"I asked dad about Cassey," were his first words, after greetings had been exchanged. "He said he thought very likely the man was the one you had in mind, for this stuttering fellow came from Elwood and his first name was Daniel. It's hardly likely there'd be two men of the same name in that little town."
"Did your father know anything about what kind of fellow he was?" asked Joe.
"Dad said that he had the reputation of being tricky and hard-fisted," answered Herb. "But as far as he knew he hadn't been caught in anything yet that could put him in jail. He went up in the air when I told him about Miss Berwick, and said he'd like to get hold of the fellow and break his neck. He thinks Miss Berwick ought to get a good lawyer and bring the rascal into court. But at the same time he thinks she may have a hard time proving her case, as she hasn't any receipt or any witnesses. She could simply say she'd paid him and he could say she hadn't. All he'd have to do would be to stand pat and put it up to her to prove her case. And how is she going to do it?"
"Do you mean to say that he could get away with a thing as raw as that?" asked Joe, in a white heat.
"He might," declared Bob. "Things just as rank have been pulled off again and again. But at any rate she ought to get after him right away. She's a dead loser as things stand, and if she can only get the rascal in court she may have a chance. Perhaps he hasn't covered his trail as well as he thinks he has, and when a good lawyer gets to questioning him the truth may come out. In any case it's the only way that will give her a ghost of a chance."
The days passed by swiftly until Saturday came and with it the opportunity the boys had looked forward to of going to Dr. Dale's workshop and getting a few practical points on the making of a wireless telephone set.
They found the doctor at a bench that he had rigged up in his barn. On the wall was arranged a large variety of tools and on the bench were strewn several coils of wire and a number of objects the name and use of which the boys did not know.
The doctor, who was in his shirt sleeves, extended a hearty welcome to the boys, who ranged themselves about him, and whose numbers were constantly augmented by newcomers until the barn was well filled.
"What I want to do to-day, boys," he said, "is to show you how easy and simple it is to put up a wireless telephone receiving set without having to spend very much money.
"Now the first thing you have to get and put up is the aerial," he remarked, as he unwound a large coil of copper wire. "You want about a hundred or a hundred and twenty feet of that. You can extend it horizontally for about fifty feet, say, for instance, from the side or back of your house to the barn or the garage, and then have it go up as high as it can go. The upper end doesn't have to be in the outer air, for the sound will come along it if it's in the attic. Still it's better to have it outside if possible. The lower end of the wire has to be connected with the ground in some way, and you can fix that by attaching it to a water pipe or any other pipe that runs into the ground. A good way is to let it down the side of the house and put it through the cellar window and fasten it to a pipe.
