Stran 367 - The whole country, from San Francisco to Los Angeles and from the seashore to the base of the Sierra Nevada, resounds with the sordid cry of 'gold! GOLD!! GOLD!!!' while the field is left half planted, the house half built, and everything neglected but the manufacture of shovels and pickaxes...
Stran 10 - ... within the polar circles. Many ingenious hypotheses have been proposed to account for the warmer climate of earlier times, but are at best unsatisfactory, and it appears to me that the true solution...
Stran 43 - ... elastic force of the steam is the moving power, and this force is proportionably greater as the piston is more loaded and the steam more confined. If the bulb be now plunged into cold water, the steam in the cylinder is condensed, and a vacuum is produced below the piston, which is now forced down to the bottom of the cylinder by the pressure of the atmosphere. In this case, the moving power is acquired by the condensation of the steam, and the consequent production of a vacuum ; and this is...

Stran 10 - ... with great changes in the organic life of the globe. The air was doubtless at first unfit for the respiration of warm-blooded animals, and we find the higher forms of life coming gradually into existence as we approach the present period of a purer air. Calculations lead us to conclude that the amount of carbon thus removed in the form of carbonic acid has been so enormous, that we must suppose the earlier forms of air-breathing animals to have been peculiarly adapted to live in an atmosphere...
Stran 149 - Newspapers duly specifying it, two miners deep down in the shaft were engaged in putting in a shot for blasting: they had completed their affair, and were about to give the signal for being hoisted up, — one at a time was all...
Stran 367 - GOL'D!!! —while the field is left half planted, the house half built, and everything neglected but the manufacture of shovels and pick-axes, and the means of transportation to the spot where one man obtained one hundred and twenty-eight dollars' worth of the real stuff in one day's washing, and the average for all concerned is twenty dollars per diem...

"He arrived at Coloma on the 7th of March, and found the work at the mill going on as if no gold existed in the neighborhood. The next day he took a pan and spade and washed some of the dirt from the bottom of the mill-race in places where COLD DISCOVERY IN CALIFORNIA.
