temperature may be always at hand, which is of great im- 
portance to the healthful constitution of the plants. The 
water must now he given in moderate portions, examining 
the plants every day. Be careful in watering bulbs, as the 
smallest supply is sufficient for them at present. Succu- 
lents 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.

rature observed last month must be continued, but not ex- 
ceeded, which would cause premature vegetation, of which 
the result and effects have already been observed. Always 
kindle the fires in time, to prevent the heat from being 
lower than what has been mentioned, lest a severe frost 
should take place, as then a considerable lapse ensues 
before the fire has any effect ; and if the wind blows high, 
the result might be injurious, unless the house be very 
close. 
OF SHUTTERS. 
The benefit of these in severe weather is of material 
service, for the preservation of an even temperature in the 
house during the night, when changes are not observed; 
but they ought never to remain on through the day, when 
the fire can be properly attended to. If the front and the 
lowest sash of the roof are covered with these, it is gene- 
rally sufficient. They should be made of three-quarter 
inch boards, closely grooved together, having a cross-bar in 
the centre, and one at each end and each side, which will
