n as life enters matter, matter meets with a change of heart. It is lifted to another plane, the supermechanical plane; it behaves in a new way; its movements from being calculable become incalculable. A straight line has direction, that is mechanic

he same; life is a constant becoming; our minds and our bodies are

taken in and kindled and consumed by the fires of life. One can visualize all this and make it tangible to the intellect. Get your fire of life started and all is easy, but how to start it is the rub. Get your explosive compound, and something must break the deadlock of the elements before it will explode. So in life, what is it that sets up this slow gentle explosion that makes the machinery of our vital economies go-that draws new matter into the vortex and casts the used-up material out-in short, that creates and keeps up the unstable condition, the seesaw upon which life

We may fancy the infinitely little going through a cycle of evolution like that of the infinitely great, and solar systems developing and revolving inside of the ultimate atoms, but the Copernicus or the Laplace of the atomic astronomy has not yet appeared. The atom itself is an invention of science. To get the mystery of vitality reduced to the atom is getting it in very close quarters, but it is a very big mystery still. Just how the dead becomes alive, even in the a

ence is one of kind and not of degree. The vital transcends the mechanical, and the psychic transcends the vital-is on another plane, and yet without the sun's energy there could be neither. Thus are things knit together; thus does one thing flow out of or bloo
