The cultivation of the Plum is rendered nearly useless in most places by the attacks of the Curculio, or Plum Weevil. Every conceivable application to the trees has been tried without any satisfactory result. The only thing which will effectually save a crop in the districts infested by this insect, is to jar the tree in the morning or in cool days, first spreading sheets under the trees to catch the weevils, after which they may be burned. If this is begun as soon as the plums are formed, and persisted in every few days until they are ripe, a large share of the crop may be saved. This may be thought to be paying rather dear for a crop of plums, but it is really the only way it can be secured. Many years ago the crop of a plum orchard under our charge numbering over a hundred large trees, was saved by this process, while all other plums in the district where the jarring of the trees was not resorted to, were completely destroyed. This plan was recommended nearly half a century ago, and no other practicable method has since been presented. It has been recommended by some to plant the trees on the bank of a pond or running stream, and train them to overhang the water, also to pave or cement around the roots so that the insect cannot burrow, but these plans would be often impossible, and are useless. Trees upon stiff, clayey soils are more exempt from the ravages of the Curculio than those upon light ones, probably for the reason that the insect in the grub or larvae state cannot penetrate them so readily, as they must enter the ground to become perfect insects. The average distance at which the Plum may be planted is from ten to twelve feet. The following are distinct and fine sorts.
Color purple, with a rich blue bloom, size medium; flesh deep yellow, flavor of first quality; clingstone; ripens in August.
Color yellow, marbled with red next the sun; large size; flesh firm, sweet, and rich; freestone; ripens first of September.
A well known variety, rather small in size, but of exquisite flavor, color greenish-yellow, spotted with red on the sunny side; freestone; ripens early in August.
Of the largest size, color brownish-purple; flesh yellow, sweet, and finely flavored; freestone; ripens the last of August.
A. very old and well known sort, color golden-yellow with red spots next the sun; large, oval; rich and sweet yellowish flesh; clingstone; ripens middle of September.
