The Curculio is the great enemy of the plum, and frequently of all smooth-skinned fruits, as the grape, nectarine, &c.
(1) Curculio, in the beetle-form, life-size. (2) Its assumed form when disturbed or shaken from the tree.
(3) Larva, or worm, as found in the fallen fruit. (4) Pupa, or chrysalis state, in which it lives in the ground.
Many remedies are proposed: making pavements, or keeping the ground hard and smooth, under the trees; pasturing swine and keeping fowls in the plum-orchard; syringing the whole tops of the trees four or five times with lime and salt water, or lime and sulphur-water—the proportions are not material, provided it be not excessively strong. It is recommended to apply with a garden-syringe. But, as few cultivators will have that instrument, they may sprinkle the mixture on the trees in any way most convenient. Salt, worked into the soil under plum-trees, is said to destroy this insect in its pupa state. At any rate, the salt is a good manure for the plum-tree. We know a remedy for the ravages of the curculio, unfailing in all seasons and localities—that is, to kill them: spread a cloth under the tree, and with a mallet having a head, covered with India-rubber or cloth that it may not injure the bark, strike the body and large limbs sudden blows, which will so jar them as to cause the insects to fall upon the cloth, and you can then burn them. Do this five or six times in the season, commencing when the fruit begins to set, and continuing till it becomes nearly full-grown. This is best done in the cool of the morning, while the insects are still; their habits of fear and quiet, when there is a noise about, are greatly in favor of their destruction by this method. This is somewhat laborious, but is a sure remedy, and will pay well in all plum-orchards, large or small. After two or three years of this treatment, there will be few or none of those insects left.
Uses of the plum are various. The fine varieties, well ripened, are a good dessert-fruit; for sweetmeats and tarts they are much esteemed; they are one of the better and more wholesome dried fruits. The foreign ones are called prunes, and are an article of commerce. With a little care, we can raise much better prunes than the imported. Like all fruits, they are better for quick drying by artificial heat. The French prunes, the process of drying which is minutely described by Downing in his fruit-book, are no better than our best varieties, quickly dried by artificial heat in a dry house, or moderately-heated oven. All dried fruit is much better for having become perfectly ripe before picking. It is a great mistake to suppose unripe fruit will be good dried.

Varieties are numerous, and many of them ought to be forgotten, as is the case with all other fruits. We give a small list, containing all the good qualities of the whole:—
