The Detectives Partner

"Oh, Dad! I've made a new set," cried Tom, as he entered the dining room.

"That so, Son?" replied Mr. Pauling interestedly. "Seems to me you boys do nothing but junk your sets as fast as you make them and build others. Does this one work better than the last?"

"It's a peacherino!" declared Tom enthusiastically. "Just wait till you see it and listen to the music coming in."

"I'll come up after dinner," his father assured him. "Let me know when the fun begins. I've some papers to go over in the library first."

Throughout the meal the talk was all of radio, in which Tom and his boy friends had become madly interested and in which Tom's father and mother had encouraged him.

"Go to it, Tom," his father had said when the boy had glowingly expatiated on the wonderful things he had heard on a friend's instrument and had asked his father's permission to get a set. "I'm glad you're interested in it," he had continued. "It's going to be a big thing in the future and the more you learn about it the better. But begin at the beginning, Tom. Don't be satisfied merely with buying instruments and using them. Learn the whole thing from the bottom up and use your mechanical ability to build instruments and to make improvements. Wish they'd had something as fascinating when I was a kid."

Tom had lost no time in availing himself of his father's permission, and of the roll of bills which had accompanied it, and there was no prouder or more excited boy in Greater New York than Tom Pauling when he triumphantly brought home his little crystal receiving set and exhibited it to his parents.

"I can't understand how a little box with a few nickel-plated screws and some knobs can do all the things you say," was his mother's comment. "But then," she added, "I never could understand anything mechanical or electrical. Even a phonograph or an electric light is all a mystery to me."

Mr. Pauling looked the instrument over carefully and listened attentively to Tom's graphic explanation of detectors, tuners, condensers, etc.

"H-m-m," he remarked, "I guess I'll have to take a back seat now, Son. You evidently have a pretty good grip on the fundamentals. Sorry I can't help you any, but it's all Greek to me, I admit."

"Oh, it's all mighty simple," Tom assured him. "Frank's coming over this afternoon and we're going to put up the a?rial and then you and mother can hear the music and songs from Newark to-night."

But despite the fact that Mrs. Pauling declared it the most remarkable thing she had ever seen or heard, and his father complimented him, Tom was far from satisfied with his first set. He didn't like the idea of being obliged to sit with head phones clamped to his ears in order to hear the music from the big broadcasting stations; he felt that it was mighty unsatisfactory for only one person to hear the sounds at one time and he soon found that despite every effort he was continually interrupted by calls and messages from near-by amateur stations.

Being of a naturally inventive and mechanical mind and remembering his father's advice to try to improve matters, he spent all his spare time studying the radio magazines, haunting the stores where radio supplies and instruments were sold and arguing about and discussing various devices and sets with his boy friends. Hardly a day passed that he did not arrive at his home carrying some mysterious package or bundle. Accompanied by his chum Frank, from the time school was over until late in the evening he kept himself secluded in his den while faint sounds of hammering or of animated conversation might have been heard within.

"What's all the mystery, Son?" his father had asked on one occasion. "Going to spring some big invention on an unsuspecting world?"

Tom laughed. "Not quite, Dad," he replied, "but I'm going to give you and mother a surprise pretty soon."

When at last all was ready and his parents were invited to Tom's holy of holies they were indeed surprised. Upon a small table were various instruments and devices and a seeming tangle of wires, while, tucked away on a bookshelf, was the little crystal set which had so recently been Tom's pride and joy.

And still greater was their surprise when, after busying himself over the instruments, the faint sounds of music filled the room, coming mysteriously from the apparent odds and ends upon the table.

"It's all homemade," Tom had explained proudly. "But it works. Frank and I rigged it up just as an experiment. Now I'm going to reassemble it and put it in a case and have a regular set."

"Wait a minute, Tom," his father had interrupted. "You'll have to explain a bit. If that lot of stuff can give so much better results than the set you bought, why didn't you make it in the first place, and what's the difference anyway?"

"Well, you see, Dad," Tom tried to explain, "I had to start at the bottom as you said and a crystal set's the bottom. This is a vacuum tube set. Those things like little electric lights are the tubes and they're the heart of the whole thing, and I've a one-step amplifier and that has to have another tube. I didn't have enough pocket money to buy everything so Frank lent me some of his. You see it's this way--"

"Never mind about the technicalities," laughed his father. "As I said before, go to it. Get what you need and keep busy. It's a fine thing for you boys. Now turn her on again, or whatever you call it, and let's hear some more music."

From that time, Tom's progress was rapid although, as his father had jokingly remarked, the boy's chief occupation appeared to be building sets one day only to tear them down and reconstruct them the next.

Tom's room had assumed the appearance of an electrical supply shop. Tools, wire, sheet brass, bakelite, hard rubber knobs, odds and ends of metal, coils and countless other things had taken the places of books, skates, baseball bats and papers, and the fiction magazines had given way to radio periodicals, blue prints and diagrams. Mrs. Pauling was in despair and complained to her husband that Tom was making a dreadful mess of his room and expressed fears that he might get hurt fooling with electricity.

"Don't you fret over that," her husband had advised. "Tom and his friends are having the time of their lives. As long as they are learning something of value, what does it matter if they do keep his room in a mess? Besides, it's clean dirt you know-and it's orderly disorder if you know what I mean. They're exploring a new world and haven't time to look after such trifles as having a place for everything and everything in its place. That will come later. Just now they are fired with the zeal and enthusiasm of great inventors and scientists. We mustn't interfere with them-such feelings come to human beings but once in a lifetime. I consider this radio craze the best thing for boys that ever occurred. It gives them an interest, it's educational, it keeps them off the street and occupies their brains and hands at the same time. Do you know, if I didn't have my time so fully occupied, I believe I'd get bitten by the bug myself. Besides, they may really discover something worth while. I was talking to Henderson of our staff to-day-he had charge of our radio work during the war-and he tells me some of the best inventions in radio have been made by amateurs-quite by accident too. I expect Tom knows that and that's what makes the kids so keen on the subject-it's a wonderful thought to feel you may stumble on some little thing that will revolutionize a great science at any moment."
