himself, was almost ready to admit this, when, a week later, he seemed to be no nearer a solution of the problem than he was at first. He had tried everything he could think of, and he had Eradicate and Koku, the giant, almost distracted, by making them stay in small telephone booths for hours at a time, while the young inventor tried to get some reflection of one face or the other to come over the wire.

Koku finally got so nervous over the matter, that he flatly refused to "pose" any longer, so Tom was forced to use Eradicate. As for that elderly man of all work, after many trials, all unsuccessful, he remarked:

"Massa Tom, I reckon I knows what's wrong."

"Yes, Rad? Well, what is it?"

"Mah face am too black--dat's de trouble. You done want a white-complected gen'man to stand in dat booth an' look at dat lookin' glass plate. I'se too black! I suah is!"

"No, that isn't it, Rad," laughed Tom, hopelessly. "If the thing works at all it will send a black man's face over the wire as well as a white man's. I guess the truth of it is that you're like Koku. You're getting tired. I don't know as I blame you. I'm getting a bit weary myself. I'm going to take a rest. I'll send for another kind of selenium crystals I've heard of, and we'll try them. In the meanwhile--I'll take a little vacation."

"Get out my small airship, Rad, and I'll take a little flight."

"Dat's de way to talk, Massa Tom," was the glad rejoinder.

"I'm going over to see Mr. Damon, Father," announced Tom to Mr. Swift a little later, when his speedy monoplane was waiting for him. "I haven't seen him in some time, and I'd like to get at the truth of what Mr. Halling said about Mr. Damon's fortune being in danger. I'll be back soon."

"All right, Tom. And say--"

"Yes, Dad, what is it?" asked Tom, as he paused in the act of getting in the seat.

"If he wants any ready cash, you know we've got plenty."

"Oh, sure. I was going to tell him we'd help him out."

Then, as Koku spun the propeller blades, Tom grasped the steering wheel, and, tilting the elevating rudder, he was soon soaring into the air, he and his craft becoming smaller and smaller as they were lost to sight in the distance, while the rattle and roar of the powerful motor became fainter.

In a comparatively short time Tom had made a successful landing in the big yard in front of Mr. Damon's house, and, walking up the path, kept a lookout for his friend.

"I wonder why he didn't come out to meet me?" mused Tom, for usually when the eccentric man heard the throbbing of Tom's motor, he was out waiting for the young inventor. But this time it was not the case.

"Is Mr. Damon in?" Tom asked of the maid who answered his ring.

"Yes, Mr. Swift. You'll find him in the library," and she ushered him in.

"Oh, hello, Tom," greeted Mr. Damon, but the tone was so listless, and his friend's manner so gloomy that the young inventor was quite embarrassed.

"Have a chair," went on Mr. Damon. "I'll talk to you in a minute, Tom. I've got to finish this letter, and it's a hard one to write, let me tell you."

Now Tom was more astonished than ever. Not once had Mr. Damon "blessed," anything, and when this did not happen Tom was sure something was wrong. He waited until his friend had sealed the letter, and turned to him with a sigh. Then Tom said boldly:

"Mr. Damon, is it true that you're having hard luck--in money matters?"

"Why, yes, Tom, I'm afraid I am," was the quick answer. "But who told you?"

"Grant Halling. He was over to get me to fix his airship," and Tom briefly related what had happened.

"Oh, yes, I did mention the matter to him," went on Mr. Damon, and his tone was still listless. "So he told you; did he? Well, matters aren't any better, Tom. In fact, they're worse. I just had to write to a man who was asking for help, and I had to refuse him, though he needs it very much. The truth is I hadn't the money. Tom, I'm afraid I'm going to be a very poor man soon."

"Impossible, Mr. Damon! Why, I thought your investments--"

"I've made some bad ones of late, Tom. I've been pretty foolish, I'm afraid. I drew out some money I had in government bonds, and invested in certain stocks sold by a Mr. Shallock Peters."

"Shallock Peters!" cried Tom, almost jumping out of his chair. "Why, I know him--I mean I've met him."

"Have you, Tom? Well, then, all I've got to say is to steer clear of him, my boy. Don't have anything to do with him," and, with something of a return of his usual energy Mr. Damon banged his fist down on his desk. "Give him a wide berth, Tom, and if you see him coming, turn your back. He'd talk a miser into giving him his last cent. Keep away from Shallock Peters, Tom. Bless my necktie, he's a scoundrel, that's what he is!" and again Mr. Damon banged his desk forcibly.
