...soot-laden white mist of great weight. Owing to the warmth of the ground and the consequent lighter pressure the fog descends from its chilly couch in the skies-that is, when there is no wind to blow it away-and covers the earth until the heat gradually dissipates it. Were it not for the soot, the mist would probably be dissipated by the surface heat as it descended...
...Edgar said: " Beyond Dawo we began to get startling confirmation of the havoc wrought by a mighty force from the bowels of the earth. At one village we found that every house had been leveled to the earth and quite half of the inhabitants killed...
Lord Rayleigh, distinguished English physicist, son of a former Chan cellor of Cambridge University, published a new estimate of the antiquity of the earth, of between two and three billion years, based on a study of the rate of decomposition of radioactive elements. This is vastly greater than any previous estimate, modern geologists having ranged between 100,000,000 and 1,600,000,000 years in their conjectures. All these estimates rest upon very slender assumptions, but that the age of the earth is to be reckoned in hundreds of millions of years is a scientific certainty. Lord Rayleigh...
...reputation. This is neither. Doubtless the work is uneven ? some of the branches on the tree are dead and others stunted ? of what collected works could that not be said ? But, on the whole, the volume displays a force and beauty truly of our own blood and earth, no longer merely in promise, but in achievement...
Mining companies of Butte, Mont., in cooperation with Daniel Harrington, supervising engineer of the U. S. Bureau of Mines, have reduced temperatures of over 100 degrees F. in low-level workings by as much as 15 degrees, through scientific ventilation. Temperatures in the depths of the earth increase from natural causes, but added to this the Butte mines have to contend with fires which have burned for many years in worked-out regions, one continuously since 1889. These fires feed on timber and combustible sulphides, and burning laterally and vertically, have so heated the adjacent rock...
