C.W. and I.C.W. The Proper Circuit to Use in a Transmitter Value of the Constants Are Given in the Text. Fig. 1, By CHARLES DAVISON Now that standard power tubes are available for amateur use it is probable - that considerable experimental work will be done In building tube transmitters. The writer has bad a number of years experience in the design and operation of continuous-wav- e equipment and hopes to provide some practical Information for the amateur who is about to build hls first C.W. set. We shall first consider a circuit that la to be used solely for straight C.W. and LC.W. (Interrupted continuous wave) transmission. Obviously any circuit that eliminates (he expensive motor generator or rectifier tubes will quickly find favor. A properly built transmitter has these advantages and at the same time will give as great or greater range than more complicated systems. Working on the basis that two of the power tabes are to be used s oscillators, the following units are required : A transformer giving a secondary voltage of 700 to 800 with a tap brought out at the midpoint of the By ELMO SCOTT WATSON NE May day some five years ago a little group of notables, among them Franklin K. Lane,' secretary of the Interior, Gov. George W. P. Hunt of Arizona and Bishop Julius W. Atwood of the church of Episcopal Arizona, assembled at Maricopa Point on the rim of the Grand Canyon and, with Harry R. Trlttle, son of former Gov. F. A. Trit-tias master of ceremonies, formally dedicated a massive monument of native rock, bearing a bronze tablet with a portrait In and these words : Erected by the Congress of the United States to Maj. Wesley Powell, first explorer of the Colorado river, who descended the river with his In row boats, traversing the party I gorge beneath this point August 17, 1869, and again September 1, 1872." This tardy honor was paid to the leader of thnt little band of men who a half century before had braved the treacherous red torrent sweeping along between Its rocky walls 5,000 feet below where their memorial now stands and had accomplished an undertaking which men had called Im' , possible. The other day, another monument wps erected to the Intrepid explorer, but this time It was far from the scene of exploit which brought him fame. It was on the campus of an institution of higher learning in the Middle West, Illinois Wesleyan University at Bloomington, 111., of which Powell was an alumnus, and from which he resigned his position on the faculty in 1868 to set out on his great adventure In the Southwest. He never lost interest in his Alma Mater, and In later years when he was holding .Important scientific positions under the United States government he made numerous contributions to its museum, 'which was named in his honor. So It was particularly appropriate that this years senior class at Wesleyan In choosing a class memorial to leave at the university decided upon a monument to the man who not only gave the flcst scientific Impulse to that Institution, but who often later guided The and quickened that interest. marker stands at the south entrance of the main building of the university and bears this Inscription: e, bas-reli- . In honor of Major J. M. Powell, professor of natural science, Illinois Wesleyan University, 1865-Explorer of the Grand Canyon of the Colorado, Erected by the Class of 1923. 8. 1867-187- 2. The feat which provided the Inspiration for the erection of these memorials in widely separated parts of the country was one of the most brilliant In the history of American exploration and Indirectly it gave to the American people one of their finest national parks. Today the citizen of the United States who has not seen the Grand canyon has not even begun to See America First, but up to the time of Powells exploration of the Colorado river not one American In a hundred thousand had gazed upon Its wonders. The first white man to view the chasm was Don Garcia Lopez de Cardenas, a lieutenant of Coronado, who visited it about 1540, long before the first English-speakinpeoples had settled on the Atlantic coast. But for the next 250 years, he canyon, hidden away In an almost Inaccessible part of the country and awe-inspiri- g surrounded h.v a vast desert, attracted little attention. It may have been visited bv some of the wandering free' trappers who were pushing their way Into every comer of the West within a score of years after the Louisiana Merry Persian Monarch j jwrrcus m&jerzazr zvksxx. purchase had given the young republic of the United States a vast empire, but It was not until March, 1826, that there is any authentic record of another white mans eyes resting upon It In that month James O. Pattle, who with his brother Sylvester Pattle made the first overland trip to California (IncidentUy antedating General Fremont, the famous Pathfinder," by nearly two decades), stood upon the rim of the canyon. He came not to admire, as Is the custom of travelers today, but to curse the precipitous walls because they prevented his crossing the Colorado In his westward Journey. Besides there were no beaver to be trapped on the arid plateau above the canyon and Patties party was a little band of trappers. So they followed along the east bank of the river for 300 miles before they could find a crossing. Patties visit Is one of historical record but no more, for the existence of the canyon did not receive official recognition until 1857, when It was mentioned In a report on the navigability of the Colorado made to the War department by Lieutenant Joseph C. Ives (later a colonel in the Confederate army). Nor was much more heard of it for another ten years and Powell determined to dispel some of the mystery surrounding the gigantic gorge by exploring the Colorado river and making scientific studies of that region. So he resigned his professorship at Illinois Wesiyan and, backed by that institution and the Chicago Academy of Sciences, he departed for the West to The whole organize his expedition. story of that thrilling trip Is too long to be told here. Fortunately its perils and achievements have been adequately chronicled by Frederick S. Dellenbaugh, one of the three surviving members of the party and now an author of note, In his book, Breaking the Wilderness. Late In May, 1869, Powell assembled his party in Wyoming on the Green river, which, by junction with the Grand river, forms the Colorado, and started out with these ten men In four open boats to float down the river. Long before they reached the Grand canyon they had lost one of their boats and with It most of their Instruments and a large part of their provisions. They had set out with ten months, supplies but they were now reduced to a ten days supply of musty flour, a few dried apples and an abundance of coffee. Undaunted by the experiences they had already gone through they entered the canyon and on August 17 floated past the point where their memorial now stands. For the next two weeks they struggled with the raging river, in constant danger of death from whirlpools and falls. They lost another boat, but kept on. Two or three days before they succeeded In passing through the canyon three of the party became disheartened and abandoned the expedition, only to meet their deaths at the hands of hostile Indians. This was the only loss of life on the whole trip of three months. Powell was not satisfied with Just one trip through the canyon and three years later he repeated the experiment, this time with less privation than his party had experienced on their pioneer Journey. Powells exploits aroused popular Interest In the grand canyon. In 1886 trans-Mississip-pi In turn would receive a push, with the result that after a swift descent she landed with a huge splash In the water beneath.
