"You're not," said Mr. Damon, promptly.

"What's that?" ejaculated the man.

"You only think you are coming up here. But you are not. Bless my fortune telling cards!" ejaculated Mr. Damon, "I should say not."

At this point the black-mustached man began to splutter words and threats so fast that nobody could quite understand him. Mr. Damon, however, did not shrink in the least. He stood adamant in the doorway of the cab.

Finding little relief in bad language, the enemy made another attempt to climb up. For one thing, he was physically brave. He did not call on his companions to go where he feared to.

"I'll show you!" he bawled, and scrambled up the rungs of the ladder.

Mr. Damon did show him. He drew from some pocket a black object with a bulb and a long barrel. Somebody below on the cinder path shouted:

"Look out, boss he's got a gun!"

At that moment the marauder reached out to seize Mr. Damon's coat. Then the object in Mr. Damon's hand spat a fine spray into the florid face of the enemy!

"Whoo! Achoo! By gosh!" bawled the big man, and he fell back screaming other ejaculations.
