Note.—The above List of Claims indicates that the times have not materially affected inventive genius, and why should they ? On the contrary, we have noticed in yaar3 gone by, that when trade generally was most depressed, and mechanics wcrQ out of employment, and consequently had the smallest incomes, thon it was tliat the business of the Patent Office was the greatest, thus proving the oTd adage that "Necessity ia the mother of Invention." No man knows what he can accomplish until placed in some emergency, out of which he is obliged to work his way. It is so with many wh hive recently secured patents. They did not know they had the talent foi1 inventing until necessity compelled them to do something fora livelihood, and as they were out of employment, they fortunately took the advice they had often read in our columns, and made an invention, got it patented, sold rights, and are now in a position to snap their fingers at the hard times. In the foregoing list, we recognize the names of twenty-tubee—more than one-third of the entire number—whose patents were secured through the Scientific American Patent Agency.
