It has been seen why confidence cannot be put in a seed; in otherwords, why it cannot be told what a seed will produce; therefore, thehorticulturist avoids the use of seeds as far as possible; the floristmust in many instances use them, where the plants used are annualsand where cuttings cannot be taken. For garden vegetables seeds mustbe used; that is why garden varieties run out in a few years and t^ r^ CO :^^ ? O Ln Oi c^ ?~o ^ rt f> <^ f C ;J ? - i f„ o. 52 LAND TEACHING. Others have to be bred up to take their places. It would hardly be toobroad an assertion to state that any variety of vegetables that hasbeen in use ten years is very different from the original first insure propagating the correct variety, where possible, the horti-culturist does so by the use of division or the use of a portion of theorginal plant. The following are some of the methods used: grafting,budding, layering, cutting, stolons, corms, etc. Grafting—Tbis is mainly used with trees, and in the propagation offruits. It is the cutting of a scion or short twig, from the tree onewishes to grow, and inserting it in a stock, usually of the same union takes place and the stock furnishes food for the scion, which,grows and bears fruit after its kind. Unions may be expected whenplants of the same variety are grafted one upon the other; family unite,beyond
