Captain Johnson with his steamboat had been to the head of navigation.

Ives and Johnson must now pass each other before the end of this month of December, and the meeting of the two steamers took place somewhere in this Colorado Valley, for, under date of January 31st, Ives says: "Lieutenant Tipton took advantage of an opportunity afforded a few days ago, by our meeting Captain Johnson, with Lieutenant White and party returning to the fort, and went back with them in order to bring up the pack-train." He does not mention, however, that Johnson was piloting a steamboat larger than the Explorer.

Indeed, I have been told that he failed to reply to Johnson's salute.

Slowly they worked their way up, and on up, toward their final goal, though the water was exceptionally low.

At last reaching Bill Williams Fork, Ives, who had seen it at the time he was with Whipple about four years earlier, could not at first find it, though, on the former occasion, in the same season, it had been a stream thirty feet wide.
