t's quite on a par with most G. S. methods."

"I'm not speaking for the G. S., young man," roared Mr. Camp. "I
speak as a director of the Kansas & Arizona. What is more, I
will have those letters inside of twenty-four hours."

He made an angry exit, and I said to Fred, "I wish you would
stroll about and spy out the proceedings of the enemy's camp. He
may telegraph to Washington, and if there's any chance of the
Postmaster-General revoking his order I must go back to Flagstaff
on No. 4 this afternoon."

"He sha'n't do anything that I don't know about till he goes to
bed," Fred promised. "But how the deuce did he know that you had
those letters?"

That was just what we were all puzzling over, for only the
occupants of No. 218 and myself, so far as I knew, were in a
position to let Mr. Camp hear of that fact.

As Fred made his exit he said, "Don't tell Madge that there is a
new complication, for the dear girl has had worries enough
already."

Miss Cullen not rejoining us, and Lord Ralles presently doing so,
I went to my own car, for he and I were not good furniture for
the same room. Before I had been there long, Fred came rushing
in.

"Camp and Baldwin have been in consultation with a lawyer," he
said, "and now the three have just boarded those cars," pointing
out the window at the branch-line train that was to leave for
Phoenix in two minutes.

"You must go with them," I urged, "and keep us informed as to
what they do, for they evidently are going to set the law on us,
and the G. S. has always owned the Territorial judges, so they'll
stretch a point to oblige them."

"Have I time to fill a bag?"

"Plenty," I assured him, and, going out, I ordered the train held
till I should give the word.

"What does it all mean?" asked Miss Cullen, joining me.

I laughed, and replied, "I'm doing a braver thing even than your
party did; I'm holding up a train all by my lonesome."

"But my brother came dashing in just now and said he was starting
for Phoenix."

"Let her go," I called to the conductor, as Fred jumped aboard;
and the train pulled out.

"I hope there's nothing wrong?" Madge questioned, anxiously.

"Nothing to worry over," I laughed. "Only a little more fun for
our money. By the way, Miss Cullen," I went on, to avoid her
questions, "if you have your letters ready, and will let me have
them at once, I can get them on No. 4, so that they'll go East
to-night."

Miss Cullen blushed as if I had said some
