One of these men was Clarence King on his way up to the camp. Adams fell into his arms. As with most friendships, it was never a matter of growth or doubt. Friends are born in archaic horizons; they were shaped with the Pteraspis in Siluria; they have nothing to do with the accident of space. King had come up that day from Greeley in a light four-wheeled buggy, over a trail hardly fit for a commissariat mule, as Adams had reason to know since he went back in the buggy. In the cabin, luxury provided a room and one bed for guests. They shared the room and the bed, and talked till far towards dawn.
