You'll have to have three full sets of chains and whiffletrees for your
six-horse team, of course. You can't bother with dragging a buckboard
along behind to take 'em back with. Go back to the railroad, take a
second load of water, camp the first night out at your first wagon, and
leave the second load of water farther south, twenty-five miles or so.

"Then go back to the Gila and pack the rest of your plunder in this wagon
of yours, all ready to start the minute you get a telegram from me. Wire
back to me so I'll know when to start. You will have water for your
horses at twenty-five miles and fifty, and enough left to use when you go
back for your next trip. After that we'll have other men to help you.

"When you leave the last wagon, put on all the water your horses can
draw. You'll strike little or no sand after that and we'll need all the
water we can get. With no bad luck, you come out opposite the south end
of your black mountain the third day. Wait there for us. It's three long
days, horseback, from Tucson; we ought to get to your camp that night.

"If we don't come, wait till noon the next day. Then saddle up, take your
pack-saddles and kegs, and drag it for the extreme south end of the
mountains on your west, about twenty miles. That ought to leave enough
water at the wagon for us to camp on if we come later. If you wait for
us, your horses will use it all up.

"When you come to the south end of your Cabeza Prieta Mountain, right
spang on the border, you'll find a cañon there, coming down from the
north, splitting the range. Turn up that cañon, and when it gets so rough
you can't go any farther, keep right on; you'll find some rock tanks full
of water, in a box where the sun can't get 'em. That's all. Got that?"
