Vines for vineyards, with the exception of varieties of Rotundifolia, are propagated from cuttings of hard wood taken from the season's canes when the vines are pruned. The inactive buds in these cuttings may be brought into active growth, and roots induced to grow from the cut surfaces by various means. By this miracle of Nature, an infinite number of plants, in an endless procession, may be propagated from the product of a single seed, each plant complete in its heredity and differing from its fellows only in accordance with environment.
