THE Scientific American FOR 1870

Cash Prize and Premium List

This Illustrated Weekly Journal of

Practical Information, Art, Science, Mechanics, Invention, Chemistry, and Manufactures--Entered its Twenty-fifth Year on the 1st of January.

The SCIENTIFIC AMERICAN stands at the head of Industrial Journals of the world in point of Circulation and Influence.

Every number has Sixteen Imperial pages, embellished with Engravings of New Inventions, Machinery, Tools for the Workshop, House, and Farm, also Public Buildings, Dwelling Houses, and Engineering Works.

The Illustrated Department of the SCIENTIFIC AMERICAN is a very striking feature, and has elicited the praise of the Press and all articles appearing in its columns are written in a popular and instructive style.

To Inventors and Mechanics the SCIENTIFIC AMERICAN has special value and interest, from the fact that it furnishes an Official List of Patents issued, with copious notes of the principal American and European Patents.

The Publishers offer the following

SCHEDULE OF CASH PRIZES.

For the fifteen largest lists of names sent in before February 10, 1870, the following Cash Prizes will be given:

$300 FOR THE FIRST LIST.

It contains the following group of illustrious inventors, namely: Prof. Morse, Prof. Henry Thomas Blanchard, Dr. Nott, Isaiah Jennings, Charles Goodyear, Jos. Saxton, Dr. W. T. Morton, Erastus Bigelow, Henry Burden, Capt. John Ericsson, Elias Howe, Jr., Col. Samuel Colt, Col. R. M. Hoe, Peter Cooper, Jordan L. Mott, C. H. McCormick, James Bogardus, and Frederick E. Sickles. The likenesses are all excellent, and Mr. Sartain, who stands at the head of our American Engravers on Steel, in a letter addressed to us, says "that it would cost $4,000 to engrave the plate now," which is a sufficient guarantee of the very high character of the Engraving as a work of art.
