THREE:In electricity great strides were made. Between the years 1705 and 1711 Francis Hawksbee published in the Transactions of the Royal Society several experiments, in which he had, for the first time, discovered the production of the electric spark by friction, and electrical attraction and repulsion. In 1720 Stephen Gray, a pensioner of the Charterhouse, published the result of his experiments on this subject, with a list of the substances which showed electricity under friction; and in 1732 he discovered the conducting property of non-electrical bodies. Before 1739, Dufray, keeper of the King's Garden at Paris, discovered the repellent power of two similarly-electrified bodies, and the attraction of these positively and negatively electrifiedor, as he termed it, possessing the vitreous and the resinous electricity. Cuneus and Lallemand discovered the mode of accumulating the electric fluid in what was called the Leyden jar in 1745. This discovery gave a new impetus to inquiry, and Nollet, in France, and Watson, in England, conceived the hypothesis of the jar being overcharged on one side and undercharged on the other. This growing perception of the positive and negative conditions of the electric fluid received confirmation from the experiments of Benjamin Franklin, in America. Franklin soon improved the Leyden jar into an electrical battery; and, in 1752, he proved the identity of electricity and lightning by his grand experiment of the kite. On this he recommended lightning conductors, which, however, were not used in England till ten years afterwards.He told her, directly, that he was passing through Arizona to hunt and to look to certain mining interests he held there. And he stayed, talking with her and her husband about the country and the towns and posts he had visited, until long after luncheon. Then Cairness, having to ride to the salt lick at the other end of the ranch, up in the Huachuca foot-hills, suggested that Forbes go with him.

FORE:241Still more inglorious were the proceedings of our fleet on the coasts of the Spanish-American colonies. Sir Chaloner Ogle joined Vernon in Jamaica on the 9th of January, 1741, and no time was to be lost, for the wet season set in at the end of April, which, besides the deluges of rain, is attended by a most unhealthy state of the climate. Vernon, however, did not move till towards the end of the month, and then, instead of directing his course towards the Havannah, which lay to the leeward, and could have been reached in three days, he beat up against the wind to Hispaniola, in order to watch the motions of the French fleet under D'Antin. It was the 15th of February before he learned distinctly that the French had sailed for Europe in great distress for men and provisions. Now was the time to make his way to Cuba; but, instead of that, he called a council of warthe resource of a weak commander,which was followed by its almost invariable result, a contrariety of advice. It was at length concluded that, as Admiral Torres had now sailed for the Havannah, and thus closed the opportunity for its attack, the fleet should take in wood and water at Hispaniola, and make for the continent of New Spain. On the 4th of March the fleet came to anchor in Playa Grande, to the windward of Carthagena.
