a roar if I snitched on you for that thirty thousand. It makes me
scared to think of it."

And from the fact that Tim thus openly mentioned the matter, Young
Dick concluded that there was no possibility of the policeman's son
betraying him.

Not until six weeks afterward, in Arizona, did Young Dick bring up the
subject.

"You see, Tim," he said, "I've got slathers of money. It's growing all
the time, and I ain't spending a cent of it, not so as you can
notice... though that Mrs. Summerstone is getting a cold eighteen
hundred a year out of me, with board and carriages thrown in, while
you an' I are glad to get the leavings of firemen's pails in the
round-houses. Just the same, my money's growing. What's ten per cent,
on twenty dollars?"

Tim Hagan stared at the shimmering heat-waves of the desert and tried
to solve the problem.

"What's one-tenth of twenty million?" Young Dick demanded irritably.

"Huh!--two million, of course."

"Well, five per cent's half of ten per cent. What does twenty million
earn at five per cent, for one year?"

Tim hesitated.
