NEW COTTON PICKING SHADE. The annexed engraving scarcely requires description as the purpose and advantages of the invention will be readily seen. Cotton picking at best a laborious occupation be comes irksome when conducted under a burning tropical sun; and a device which will afford to cotton pickers an efficient protection from the influence of strong sunlight and heat should receive attention. Such a device is shown in the accompanying engraving and it must prove beneficial to both laborers and employers for without a doubt more work can and will be done when a protection of this kind is afforded. The invention consists simply of a protective shade of cotton cloth mounted on a light frame provided with wheels which facilitate its movement along the rows of cotton to be picked. This invention was recently pa tented by Mr. J. C. Benthall of Schulenburg Texas. A Silver Fossil. Society of France describes an am monite of silver found in a silver mine at Caracoles South America by M. Fremier who was for some time director of the mines at that place. This remarkable specimen was found with a number of other ammonites belonging to the two ized with silver salts. The ammo nite in question however had been entirely replaced by chloride of silver which had been partially reduced to the metallic con dition. Light is thrown by this specimen upon the origin of the native silver which occurs in the Caracoles mines; for it is only fair to infer that this metal has in like manner been reduced from the state of chloride. PUMPING SYSTEM FOR HYDRAULIC PRESSES. There are two objections to the use of hydraulic presses as ordinarily arranged. One is that the press works at a uniform rate of speed throughout the entire distance tra veled by the platen and therefore of necessity works slowly; the other is that the press must be near the source of power to work to the best advantage. The accompanying engraving represents an improved system in which these objections are not found and whi
