What it means is that if the farmers wash the sheep in May the wool is not so strong and healthy as it is later, and comes off in the water. While, if they wash them in June the wool is quite crisp and stands on end, and so is very easy to cut. Usually the farmers wash the sheep in the beginning of June, and these two children always manage to find out the day before. They come and bang at my door as usual, but when they come in they bring my hat and walking-stick with them, for they know quite well that on sheep-washing day I am sure to want to come with them. And then off we go along the road that leads by the hawthorn tree, over the moor and down on the other side, to where a little river runs between two farms about a mile from each. The river widens into a broad shallow pool, and here the farmers bring the sheep. The Imp and the Elf and I have a fine seat in the boughs of a big oak that overhangs the water. Here we sit in a row and have a splendid view. The sheep are all crowded together in pens at each side of the water, and the farmers wade out into the stream taking the sheep between their legs, and wash them one after the other. I told you there were two farms who use this washing place. Well, every year they race in their sheep-washing, and see who can get most sheep washed in the shortest time. The Elf takes one side and the Imp takes the other, and it is really quite exciting. When the sheep are all clean they are turned loose in the fields again for a whole week in which to get properly dry. Then they are driven into the farmyards or into pens in the fields, and the farmers clip the wool off them close to the skin. They only shear the old sheep and last year's lambs; and that is why, after shearing time, the new lambs have so much finer and longer coats than those of their mothers. We always wondered why that was, until we found out that the farmers only clip the tails of the lambs, but leave their coats on, while they take all the wool off the old sheep, and send it away to be made into nightgowns and things for Imps and Elves and you and me and everybody else.
