CONTAGIOUS ANIMAL DISEASES.

Congress seems bound to act at once upon the question of protection to domestic animals from contagious diseases. The pressure brought to bear upon members is enormous, and cannot be ignored. The action of European States on swine importation from America, the restrictions on the landing of American cattle in England, and the strong effort being made there to prohibit their introduction altogether, the known existence of pleuro-pneumonia in several of the Atlantic States, the unceasing clamor of our shippers and growers of live stock, all conspire to open the eyes of the average Congressman to the fact that something must be done. Mr. Singleton, of Illinois, must be something above or below the average Congressman, if the report is correct that he does not believe pleuro-pneumonia exists anywhere within the borders of the United States, and that he is willing to back his non-belief by a thousand dollars forfeit, if an animal suffering from the disease can be shown him. The former owner of Silver Heels, and breeder of fine horses and cattle at his Quincy farm, must have his eyes shaded and his ears obstructed by that broad brimmed hat, that has so long covered his silvered head and marble brow. "The world do move," nevertheless, and pleuro-pneumonia does prevail in this country to such an extent as to furnish a reasonable excuse for unfriendly legislation abroad, and we gain nothing by denying the fact, the Allerton and Singleton assertions to the contrary, notwithstanding.
