He was never under any pretense, or in any way, to strike her with clay, or with anything made or baked from clay. Any blow with that from which men made pots and pans, and jars and dishes, or in fact, with earth of any sort, would mean the instant loss of his wife. Even if children were born in their home, the mother would leave them, and return to fairy land under the lake, and be forever subject to the law of the fairies, as before her marriage.
The farmer was very much in love with his pretty prize, and as promises are easily made, he took oath that no clay should ever touch her.
They were married and lived very happily together. Years passed and the man was still a good husband and lover. He kept up the habit which he had learned from a sailor friend. Every night, when far from home and out on the sea, he and his mates used to drink this toast; "Sweethearts and wives: may every sweetheart become a wife and every wife remain a sweetheart, and every husband continue a lover."
So he proved that though a husband he was still a lover, by always doing what she asked him and more. When the children were born and grew up, their father told them about their mother's likes and dislikes, her tastes and her wishes, and warned them always to be careful. So it was altogether a very happy family.
One day, the wife and mother said to her husband, that she had a great longing for apples. She would like to taste some like those which he long ago gave her. At once, the good man dropped what he was doing and hurried off to his neighbor, who had first presented him with a trayful of these apples.
The farmer not only got the fruit, but he also determined that he would plant a tree and thus have apples for his wife, whenever she wanted them. So he bought a fine young sapling, to set in his orchard, for the children to play under and to keep his pantry full of the fine red-cheeked fruit. At this his wife was delighted.
So happy enough—in fact, too merry to think of anything else, they, both husband and wife, proceeded to set the sapling in the ground. She held the tree, while he dug down to make the hole deep enough to make sure of its growing.
But farmers are sometimes very superstitious. They even believe in luck, though not in Puck. Some of them have faith in what the almanac, and the patent medicine may say, and in planting potatoes according to the moon, but they scout the idea of there being any fairies.
With the farmer, this had become a fixed state of mind and now it brought him to grief, as we shall see. For though he remembered what his wife liked and disliked, and recalled what her father had told him, he had forgotten that she was a fairy.
With this farmer and other Welsh mortals, it had become a habit, when planting a young tree, to throw the last shovelful of earth over the left shoulder. This was for good luck. The farmer was afraid to break such a good custom, as he thought it to be.
