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.
