“Perhaps,” admitted the young inventor.  “Well, Dad, I’ll think of it.  But now I’m going after my rifle, and—­”

Tom was interrupted by a ring of the front-door bell, and Mrs. Baggert, the housekeeper, who was almost like a mother to the youth, went to answer it.

“It’s Ned Newton, I guess,” murmured Tom, and, a little later, his chum entered the room.

“Oh, I guess I’m early,” said Ned.  “Haven’t you had supper yet, Tom’”

“Yes, we’re just finished.  Come on out and we’ll try the gun.”

“And practice shooting elephants,” added Mr. Swift with a laugh, as he mentioned to Ned the latest idea of Tom.

“Say!  That would he great!” cried the bank clerk.  “I wish I could go!”

“Come along!” invited Tom cordially.  “We’ll have more fun than we did in the caves of ice,” for Ned had gone on the voyage to Alaska.

The two youths went out to the shed where the rifle gallery had been built.  The new electric weapon was out there, and Eradicate Sampson, the colored man, who was a sort of servant and man-of-all-work about the Swift household, had set up the scarecrow figure at the end of the gallery.

“Now we’ll try some shots,” said Tom, as he took the gun out of the case.  “Just turn on a few more lights, will you, Mr. Jackson,” and the engineer, who was employed by Tom and his father to aid them in their inventive work, did as requested.

The gallery was now brilliantly illuminated, with the reflectors throwing the beams on the big stuffed figure, which, save for a face, looked very much like a human being, standing at the end of the gallery.

“I don’t suppose you want to go down there and hold it, while I shoot at it; do you, Rad?” asked Tom jokingly, as he prepared the electric rifle for use.

“No indeedy, I don’t!” cried Eradicate.  “Yo’-all will hab t’ scuse me, Massa Tom.  I think I’ll be goin’ now.”

“What’s your hurry?” asked Ned, as he saw the colored man hastily preparing to leave the improvised gallery.

“I spects I’d better fro’ down some mo’ straw fo’ a bed fo’ my mule Boomerang!” exclaimed Eradicate, as he hastily slid out of the door, and shut it after him.

“Rad is nervous,” remarked Tom.  “He doesn’t like this gun.  Well, it certainly does great execution.”

“How does it work’” asked Ned, as he looked at the curious gun.  The electric weapon was not unlike an ordinary heavy rifle in appearance save that the barrel was a little longer, and the stock larger in every way.  There were also a number of wheels, levers, gears and gages on the stock.

“It works by electricity,” explained Tom.

“That is, the force comes from a powerful current of stored electricity.”

“Oh, then you have storage batteries in the stock?”

“Not exactly.  There are no batteries, but the current is a sort of wireless kind.  It is stored in a cylinder, just as compressed air or gases are stored, and can be released as I need it.”
