FOREWORD
The development of radio telephony is still in its infancy at this time of writing in 1922. And yet it has made strides that were undreamed of in 1918. Experiments made in that year in Germany, and by the Italian Government in the Adriatic, enabled the human voice to be projected by radio some hundreds of miles. Today the broadcasting stations, from which nightly concerts are sent far and wide across the land, have tremendous range.
Estimates compiled by the various American companies making and selling radiophone equipment showed that in March of 1922 there were more than 700,000 receiving sets installed throughout the country and that installations were increasing so rapidly it was impossible to compute the percentage with any degree of accuracy, as the gains even from week to week were great.
When you boys read this the problems of control of the air will have been simplified to some extent. Yet at the beginning of 1922 they were simply chaotic. Then the United States Government of necessity took a hand. The result will be, eventually, that certain wave lengths will be set aside for the exclusive use of amateurs, others for commercial purposes, still others for governmental use, and so on.
In this connection, you will note that in the story Jack Hampton's father builds sending stations on Long Island and in New Mexico. This is unusual and requires explanation.
The tremendous growth of amateur receiving stations is due in part to the fact that such stations require no governmental license. A sending station, on the other hand, does require a license, and such license is not granted except upon good reasons being shown. It would be natural for the government, however, to give Mr. Hampton license to use a special wave length--such as 1,800 metres--for transoceanic radio experiments. Extension of the license to the New Mexico plant would follow.
THE AUTHOR.

DIRECTIONS FOR INSTALLING AN AMATEUR RADIO RECEIVING TELEPHONE
In order that the boy interested in radio telephony may construct his own receiving set, the Author herein will describe the construction of a small, cheap set which almost any lad handy at mechanics can build. Such a set should be sufficiently powerful to permit of successfully picking up the concerts and other programme entertainments being broadcasted frequently by stations throughout the country.
Two drawings are given herewith which will enable boys to visualize the appearance of the set, and will be of aid in following instructions.
Referring to Figure 1 let us examine first the construction of the receiving inductance marked L. The latter is shown in detail in Figure
