We have no idea of how to cure a waste of nearly 90 per cent. in our motor-cars, from fuel to hond wheels, and our ideas of electric ity are still those of an attendunt at a miracle. Perhaps, in the far future, we may discover that as a phenomenon of time electricity is no more marvellous than a close- up slow-motion pleture of the hatching of an egg.
