K ^:es of ^ljlJSTTs. ,ISEASE seldom takes hold of plants while surrounded by such circumstances as are favorable to their full development; ordinarily it springs from neglect, but occasionally from accidental causes, such as deterioration of soil, overpow^ering by dust and dirt, overcrowd- ing, and the like. The leaves, being the lungs of the plants, must be sedulously guarded from becoming clogged with dust, deranged by insects, or scorched by exceeding heat, all which are prolific sources of disease. Everything about the roots and rootlets should be sweet—that is, free from oflFensive odors—and composed of substances that are easily dissolved by rain or water; for the rootlets, being the mouths, will refuse unwholesome food, and the plant will soon sicken. Mildew.—This is a fine, minute, white, fungus growth, not peculiar to plants, but affecting them as well as other things where the conditions are favorable. It generally arises in plants where an unequal temperature or distribution of moisture prevails in the diiferent parts, as when any one portion is too dry, too wet or too cold. It is most easily removed by applying through a common pepper-box a very light dusting of flour of sulphur on the parts affected, and prevented by maintaining equal conditions in the various parts of the plant. Blackrust.—This is a black, moist, fungus growth that is produced mostly by exces- sive moisture and the absence of the necessary amount of warmth. The remedy is the same as for mildew, with the addition of securing greater heat. Damping Off.—This disease is mostly caused by want of air, changes of temperature, or excessive moisture; and therefore most freque
