Averell Harriman and the Anaconda Copper Mining Co. bought control of the Georg von Giesche Heirs Mining Co. in Poland for $10,000,000 (TIME, June 14). They have just organized the Silesian-American Corp. to operate those Silesian properties as a subsidiary of Anaconda, the first important instance of an industrial enterprise of one 'country so overlording a similar one in another country. Last week Silesian-American sold $15,000,000 collateral trust bonds in Manhattan, to use in operations...
...produced the first printing blocks which, by printing one after the other with different inks, would reproduce a subject in its natural colors. Half Tones. The basis of half-tone printing as evolved by Mr. Ives lies in photographing the copy (subject) and transferring the negative to a copper or zinc plate treated with light-sensitive enamel; etching away the proper portions of the plate with acid; mounting the plate, inking and running it through a press. To produce a clear image (keep the ink from smearing) it is necessary to make the plate a mass of tiny points, whose...
...systems were used inside the buildings, that the high explosives had been jammed together in buildings much too close together. Nothing definite was said concerning the contention of Professor Michael Pupin of Columbia University, who stated that the lightning could have been held under control by the use of copper roofings connected by heavy copper strappings directly to the ground; or the belief of Inventor Hudson Maxim that subsurface magazines are essential to the prevention from spreading of explosions...
...committees investigating the disaster have not yet been published. Can their report explain why the Government did not place the magazines under ground, where danger would have been minimized? Can they discount the contention of Professor Pupin of Columbia University, as given by Hearst-Editor Brisbane, that sheet copper roofings connected by huge copper bands directly with wet earth would have frustrated even this "act of God?" The system of lightning rod protectors at Lake Denmark is obviously inefficient. The Government controls immense voltages of electricity at Niagara Falls; why have not engineers sought a method to control electrical attacks...
...multiplied speed of Western Union's new cable, 2,500 letters a minute, is to result from an improvement achieved in the cable itself after long experimenting to gain speed by improving sending and receiving instruments. Around the copper conductor of the 3,800-mile strand is wound a continuous strip of "permalloy" ribbon, an alloy of iron and nickel which conducts current very freely, permitting signals to be sent close together...
