Both Ned and the Captain sprang after the lads, the latter expressing in very vigorous language his opinion of boys who would take such risks out of curiosity.

"I'd rather wait an hour for an explosion than go up to see why it didn't come off in time," he said. "That Jimmie needs a good beating. He'll get it, too, if he doesn't behave!"

Ned laughed, serious as the situation was, at the thought of what would be apt to happen if the Captain should lay hands on the little fellow in anger. He would have the other boys on his hands in a second!

When Ned rounded the corner he saw Jimmie's heels half blocking a cellar window. Thick smoke was oozing out around him, and Frank and Jack were trying to pull him back.

"You let go!" they heard the little fellow shout. "I guess I know what
I'm doin'. You let go!"

"Wait!" Ned said, then he stooped over and called out to Jimmie:

"Is the fuse out?"

"Sure!" was the reply. "'Sure the fuse is out, but before it went out it set fire to something on the cellar bottom, an' the blaze is workin' its way up to the powder, or whatever it is. Ouch!" he added, as Jack gave a pull at his foot. "You let go!"

"Let him go," Ned advised. "Perhaps he can get in there in time to prevent the explosion."

"The little gink!" Jack exclaimed, "I wanted to see the thing bust up.
Now he's spoiled it!"
