'1^ Mich as deterioration of soil, overpowering by dust and dirt, overcrowd- T^: 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 â that is, free from offensive odors â 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.âThis 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 different 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.âThis 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.âThis disease is mostly caused by want of air, changes of temperature, or excessive moisture; and therefore most frequently occurs among plants, cuttings and seedlings that are overcrowded. A little powdered, dry charcoal, or dry sand, sprinkled in among the plants, will help to keep it down, when the diseased ones should be care- fully remo\x-<l; and, if still too crowded, even
