The Radio Boys with the Forest Rangers; Or, The great fire on Spruce Mountain
There are two aspects of radio as a vital factor in saving life and property which are very vividly brought out in this interesting volume of the Radio Boys Seriesnamely its use in connection with the patrol work in detecting forest fires, and the regular international ice patrol in the dangerous waters of the north Atlantic. So splendidly have these two functions of radio been developed, that they have become accepted as commonplace in our lives, and it is only by such stories as The Radio Boys with the Forest Rangers that we are awakened to their importance. Another interesting account in this volume is the detailing of the experimental work recently carried out at the Schenectady broadcasting station, when the voice which was radiated through the ether was actually reproduced from an ordinary moving picture film. Just think of the marvel of this. The words of the speaker were photographed on a film, and held in storage for several weeks, before the streaks of light were re-converted into electric impulses, and then transferred into faithful reproduction of speech in a million homes. How great are the possibilities thus unfolded to the immediate future. Here we have a record that is better than that of the phonograph, because there will be no scratchiness from a needle in its reproduction to mar the original tones. ......Buy Now (To Read More)
