"You see the chap as made it did not do it for other people, but so that
he could find his way back by it. This line that runs along the bottom
of the other map I take to be the Gila, which is a big river which runs
right through the Indian country, and falls into the Rio Grande. I have
gone up it from that side two or three hundred miles. We were a strong
party, but we had to fight our way back again, and lost pretty near half
our number. You see by the map it lies on the north side of the Gila.
But as the Gila is eight or nine hundred miles long, that don't help us
a great deal, and the map wouldn't be any good to us if it was not for
this mark here up near the top. You see all these things are meant for
mountains, but as one mountain on a map is just like another, we should
be downright done if it was not for this mark. Do you see there are
three little jags here close together? Now I take it those three jags
are meant for a mountain the Indians call the Three Sisters, which is a
mountain with three peaks close together. I never saw it myself, but I
have spoken with miners who have seen it from the north. Now, here you
see, to the south of the Three Sisters, is a cross, and I take it that's
the mine. You see there is a black line waving about among the mountains
that stops at that point. I guess that is the line they traveled by."

"But there is nothing to tell us what scale the map is on, Dave," Tom
said; "it may mean five hundred miles from end to end, it may mean
fifty. If it is five hundred it must be seventy or eighty miles from
those peaks to the cross, if it is fifty it is only seven or eight."

"That is so," Dave agreed.

"Have you any idea how far it is from the three peaks to the river?"
