be increased tenfold. Very frequently, where there are only a few, they are neglected until the plant is overrun with them, and then it may be said, it is impossible to dislodge them entirely. Clear off all decayed leaves from the plants. These will have made fresh shoots, and the decayed leaves very much disfigure the whole collection. We would not have repeated this observation, if it was not an essential point, and one which is so frequently neglected.

OF SHIFTING PLANTS.

Those AlstroemÈrias that are growing freely, and in small pots, should be put into pots of a larger size. This genus of plants will not flower except they are encouraged with frequent shifting: they are all beautiful.
