As in the case of Apples, the list of Pears in the catalogue of a nurseryman is bewildering in the number of varieties offered. The market gardener growing Pears wants the earliest he can get, and should have a succession up to the beginning of November. If he has Pears that require keeping longer than that, he will find the constant looking over which will be necessary swallow up the profit in expenses, unless he happens to be in a situation with soil and climate so specially adapted that it pays him to make Pears his speciality. The ordinary market grower will find that a Pear which crops, though dismissed by experts like Mr. Bunyard as "second" or even "third class", will pay him much better than the " delicious ", "melting ", "first-class " varieties which only deign to produce a crop when all conditions are quite favourable.
This is an old-fashioned Pear, the mention of which will make the expert reader smile. It is, nevertheless, a useful variety for the market grower. Its growth is upright and compact, it is a good cropper, sells well for the barrow trade, and can be put on the market in the home counties at the end of July. It is only suitable for the Pear stock, and makes a good wind shelter for the rest of the plantation.
This old Pear is still unbeaten for an early market fruit. The tree is very vigorous in growth on the Pear stock and often a puzzle to prune. It takes five to seven years to come into bearing, but then it nearly always bears and the fruit sells freely. It is early-flowering, and its large white blossoms borne in trusses of six or eight make it quite the most beautiful of all Pear trees. It is apt to canker on cold soils; on such it should receive frequent dressings of lime and spraying, when dormant, with the copper sulphate spray recommended for Apple canker (p. 90).
This early variety seems always to meet with a ready sale in London; it is one of the oldest Pears in cultivation. Some trees in Middlesex are probably 200 years old. It is a heavy cropper, the fruit is small, the colour yellow, and the flesh "flocky ". It is ripe at the end of July. The tree wants age before coming into bearing.
This is a hardy Pear freely grown in the home counties. It is a free bearer and flourishes on a wider range of soil than most Pears, although to get its pretty spotted skin clear from rust it must be planted on deep light soil. Many thousands of bushels of this pear are sent from London by sea to the north of England and Scotland during the first weeks of September. It sold ripe in London in 1910 at 7s. per bushel. The tree easily takes an attractive shape, and after the first few years requires little pruning. Although classed as a common Pear, to use an old aphorism, it will buy the horse while some so-called better varieties are buying the harness.
A long brown pear with russet skin and tree of slender, weeping growth. When planted on light deep soil it is a profuse bearer. The fruit should be gathered just before Michaelmas, as its long slender stalk allows it to sway on the tree, and an autumn gale will give the grower the unpleasant surprise of finding his Calebasse gathered for him in the night, and injured also. It is not worth planting on unsuitable soil.
