Henry David Thoreau Quote
I see in many places little barberry bushes just come up densely in the cow-dung, like young apple trees, the berries having been eaten by the cows. Here they find manure and an open space for the first year at least, when they are not choked by grass or weeds. In this way, evidently, many of these clumps of barberries are commenced.
