If the occupier intends to manage this garden himself, he must be at home every day throughout the year; with the exception, perhaps, of a month or two during summer, when his forced trees, having yielded their crops, are in a dormant state; and when he may commit the care of his reserve department, and of his green-house, to a commercial gardener in the neighbourhood. If he employs a gardener, it must be one who thoroughly understands his profession, and who is so decidedly steady and regular in his habits, that the utmost confidence may be placed in him. The neglect, for one night, during severe frost, of the fire which heats the hot-water apparatus, or the making of too large a fire in a mild night, would be sufficient to destroy a whole crop of either peaches or grapes. For this reason, not only a remarkably steady man must be employed as gardener, hut one who lives either in the house, or near at hand; so that he may be able to attend the fires, when necessary, at any hour of the night.

Even during the day, there is great danger of overheating forcing-houses, either by sun heat alone, or by the joint effect of sun heat and fire heat; so that in the day time the occupier or his gardener will require to be as vigilant as during the night.
