e was developing his
electric runabout and rifle, but of late he had not spent much time in
it.

"Somebody's in there!" reflected the young inventor, as he heard yells
coming from the open door of the place. "And if it isn't Koku and
Eradicate I miss my guess! Wonder what they can be doing there."

He crossed the yard between his private office and the electrical shop
in a few rapid strides, and, as he entered the latter place, he was
greeted with a series of wild yells.

"Good volume of sound here, at all events," mused Tom. "Almost as much
as my motor made when I was trying to talk to Mary. Hello there! What's
going on? Is any one hurt? What's the matter?" he cried, for, at first,
he could see no one in the dim light of the place. The interior was a
maze of electrical apparatus.

"Who's here?" demanded Tom, as he advanced.

"Oh, Master! Come quick! Koku 'most dead an' no can let go!" was the
cry.

"Yo' jest bet yo' cain't let go!" chimed in the voice of Eradicate. "I
done knowed yo would git into trouble ef yo' come heah, an' I'se glad
ob it! So I is!"

"What is it, Rad? What has happened to Koku?" cried Tom, running
forward, for though no very powerful current could be turned on in the
electrical shop at this period of unuse, there was enough to be very
painful. "What is it, Rad?"

"Oh, dat big foolish giant, Koku, done got his se'f into trouble!"
chuckled the colored man. "He done got holt ob one ob dem air
contraptions, Massa Tom, an' he cain't let go! Ha! Ha! Golly! Look at
him squirm!" and Rad laughed shrilly, which accounted for some of the
sounds Tom had heard.

Then came yells of rage and pain from the giant, and they were so loud
and vigorous, mingling with Eradicate's as they did, that it was no
wonder Tom was startled. The sounds were heard in the other shops, and
men came running out. But before then Tom had put an end to the trouble.

One look showed him what had happened. Just how or why Koku and
Eradicate had entered the electrical shop Tom did not then stop to
inquire. But he saw that the giant had grasped the handles of one of
the electric machines, designed for charging Leyden jars used in Tom's
experiments, and the powerful, though not dangerous, current had so
paralyzed, temporarily, the muscles of the giant's hands and arms that
he could not let go, and there he was, squirming, and not knowing how
to turn off the current, and unable to ease himself, while Eradicate
stood and laughed
