shops about it, for their work at times required much machinery.

Mrs. Baggert was the housekeeper who looked after Tom and his
father, and got their meals, when they consented to take enough
time from their inventive work to eat. Another member of the
household was Eradicate Sampson, a genial old colored man, who
said he was named Eradicate because he used to eradicate the dirt
about the place.

Koku, just referred to by Tom, was an immense man, a veritable
giant, whom Tom had brought back with him from one of his trips,
after escaping from captivity. The young inventor really brought
two giants, brothers they were, but one had gone to a museum, and
the other took service with our hero, making himself very useful
when it came to lifting heavy machinery.

Tom had a close friend in Ned Newton, who was employed in the
Shopton bank. Another friend was Miss Mary Nestor, a young lady
whose life Tom had once saved. He had many other friends, and some
enemies, whom you will meet from time to time in this story.

After Tom had had many adventures on his motor cycle he acquired a
motor boat, and in that he and Ned went through some strenuous
times on Lake Carlopa, near Tom's home. Then followed an airship,
for Tom got that craze, and in the book concerning that machine I
related some of the things that happened to him. He had even more
wonderful adventures in his submarine, and with his electric
runabout our hero was instrumental in saving a bank from ruin by
making a trip in the speediest car on the road.
