“ It is pleasant to turn aside for a while from the busy human world, with its ceaseless anxieties, sorrows, and labors, to avert our gaze from the splendors of forest and garden, from the visible display of green foliage and rainbow-colored blossoms around us, and contemplate the silent and wonderful economy of that other world of minute or invisible vegetation with which we are so mysteriously related, though we know it not. There is something exceedingly interesting in tracing Nature to her ultimate and simplest forms. ”
