THE REDWOOD oess to the refinement of the women of the Thirteenth Century. The passion of love for the ideal of a woman, as distinguished from any affection for the woman herself, was a power that fanned the distinct spark of early genius into the leaping flame of universal and immortal intensity — Dante will be read as long as Christi- anity survives. But Dante, for all his nobility of heart and loftiness of mind, was not a perfect man by any means ; his invect- ive utterances from exile against the Sovereign Pontiffs of his time and those responsible for his expatriation from his Florence can be overlooked, yet cannot be justified. For all that, although tossed about cruelly by his misfortunes, he remained courageous in spirit and strong in character, while his energies remained active and his cour- age unshaken. Dante lived his life as his conscience directed him, and we are not surprised to learn that he practised his religion in an exemplary and consistent manner. He recognized two guides to assist him in successfully traversing the span of life; the monarchical government of Rome he regarded as the most perfect form of civil rule, while in the higher life he turned to the Pope, the Vicar of Christ and successor of St. Peter, to lead him in the path of righteousness. Both Church and State he maintained, were ordained by Heaven to guide him to his two-fold end. Dante ' s chosen work in life is high- ly becoming the man ; he proceeded up- on the conviction that sin was the prime cause of disorder in the universe and waged an audacious and inexora- ble fight against its corrupting influ- ences. In his Divine Comedy the message and admonition are contained, advising humanity to look to the end that all may be well with them and their posterity. Never did a poem jump into such favor at the death of its author or en- gage the public attention more power- fully. This can be attributed, not alone to its intrinsic excellence, but be- cause it dealt freely and audaciously with the high characters of the time. It gripped the curiosity of the age, for many saw in it his neighbor or kins- man painted in his true coloi s of honor or infamy. Again, the subtle allegory pervading it, the striking allusions and originality of metaphoric language, were factors that drew a hungry legion of admirers. In later years as the mills of civili- zation ground out new conceptions and interpretations of life, the philosophy of Dante was often misunderstood. Readers saw only the grim and fore- boding mask of the man and unwitting- ly thought not to peer beneath. Few poets, perhaps, ever had their writings subjected to such varying criticism. Common men, not under- standing him, manifested only a luke warm interest. Education, with eyes solidly fixed on Shakespeare, Milton and Homer, had scarcely taken the trouble to flit the pages of Dante ; but the masters of all times have pro- nounced his name always with the deepest respect and reverence. At last in our time it is gratifying to find that the world has shoAvn an in- clination to follow the lead of these masters, so that the Poet of Flor- ence and the ideal of Christendom may come into his own.

Radio Telephony Francis B. Tinney RESUMABLY the foremost achieve- ment of modern science in the last twenty-five years, with the excep- tion of the air- plane, is Wire- less Communication; and in the past ten years, the development of the Radio Telephone. The desire of man to communicate with another at a dist- ance is probably as old as man himself, but the first human to accomplish any noteworthy success was Samuel F. Morse. His invention, the line tele- graph, is also the basis of the present day trans-oceanic cables. The next person to make a noteable adva nce in the field of electrical communication was the famous Alexander Graham Bell, who found a means of modulation by which the voice could be transmit- ted electrically over great distances and reproduced into sound again. Mod- ulation causes electric currents to fluc- tuate in amounts proportional to the sound vibrations. The first discovery of the underlying principle of Wireless Telegraphy was made in 1888 by Heinrich Hertz, a Ger- man Physicist, who found and determ- ined the velocity of electrical oscilla- tions, from which fact they received the name Hertzian Waves. It remain- ed, however, for Marconi, in 1896, to realize the importance of Hertz ' s dis- coveries and put them to use in a very crude wireless telegraph system. This first set, although very cumbersome and bulky, was capable of covering a distance of only about three miles. About 1905, after many improve- ments in radio equipment, Lee de For- est, an American Scientist, invented the three element Audion Tube, which will be explained later, and made Radio Telephony practical. Before leaving the Audion Valve for the present, it might be well to state that it has a three fold role: that of detection, of amplification, and of setting up pure, constant amplitude oscillations. Before proceeding deeper into the subject a few principles of Physics will be appropriate in order that the reader may obtain a better conception of the topic. Radio Communication of any form is conducted by Ether waves. These will be understood by an analogy. Should we drop a pebble in a pool of still water, waves will be propagated and extend radially from the point of the disturbance. Each wave consists of a peak and a hollow, the distance be- tween two adjacent peaks or hollows is the wave length. The number of these waves per second is called the frequen- cy. If the distance covered by a cer- tain number of waves in a second is kept constant, as in the case of Wire- less Communication, and the frequency increased, it is obvious that the wave length must be decreased in an inverse proportion. Similarly, if the frequency
