to Cuivaca fer the pay tomorrow. Next day's pay day. I don't like
to send this here bum, I can't trust a greaser no better, an' I can't
spare none of my white men thet I ken trust."

"Send him with a couple of the most trustworthy Mexicans you have,"
suggested the boss.

"There ain't no sich critter," replied Grayson; "but I guess that's the
best I ken do. I'll send him along with Tony an' Benito--they hate
each other too much to frame up anything together, an' they both hate a

"But they'll get back with the money, eh?" queried the boss.

"If Pesita don't get 'em," replied Grayson.

CHAPTER X. BILLY CRACKS A SAFE

BILLY BYRNE, captain, rode into Cuivaca from the south. He had made a
wide detour in order to accomplish this; but under the circumstances he
had thought it wise to do so. In his pocket was a safe conduct from one

Pesita had given him for the purpose of an excuse to examine the lay of
the bank from the inside. Billy took a long time to count the change.
All the time his eyes wandered about the interior while he made mental
notes of such salient features as might prove of moment to him later.
The money counted Billy slowly rolled a cigarette.

He saw that the bank was roughly divided into two sections by a wire and
wood partition. On one side were the customers, on the other the clerks
and a teller. The latter sat behind a small wicket through which he
received deposits and cashed checks. Back of him, against the wall,
stood a large safe of American manufacture. Billy had had business
before with similar safes. A doorway in the rear wall led into the yard
behind the building. It was c
