It is a good plan to keep seed potatoes in baskets or slatted boxes piled up in a cool cellar so that the air can circulate freely about them. Scab.—The rough blotches on the surface of potatoes are called scab. The disease is caused by certain spores or seeds, just the same as diphtheria or other contagious dis- eases are caused by germs. To prevent scab the spores of the disease must be destroyed. The spores may live over winter in the soil on which scabby potatoes were grown the year before. They may get into the soil with manure from animals that have been fed scabby potatoes, or they may. Figure oN.—A manure spreader be on the seed planted. The latter is the most common way of spreading the disease, and, as the seed is very easily treated to prevent scab, there is very little excuse for getting scabby potatoes in this way. Formaline is a Hquid which may be purchased at any drug store for from twenty-five to fifty cents per pint. A pint mixed with thirty-five gal- lons of water makes a solution which will destroy the scab spores on seed potatoes, if they are soaked in it for two hours. Treat for scab before cutting the potatoes. If cut first, some of the pieces may stick together and the spores in between will not be reached by the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Wilson, Archie Dell, 1875-; Wilson, E.
