The plum is not so particular as the pear about soil, yet it has its preferences. It is not so deep-rooting as the apple and pear are; the character therefore of the lower soil is not so important. But stone-fruits require lime. In planting for profit, no site should be selected for a large plantation if the soil is deficient in lime. It is true that lime can be added, but this plan may suit a private garden, not a large plantation for profit. The plum being hardier than the pear will flourish in most soils, even in a heavy loam, but not in light sandy or gravelly soil. In the latter case, something may be done by heavy manuring and frequent removal. The trees in the R.H.S.'s garden at Chiswick are a triumph of skilful culture, as good crops are raised on many trees in a hot and gravelly soil. Some damsons, however, do not thrive there. But such culture is costly. In soils of an intermediate character, much may be done by adding other materials as suggested for pears. If there is any doubt about the amount of lime in the soil, an analysis should be obtained, and special notice taken of the trees in the neighbourhood. The plum (like the pear) will not thrive in a low, wet, undrained locality, nor in one that is very dry or exposed. Drainage is essential to success. If, in a rainy season, water in a clay soil is allowed to remain round the roots, canker or gumming is pretty sure to follow. Excessive moisture is as bad as extreme dryness. The slope of the ground, therefore, is a matter of importance. In Essex there is often land quite level with a heavy clay soil difficult to drain; such soil would not suit plums, though it might suit quinces. The aspect as well as the slope must also be considered. For the better class of plums, _i.e._ dessert varieties, where sweetness is expected, a position open to the southern sun is best, but they will also thrive if the aspect is S.-E. or even S.-W. Culinary and hardy varieties might be planted in the colder aspects to the N., N.-E. or N.-W. Proper shelter must by no means be forgotten. Bitter north winds may injure the bloom almost as much as frost or rain; strong winds from the E. or S.-W. may do great damage to heavy crops. Mr Lewis Castle in "Plums for Profit" (edited by myself, S.P.C.K.) suggests that "Canadian and Italian poplars make a good break if tall growers are required, but cherry plums, the myrobalan, will grow into a strong hedge in two or three years' time if the height be sufficient." Damson hedges serve a double purpose and afford good protection. He also suggests that some of the ornamental crabs are similarly useful for protection. Of these the Transcendant and Hyslop or Dartmouth produce good crops of lovely fruit which are excellent for cooking purposes and would probably sell well. PROPAGATION AND STOCKS
