The loss of feathers is probably due to the depluming mite. Dust well with buhach through the feathered portion of the bird and apply carbolated vaseline to the bare skin and the edges of the feathers where the insects work. Do this daily as long as needed. When vaseline is not on hand, a mixture of coal oil and sweet oil applied with a soft sponge squeezed nearly dry does as well. We would advise that you make a general cleaning and spraying of your poultry quarters, nest boxes, etc. Part IX. Pests and Diseases of Plants Control of Grasshoppers. This county is having trouble with the grasshoppers as are other counties. Would you kindly inform me what I could do to exterminate them on my young orchard? The best thing for grasshoppers is to fix up a lot of poison. This is made in the proportion of 40 pounds of bran, 2 pounds of molasses and 5 of arsenic, mixed together as a mash. They will take this wherever they find it, even when nice green leaves are close by, but it has to be kept moist. Grasshoppers can also be reduced by driving a "hopper doser" over ground where they are. This is made somewhat like a Fresno scraper, but is much longer and the bottom is covered with crude oil. When disturbed the hoppers jump up and fall into the oil. Besides the poison, you should also protect the trunk of the tree to prevent the hoppers from climbing up it. This can be done by applying tree tanglefoot, or putting on one of the tree guards that prevent climbing insects from passing up to the leaves. The combination of poison and tree guards will give you about all the protection you need. Sunburn and Borers. Please state the best remedy for keeping the borer out of young fruit trees. Sunburn can be prevented in many ways. The manufactured tree-protectors are good if they are light colored and are kept in place so that the sun does not scald above or below them. Wrapping spirally with narrow strips of burlap, torn from old grain sacks, from the base to the forking of the branches, is also good. A very effective and widely used method is to apply a good durable whitewash which may be made of 30 pounds of lime, 4 pounds of tallow and 5 pounds of salt, adding the salt to the water used in slaking the lime, stirring in the tallow while the slaking is in progress and hot, and then adding water to thin the wash so that it will work well with pump or brush. Gumming of Prune Trees. I write to ask for information concerning my prune trees. They are from two to six years old and the gum is exuding from them. As I notice the branches dying I cut them out, but this doesn't seem to save the tree. I would appreciate any information you can give me.
