The best protection of purchasing power is a policy of full production and full employment opportunities. Obviously, an employed worker is a better customer than an unemployed worker. There always will be, however, some frictional unemployment.
Under the general principle that the local slope of a river is the result and measure of the resistance of its bed, it is evident that a narrow and deep stream should have less slope, because it has less frictional surface in proportion to capacity; i.e., less perimeter in proportion to area of cross section.
Clark grumbled something about their being meteor-stones, whose ferruginous substance had been lured by the magnetic Pole, and kept from frictional burning in their fall by the frigidity of the air: and they quickly ceased to interest our sluggish minds, except in so far as they obstructed our way.
If it were not for the air surrounding it and other frictional losses, the spring would vibrate for a very long time as the stored up energy and the energy of motion would practically offset each other and so the energy would not be used up.
But George says that's what they said, for the aurora borealis is caused by the earth a-rolling around and rubbing the air just as the sparks is caused by stroking the cat's back. "And George he says that this here frictional electricity is the only kind that'll cure pain.
It is all very puzzling. Monday, May 22. The 'go cart' consists of a framework of steel tubing supported on four bicycle wheels. The surface of the floes carries 1 to 2 inches of snow, barely covering the salt ice flowers, and for this condition this vehicle of Day's is excellent. The advantage is that it meets the case where the salt crystals form a heavy frictional surface for wood runners.
The reference letters in each case indicate identical parts: A being the chalk drum, B the paper tape, C the auxiliary cylinder, D the vibrating arm, E the frictional pad, F the spring, G and H the two contacts, I and J the two wires leading to local circuit, K a battery, and L an ordinary telegraph key.
The elasticity of the air and its frictional inertia when running in the form of wind cause the current to proceed on its course after a very slight check, which in point of time is momentary and in its effects almost infinitesimal.
Later a man named Dyer, of New York, invented a system of sending messages by a single wire, and of causing a record to be made at the receiving office by means of a point passing over litmus paper, which the current was to mark by chemical action, the paper passing over a roller or drum during the operation. The battery for this arrangement was also frictional. They knew of no other.
And then I said I was a member of the Baptist Society, and she said at once she would read Barclay on the errors of that sect; but I insisted on being heard, and I explained to her that I got into this trouble by trying to cure William Jones by frictional electricity, and she said: 'Thee has an ingenious and fruitful mind to invent such a story.
