Weed has repeated his experiments of a year ago upon the destruction of the curculio on cherries and plums by means of london purple. It has now been proved by several observers that the adult curculio feeds upon leaves and fruits, and spraying with the arsenites has become a settled practice in many parts of the country. Mr. Weed's general conclusions must be convincing in the efficiency of this method of dealing with one of our worst pests: 1. "That about three-fourths of the cherries liable to injury by the plum curculio can be saved by two or three applications of london purple in a water spray, in the proportion of one ounce to ten gallons of water. 2. That a sufficiently large proportion of the plum crop can be saved by the same treatment to insure a good yield when a fair amount of fruit is set. 3. That if an interval of a month or more occurs between the last application and the ripening of the fruit, no danger to health need be apprehended from its use. 4. That spraying with the arsenites is cheaper and more practical than any other known method of preventing the injuries of this insect." The plum experiment of this season gave a remarkable illustration of the benefits of spraying.

The untreated trees "set a good crop of fruit, but it was entirely ruined by the curculio, not a single plum being left to mature. The crop in the orchard, however, was immense, one-half the fruit on many of the trees being artificially thinned, and then bearing so much that the limbs bent to the ground, and in some cases broke on account of the great weight".

Mr. Weed has made extensive experiments with that persistent pest, the striped cucumber beetle. This is one of the worst insects in the vegetable garden. "Fencing out the insects by covering the plants with some form of tent or gauze-covered frame" was the only entirely satisfactory method of preventing devastation. " The cheapest and most successful method employed is that of protecting each hill by a piece of plant-cloth or cheese-cloth about two feet square. This may be done simply by placing it over the plants and fastening the edges down by small stones and loose earth. It is better, however, to hold it up by means of a half-barrel hoop or a wire bent in the form of a croquet arch." Several styles of these coverings are figured. Other methods employed were the use of hen manure, cow manure, kerosene, carbolic acid, bisulphide of carbon, coal-soot, saltpeter, gypsum, Pyrethrum, slug shot and peroxide of silicates. Of these, peroxide of silicates "had a decided effect in preventing injury, and where the plants had been well started before being attacked saved them from destruction.

But it did not save them where the beetles were so numerous that they burrowed down to meet the sprouting plants".

The strawberry root-louse is a new insect which Mr. Weed names Aphis Forbesii, in honor of Professor S. A. Forbes, who first called attention to it. It has proved a serious pest in some parts of Ohio and Illinois, and is no doubt distributed elsewhere. The insects appear in great numbers, from July to the close of the season, "on the crowns and between the bases of the roots, at and just beneath the surface of the earth." The remedies appear to be rotation, and the disinfecting of plants taken from lousy plantations, by dipping the roots and crowns of the plants in kerosene emulsion.

The common currant worm is destroyed by hellebore, either in water or dry. Observations upon this pest indicate that when the bushes are stripped of their leaves the fruit crop of the succeeding year is apt to be light. The green leaf-hopper, which attacks the leaves of currants and. gooseberries, causing numerous small white spots to appear upon the upper surface, is easily held in check by Pyrethrum, applied before the insects are fully grown. Tobacco dust is also a good remedy.

The leaf-hopper insects often do great injury to the leaves of rose bushes, both out of doors and under glass. Mr. Weed finds that it is easily destroyed by applying Pyrethrum before the insects are fully grown. Tobacco dust or decoction, and whale-oil soap are also good.

The well-known cherry slug has been the subject of attention, and it is found that hellebore, either dry or in water; Pyrethrum, either dry or in water, and london purple, were all effective remedies.

Mr. Weed is one of the first to successfully apply fungicides upon a large scale for the purpose of combatting the dreaded potato-rot or blight. Two acres of potatoes were set aside for experiment. Bordeaux mixture was sprayed upon a part of the plantation on May 28, June 6, June 29 and July 16. To the Bordeaux mixture, london purple was added, one ounce to ten gallons, to destroy the potato bug. The conclusions of this experiment are of great importance: "1. A large proportion of the injury done by the potato rot can be prevented by spraying the vines with the Bordeaux mixture. 2. This treatment frequently diminishes the amount of scab affecting the tubers. 3. By adding london purple to the mixture, the same treatment may be made effective in preventing the injuries both of the rot and Colorado potato beetle".
