"The season has been specially characterized by the occurrence of several widespread and destructive contagious diseases among insects. Elaborate studies of these have demonstrated that they are due to bacteria and other parasitic fungi, that these disease germs may be artificially cultivated outside the bodies of the insects, and that when sown or sprinkled upon the food of healthy individuals, the disease follows as a consequence. We have in this the beginning of a new method of combating insect injuries which promises some useful results." Illinois Central Railroad. The elegant equipment of coaches and sleepers being added to its various through routes is gaining it many friends. Its patrons fear no accidents. Its perfect track of steel, and solid road-bed, are a guarantee against them. FARM IMPLEMENTS, Etc. NICHOLS & MURPHY'S CENTENNIAL WIND MILL. [Illustration of a windmill] Contains all the valuable features of his old "Nichols Mills" with none of their defects. This is the only balanced mill without a vane. It is the only mill balanced on its center. It is the only mill built on correct scientific principles so as to govern perfectly. ALL VANES Are mechanical devices used to overcome the mechanical defect of forcing the wheel to run out of its natural position. This mill will stand a heavier wind, run steadier, last longer, and crow louder than any other mill built. Our confidence in the mill warrants us in offering the first mill in each county where we have no agent, at agents' prices and on 30 days' trial. Our power mills have 25 per cent more power than any mill with a vane. We have also a superior feed mill adapted to wind or other power. It is cheap, durable, efficient.
