The fowl's head seems feverish, and soon all the feathers come otF. Mine- were so, and I said I would kill or cure ; so I mixed tip a half pail of soft feedand put in a large handful of salt. I went nut next morning to see what the result was, and I found them all alive but very thirsty. I gave them some water, and the next evening more salt. My hens all feathered out mi their heads, and they stopped eating each other's feathers, a habit hard to break.—'ye. Ii urat .-:.,,dh*r,ier.
