Thanks. I'm going to keep looking. You are correct, in my understanding of what Grimble says he omitted, at least regarding the chapters themselves. I compared the first river chapter of the first volume between the first and third editions and the text was the same. The illustrations of country houses, fishers, beats, pools, and other "highlights" from the rivers aren't in the consolidation, nor are the introductory comments, and I'm not sure how he handled the fourth map, as there was one in each of the original volumes, but only three in the consolidation. These are little things to leave out, and I can understand his reason for doing so -- to conserve space -- but they enrich the originals immensely. He could have also formatted the originals singled spaced and fully justified, instead of half page and double spaced, and included the illustrations. That would have condensed them enough for one volume, I think.
