The horticulturist of this progressive age must not rest satisfied with what he learns on his own ground. There is a vast outside world, full of busy, intelligent minds, not content with things as they find them, but searching, investigating, experimenting, and so successfully, that the horticultural art is largely indebted to them for the amazing progress it has of late years made toward perfection. These great unfolders of some of Nature's profoundest secrets do not hide their lights under a bushel. There is a perpetual interchange among them, by pen, by tongue, and through the press, of the experiences and discoveries of each, the common repositories of all which are the agricultural journals. There collected as in a reservoir, they become fountains of instruction, not only to the pioneer in horticulture, but even to the veteran, and those who refuse to drink thereat will ever continue in the rear of a great army whose march is unceasingly onward. No petty jealousy comes in to mar the harmony of the true votaries of horticulture. There is emulation, but not contention. The heart of such a man enlarges as he pursues his labors, his tastes become refined, his sympathies embrace all others having kindred aspirations; and the successes he may have achieved, with the processes by which they are to be secured, become the common property of all who are wise enough to appreciate them. Our neighbors were born with no such tastes or impulses as these. That it was so proved almost as unfortunate for us as it was for themselves.
