The next subject to which I call your attention is the wonderful progress in the mechanical arts. Animals use the weapons nature has furnished, and those only--the beak, the claw, the tusk, the teeth. The barbarian uses a club, a stone. As man advances he makes tools with which to fashion his weapons; he discovers the best material to be used in their construction. The next thing was to find some power to assist him--that is to say, the weight of falling water, or the force of the wind. He then creates a force, so to speak, by changing water to steam, and with that he impels machines that can do almost everything but think. You will observe that the ingenuity of man is first exercised in the construction of weapons. There were splendid Damascus blades when plowing was done with a crooked stick. There were complete suits of armor on backs that had never felt a shirt. The world was full of inventions to destroy life before there were any to prolong it or make it endurable. Murder was always a science--medicine is not one yet. Scalping was known and practiced long before Barret discovered the Hair Regenerator. The destroyers have always been honored. The useful have always been despised. In ancient times agriculture was known only to slaves. The low, the ignorant, the contemptible, cultivated the soil. To work was to be nobody. Mechanics were only one degree above the farmer. In short, labor was disgraceful. Idleness was the badge of gentle blood. The fields being poorly cultivated produced but little at the best. Only a few kinds of crops were raised. The result was frequent famine and constant suffering. One country could not be supplied from another as now; the roads were always horrible, and besides all this, every country was at war with nearly every other. This state of things lasted until a few years ago.
