As what might be called the foundation of horticulture, the leading facts were given relative to the handling, care of, and planting of seeds in the first chapter. In this connection it is only necessary to state that seedling production is only practised in horticulture and forestry where exact reproduction is not required, such as garden seeds, flowers, nursery fruit stocks, forest- and shade-trees, and last but not least, in starting new varieties from crossed seeds or seeds from selected plants. But in this case each individual plant found worthy of attention must be propagated later by division of the root or top.
