The True Service (_Pyrus sorbus_) closely resembles the Mountain Ash in habit and foliage, but it is not a native of Britain, though it used to be claimed as such, on account of its growing in the more mountainous parts of Cornwall and in Wyre Forest, Worcestershire. The latter, however, is the only Service tree that could put in such a claim, for it grows--or grew?--far from habitations or cultivated land, and the presumption is that it has not owed its introduction to man. Still, "one swallow does not make a summer," and a solitary wild tree does not give the species a title to be reckoned as British. It is occasionally cultivated here, and its portrait, with a brief account of its points of difference from the Mountain Ash, may be useful. A comparison of the photographs from the boles of the two species will show a great difference: that of the Mountain Ash being smooth, whilst that of the Service is rugged. The leaf is similarly broken up into paired leaflets, but these are broader, and are downy on both upper and lower sides. The white flowers are as large as May-blossoms, and the fruits, which may be either apple-shaped or pear-shaped, are greenish-brown, with rusty specks, and four times the size of Rowan-berries. In winter, when there are neither leaves, flowers, nor fruits to help in the distinction, the bark may be taken in conjunction with the leaf-buds, which are green and smooth in this species, whilst those of the Mountain Ash are black and downy. The fruit may be eaten after it has begun to decay, as in the case of the Medlar. Loudon describes the wood of the Service as the hardest and heaviest of all the trees indigenous to Europe: fine-grained, red-tinted, susceptible of a high polish, and much in request in France for all purposes where strength and durability are needed. He further says that it takes two centuries to attain its full stature (fifty to sixty feet), "and lives to so great an age that some specimens of it are believed to be upwards of 1000 years old." We have already made reference to the meaning of the name Service. Another name--Sorb (from Latin _sorbeo_)--shows closer affinity for the fermented liquor indicated by Servise, for it means "drink down." A third name is Chequer-tree, which Dr. Prior tells us is an antique pronunciation of the word _choker_, in allusion to the unpalatable fruit, fit to choke one. Choke-pear, it will be remembered, is a synonym of the Wild Pear. Britten and Holland regard the name Chequer-tree as having no connection with choking, but an indication of the chequered or spotted appearance of the fruit.
