Three separate dispatches from Vienna combine to dispel all doubt as to what sewing machine has won the first honors of the great Exposition. The first was a special to the New York press on Monday, and was as follows:

Vienna, August 15, 1873,

The Wilson shuttle sewing machine was awarded the grand prize at the Vienna Exposition for being the best sowing machine.

The second was the regular Associated Press report, compiled from a long special to the New York Herald, in which the "Wilson Sewing-Machine of Cleveland, Ohio," was named as among the exhibitors which received "medals for merit," the highest class of premiums awarded at the Exposition. All other sewing-machines will receive simply an award for progress.

The third was a. private cable telegram received yesterday from Vienna by Mr. Wilson himself, which was as follows:

Vienna, August 19,

You have received Jive medals - two for merit and three co-operative.

The meaning of this is that the Wilson machine has received the grand medal as the best sewing-machine, and a second medal as the machine best manufactured - that is, embodying the best mechanical workmanship. Besides these, Mr. George W. Baker, Assistant Superintendent of the Wilson Sewing machine Company, receives a special medal for excellence of workmanship on the machine; Mr. Williams of this city receives a medal for the best sewing on leather, done by the Wilson; and Miss Brock and Miss De Lussey receive still another medal for best samples of family sewing and embroidery, done on the Wilson machine. This sweeps the entire board. Not only has the Wilson sewing machine been pronounced the most capable and efficient sewing machine in the world, but its work, on both dry goods and leather, is pronounced superior to that of all other machines. This verdict at a World's Fair, where all the leading sewing machines of both continents have competed before a thoroughly competent committee for more than three months, is the most complete triumph ever won by a sewing machine. We congratulate Mr. Wilson, we congratulate Cleveland on this admirable result.

The people of the United States can henceforth be assured that in buying the Wilson machine for $20 less than any other first class sewing machine is offered, they are purchasing the best sewing machine ever offered to the public. It is the people's own machine, made to do the people's work,, and offered at a price which every one can afford to pay. It is the people's machine which has won this triumph; the judgment of the Vienna Committee only confirms the verdict that the masses had long ago reached by actual experience. - Cleveland Daily Leader, August 20.
