This Temiskaming and Northern Ontario Railway connects the Grand Trunk System at North Bay with the Canadian Government lines at Cochrane. The opening up of all this country has not only resulted in the exploiting of these famous mines, but has brought to knowledge the existence of the largest tract of pulpwood in the world. The belt of these forests extends from Ontario to Quebec and westward to the prairies of Manitoba, a thousand miles of almost unbroken woodland. The hydraulic mechanism used in prospecting for ore is one of the marvels of inventive genius. One man can operate the powerful lever that turns on a torrent of water against trees, huge stumps, vast rocks, and sends them rolling down the hillside. {138} All obstruction, indeed, the very hill itself, is washed down. The twentieth century will always stand out as a remarkable era for the invention of mechanism to harness and utilise power hitherto undreamt of for practical application. These inventions are securing the increasing spiritual liberation of man. When he is enabled to harness the powers of the ether; to send the lightning on his errands; to bridle a force that no man ever saw or touched; when he can cause the waves of the ether to serve his chariot wheels, he has indeed transformed the world in which he finds himself. There are rumours of a recent invention made by Mr. Asa Thurston Heydon in the Yukon that may largely revolutionise the mining industry. It was in the middle 'eighties that Mr. Heydon began studying the primitive divining-rod, the use of which he was inclined to believe was based upon some germs of scientific truth. He thought it possible that some natural law lay hidden in the garments of superstition. For thirty years he experimented and observed. This research has led him to what he believes is a series of discoveries, one of which is his invention called the clairoscope, which is the diviner for substances that are in the earth. Fitted with one or another substance attached, it turns to that which corresponds with the given thing attached. He calls the instrument the clairoscope and the result obtained the clairum. The clairum, Mr. Heydon explains, is the counterpart {139} of the spectrum. The latter is limited to the luminous, the former to the non-luminous, rays. The spectrum exemplifies one pole of the spherical organisation of energy, and the clairum exemplifies the opposite pole. Mr. Heydon's researches are based on his conviction that everything, organic and inorganic, from electrons to the mighty universe itself, is surrounded by a sphere; that these spheres blend and combine "in accordance with the laws of force-centres," but that in all combinations "they retain their identity as do rays of light." This interesting speculator holds that the non-luminous rays are constant, changing only from attraction to repulsion, and that they are the radii of the spheres. He believes that the distinctive energy that
