In Europe - at least that part of it which influences our literature - forest trees grow slowly and endure long. The " preservation " of old forests, and especial protection to young ones, becomes a question of grave national importance. Most of the newspaper talk, if on forestry in our country, is derived from library studies, and not from practical acquaintance with American trees. Noting the opinions of the Gardener's Monthly on this subject, the Lancaster Farmer well remarks:

" As a general thing, people greatly exaggerate the length of time required for a forest to grow up, and it is this as much as anything else, that causes the reluctance that exists in regard to planting. Let any man who located in Lancaster thirty years ago, take a stroll along those places which had not a tree or shrub on them then, and he will be astonished to now find large buildings perfectly embowered in trees. Thirty years more, and many of these trees will become large, unwieldy and perhaps dangerous, and will have to be removed, and younger and smaller ones planted instead. If sixty years develops so much, what may be expected from one hundred and sixty or two hundred in an open country ?"
