4. The size of the cherries is the same on trees grown on the two stocks. The claim is made that apples and pears are a little larger on dwarf trees and that when peaches and plums are dwarfed the fruit is smaller. No one seems to have seen or to have thought that there are differences in the size of cherries grown on Mazzard or Mahaleb stock. [Illustration: _PRUNUS AVIUM_ (MAZZARD)] 5. Better unions are made with Mazzard than with the Mahaleb. This would be expected because of the close relationship of the Mazzard to orchard cherries. 6. The Mahaleb is probably the more cosmopolitan stock--will thrive on a greater diversity of soils than the Mazzard stock. In particular it is somewhat better adapted to sandy, light, stony, and arid soils that are not well adapted to growing cherries. Its root system is much nearer the surface of the ground and it is, therefore, better adapted to shallow soils than the Mazzard. 7. Though the evidence is somewhat conflicting on this point it is probable that cherries on Mazzard live longer than on Mahaleb. It may be that the frequent statements to this effect arise from the knowledge that dwarf fruit-trees are generally shorter lived than standard trees since there seem to be no records of actual comparisons. 8. Lastly, in climates where the cherry can be grown with reasonable certainty and in soils to which this fruit is adapted, varieties on Mazzard are more productive and profitable than on the Mahaleb stock. This seems to be the concensus of opinion among growers in the great cherry regions of California, Oregon, Washington, Michigan and New York. Several other stocks have been more or less successfully used for cherries and a great number have never been tried that might make good stocks. In a country as diversified as ours and in a state as variable in soil and climate as New York and with the manifold varieties of Sweet and Sour Cherries, it is almost certain that under some conditions there are stocks more desirable than either Mazzard or Mahaleb. The resources of the cherry-grower in this direction are so great that in this account we can but briefly outline them, describing but a few of the many stocks that might be used.
