Here is a portion of Chapter VI, "In Which Pooh Invents a New Game and Eeyore Joins In," from The House At Pooh Corner, and my photos to illustrate.
"There was a broad track, almost as broad as a road, leading from the Outland to the Forest, but before it could come to the forest it had to cross this river.
So, where it crossed, there was a wooden bridge, almost as broad as a road, with wooden rails on each side of it. Christopher Robin could just get his chin to the top rail, if he wanted to, but it was more fun to stand on the bottom rail, so that he could lean right over, and watch the river slipping slowly away beneath him. Pooh could get his chin on the bottom rail if he wanted to, but it was more fun to lie down and get his head under it, and watch the river slipping slowly away beneath him. And this was the only way in which Piglet and Roo could watch the river at all, because they were too small to reach the bottom rail. So they would lie down and watch it...and it slipped away very slowly, being in no hurry to get there."
