"We'd better notify Police Headquarters."

"I have. They gave me the laugh. Told me it was a pipe-dream. They're sore on us because of our attack on the department for dodging saloon law enforcement."

"I don't like this, Mac," said Hal. "What a fool I was to put the press in the most exposed place."

"Fortify it."

"With what?"

"The rolls."

Print-paper comes from the pulp-mills in huge cylinders, seven feet long by four in diameter. The highest-powered small arm could not send a bullet through the close-wrapped fabric. Ellis's plan offered perfect protection if there was enough material to build the fortification. The entire pressroom force was at once set to work, and in half an hour the delicate and costly mechanism was protected behind an impenetrable barrier which shut it off from view except at the south end. The supply of rolls had fallen a little short.

"Let 'em smash the window if they like," said Ellis. "Plate-glass insurance covers that. I wish we had something for that corner."

"With a couple of revolvers we could guard it from these windows," said Hal. "But where are we to get revolvers on a Sunday night?"

"Leave that to me," said Ellis, and went out.
