"I would like to go, Dad," admitted the young inventor, "only I'd never think of it while you weren't well." "Don't worry about me, Tom. Of course I will be lonesome while you are gone, but don't let that stand in the way. If you want to go to Africa, you may start to-morrow, and take your new rifle with you." "The rifle part would be all right, Dad, but if I went I'd want to take an airship along, and it will take me some little time to finish the Black Hawk, as I have named my new craft." "Well, there's no special hurry, is there?" asked Mr. Swift. "The elephants in Africa are likely to stay there for some time. If you want to go, why don't you get right to work on the Black Hawk and make the trip? I'd like to go myself." "I wish you would, Dad," exclaimed Tom eagerly. "No, son, I couldn't think of it. I want to stay here and get well. Then I am going to resume work on my wireless motor. Perhaps I'll have it finished when you come back from Africa with an airship load of elephants' tusks." "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 be 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.
