as Jim went overboard on one side and I on the other, she come smashing straight through the raft. I dived--and I aimed to find the bottom, too, for a thirty-foot wheel had got to go over me, and I wanted it to have plenty of room.  I could always stay under water a minute; this time I reckon I stayed under a minute and a half.  Then I bounced for the top in a hurry, for I was nearly busting.  I popped out to my armpits and blowed the water out of my nose, and puffed a bit.  Of course there was a booming current; and of course that boat started her engines again ten seconds after she stopped them, for they never cared much for raftsmen; so now she was churning along up the river, out of sight in the thick weather, though I could hear her. I sung out for Jim about a dozen times, but I didn't get any answer; so I grabbed a plank that touched me while I was “treading water,” and struck out for shore, shoving it ahead of me.  But I made out to see that the drift of the current was towards the left-hand shore, which meant that I was in a crossing; so I changed off and went that way.
