Drilling through the steel doors of a safe is not an easy task, and it is not done quickly, although expert burglars carry tools these days which will cut anything.

And here again it seemed that Handsome was determined to try Nick out to the last, for he bent forward and whispered in his ear:

"Prove one thing more, Dago, and you're made."

"Want me to do the blowing?" asked Nick.

"All right," said Nick. "Light out, then."

"But——"

"Get out, I say. If I do the blowing I'm boss for the time being. Git!"

They did; and again, with the implements and the explosives at hand, Nick went to work; and, as before he worked rapidly and well—as if he were an experienced hand at that sort of employment.
