THE HOT-HOUSE. 
Fire-heat should now be totally discontinued, except in 
the more northern parts of the eastern states, where a moderate 
fire at night, during the first week of the month, may in some sea- 
sons be necessary; but still continue for the Pine-Apples, a con- 
stant moderate heat in the bark-bed, agreeably to the intimations 
given last month. 
Pine Apples. 
The Pine Apple plants will now require frequent and moderate 
refreshments of water, which, during the summer season, should 
be given late in the afternoon; let this not be given in too great 
quantities at any one time, for such, would not only damp the heat 
of the bark, but also loosen the plants in the pots. 
As the weather increases in heat, give air in proportion, both by 
the front and roof-lights; but especially when the thermometer 
rises above seventy degrees of Fahrenheit; for that is necessary, 
in order to have large and good fruit. When the weather gets very 
hot, the front lights must be kept open night and day, but the 
roof-lights should be closed every night, particularly in cloudy 
weather, to preserve the tan-pit from sudden rains, and ought to be 
opened again early in the morning, especially in warm weather. 
General Care of all Exotics in the Hot-House. 
Continue also, to give plenty of air to the plants in all the hot- 
house departments, supply them duly with proper waterings; and, 
if any want shifting into larger pots, let it be done now as soon as 
possible, keeping the whole clear from decayed leaves, &c. If casual 
irregularities occur in the shoots or branches, prune or regulate 
them, as may be required, and cut away any decayed parts; observ- 
ing the same general directions as in the two preceding months. 
Propagating the Plants. 
You may still continue to propagate, such plants as you desire, 
by cuttings, layers, suckers and seeds, in the manner directed in 
March and Afiril. 
Any time in this month you may plant cuttings or slips of Cac- 
tuses, Euphorbiums, Aloes, Agaves, Sedums, Mesembryanthe- 
mums, Stapelias, and other succulent plants, laying them in a dry- 
shady place a week or ten days, according as they are more or less 
succulent, before they are planted, that the wounded parts may heal 
over; otherwise, they are subject to imbibe too much moisture and
