The essential points to be attended to in the Hot-house during this month, are fire, air, and water. The former must be applied according to the weather, observing not to allow the temperature to be under fifty degrees, and it ought not to continue long at that degree; fifty-two degrees being preferable. The shutters should be on every night when there is any appearance of frost, and taken off early in the morning. Admit air in small portions every day that the sun has any effect, and the atmosphere mild, observing that the temperature of the house be above sixty degrees previous to admission. Shut all close early in the afternoon or when any sudden changes occur.

OF A CISTERN AND WATER.

In watering it is important to have the water of the same temperature in this department as the roots of the plants. To have this there are two kinds of cisterns, or tanks, that might be adopted; one may be sunk in the house under ground, either closely plastered, or lined with lead, and neatly covered up, having a small perpendicular pump therein, or placed so that the water could be lifted by hand. The other might, where convenience will admit, be placed over the furnace, either in the back shed, or inside of the house, and the water could be drawn off this by a stop-cock. These can be supplied in part with rain water by having spouts round the house to lead into the cisterns, supplying any deficiency from the pump. Thus water of a congenial temperature may always be at hand, which is of great importance to the healthful constitution of the plants. The water must now be given in moderate portions, examining the plants every day. Be careful in watering bulbs, as the smallest supply is sufficient for them at present. Succulents will require a little every two weeks, except they are over the flues, when they may have some every week.

Constantly clear off all decayed leaves, and carry them out of the house, which sweep and wash clean, and keep all in the neatest order.
