DOWNLOAD EBOOK →Excerpt from Inventions in the Century IN treating of the subject of Inventions it is prop er to distinguish them from their scientific kindred Discoveries. The history of inventions is the history of new and useful contrivances made by man for practical purposes. The history of scientific discoveries is the record of new things found in Nature, its laws, forces, or materials, and brought to light, as they exist, either singly, or in relation, or in combination. Thus Galileo invented the telescope, and Newton discovered the law of gravitation. The practical use of the invention when turned to the heavenly bodies served to confirm the truth of the discovery. Discovery and invention may be, and often are, united as the soul is to the body. The union of the two produces one or more inventions. Thus the in vented electro-telegraph consists of the combina tion of discoveries of certain laws of electricity with an apparatus, by which signs are communicated to distances by electrical influence.

Invent and experiment with seeding machines. The nineteenth century found the great mass of farmers everywhere sowing their wheat and other grains by throwing them into the air by hand, to be met by the gusts of wind and blown into hollows and on ridges, on stones and thorny places.
