6. They decay very readily, and must, of all apples, hang longest on the tree. 7. The really sweet and at the same time aromatic apples belong to the Reinettes, only as regards their shape, their character, and their fine and firm flesh. 8. Apples with fine, firm, crisp flesh, which cannot of themselves form a distinct class; for instance, the Pippins belong to this class. +ORDER I.--SELF-COLORED REINETTES.+ 1. Having a uniform green ground color, which changes to the most beautiful golden yellow. 2. Having no lively colors or marks of russet on the side next the sun, except those that are very much exposed, and which assume a slight tinge of red. 3. Having no covering of russet, but only slight traces of russety stripes. +ORDER II.--RED REINETTES.+ Having all the properties of the self-colored Reinettes, but of a pure red on the side next the sun, without any mixture of russet. +ORDER III.--GRAY REINETTES.+ 1. The ground color is green, changing to dingy dull yellow. 2. The coating of russet, or the russety patches, spread over the greater part of the fruit, are very conspicuous. 3. The side next the sun is often dull brownish or ochreous red. +ORDER IV.--GOLDEN REINETTES.+ 1. On the side next the sun they are washed or striped with beautiful crimson. 2. The ground color changes by keeping to a beautiful deep yellow. 3. Over the ground color, and the crimson of the exposed side, are spread light thin patches, or a complete coat of russet. CLASS V.--STREIFLINGE--STRIPED APPLES. 1. They are all, and almost always, marked with broken stripes of red. 2. These stripes are found either over the whole fruit, or only very indistinctly on the side exposed to the sun. 3. The stripes may be distinct--that is to say, truly striped; or between these stripes on the side next the sun the fruit is dotted, shaded, or washed with red; but on the shaded side the stripes are well defined. 4. The cells are regular. 5. They are of a purely sweet, vinous, or acid flavor. 6. They have not the same flavor as the Rose apples. 7. They do not decay, except when gathered before maturity. +ORDER I.--FLAT STREIFLINGE.+ 1. They have the bulge at the same distance from the eye as from the stalk, and are broadly flattened. 2. They are constantly half an inch broader than high. +ORDER II.--TAPERING STREIFLINGE.+ 1. They are broader than high. 2. They diminish from the middle of the apple towards the eye, so that the superior half is conical or pyramidal, and not at all similar to the inferior half. +ORDER III.--OBLONG OR CYLINDRICAL STREIFLINGE.+ 1. The hight and breadth are almost equal. 2. They diminish gradually from the base to the apex. 3. Or from the middle of the fruit they gradually diminish toward the base and apex equally. +ORDER IV.--ROUND STREIFLINGE.+ 1. The convexity of the fruit next the base and the apex is the same. 2. The breadth does not differ from the hight, except only about a quarter of an inch.
