One of the greatest sources of enjoyment resulting from the possession of a garden is the endless variety which it affords, both in the process of vegetation as it goes forward to maturity, dormancy or decay, and in the almost innumerable kinds of plants which may be raised even in the smallest garden. Add to it a small greenhouse what a source of pleasure and instruction does it not hold out to the Amateur? Exactly in proportion as the out door work becomes less urgent, the in-door operations become more numerous. The amusements and the products which a small glass-house affords in the hands of an expert or an ingenious amateur, are almost without end.
