Another startling moment is when the man turns back the grimy wool from the sheeps' shoulders and they look suddenly like ladies in the stalls of a theatre. The sheep are so frightened by the shearing that it makes them quite white and thin, and as soon as they are set free they begin to nibble the grass at once, quite anxiously, as if they feared that they would never be worth eating. David wonders whether they know each other, now that they are so different, and if it makes them fight with the wrong ones. They are great fighters, and thus so unlike country sheep that every year they give Porthos a shock. He can make a field of country sheep fly by merely announcing his approach, but these town sheep come toward him with no promise of gentle entertainment, and then a light from last year breaks upon Porthos. He cannot with dignity retreat, but he stops and looks about him as if lost in admiration of the scenery, and presently he strolls away with a fine indifference and a glint at me from the corner of his eye.
The Serpentine begins near here. It is a lovely lake, and there is a drowned forest at the bottom of it. If you peer over the edge you can see the trees all growing upside down, and they say that at night there are also drowned stars in it. If so, Peter Pan sees them when he is sailing across the lake in the Thrush's Nest. A small part only of the Serpentine is in the Gardens, for soon it passes beneath a bridge to far away where the island is on which all the birds are born that become baby boys and girls. No one who is human, except Peter Pan (and he is only half human), can land on the island, but you may write what you want (boy or girl, dark or fair) on a piece of paper, and then twist it into the shape of a boat and slip it into the water, and it reaches Peter Pan's island after dark.
We are on the way home now, though, of course, it is all pretence that we can go to so many of the places in one day. I should have had to be carrying David long ago and resting on every seat like old Mr. Salford. That was what we called him, because he always talked to us of a lovely place called Salford where he had been born. He was a crab-apple of an old gentleman who wandered all day in the Gardens from seat to seat trying to fall in with somebody who was acquainted with the town of Salford, and when we had known him for a year or more we actually did meet another aged solitary who had once spent Saturday to Monday in Salford. He was meek and timid and carried his address inside his hat, and whatever part of London he was in search of he always went to the General Post-office first as a starting-point. Him we carried in triumph to our other friend, with the story of that Saturday to Monday, and never shall I forget the gloating joy with which Mr. Salford leapt at him. They have been cronies ever since, and I notice that Mr. Salford, who naturally does most of the talking, keeps tight grip of the other old man's coat.
The two last places before you come to our gate are the Dog's Cemetery and the chaffinch's nest, but we pretend not to know what the Dog's Cemetery is, as Porthos is always with us. The nest is very sad. It is quite white, and the way we found it was wonderful. We were having another look among the bushes for David's lost worsted ball, and instead of the ball we found a lovely nest made of the worsted, and containing four eggs, with scratches on them very like David's handwriting, so we think they must have been the mother's love-letters to the little ones inside. Every day we were in the Gardens we paid a call at the nest, taking care that no cruel boy should see us, and we dropped crumbs, and soon the bird knew us as friends, and sat in the nest looking at us kindly with her shoulders hunched up. But one day when we went, there were only two eggs in the nest, and the next time there were none. The saddest part of it was that the poor little chaffinch fluttered about the bushes, looking so reproachfully at us that we knew she thought we had done it, and though David tried to explain to her, it was so long since he had spoken the bird language that I fear she did not understand.
