Pattie had made a careful calculation. A penny each to be admitted to the fair, a penny each for a turn on the merry-go-round; a penny each for a visit to the fat lady; a penny each for a peep at the man with two heads. All this fun, this intoxicating delight, could be obtained for eightpence. There would still be fourpence over. Pattie explained to Harriet as they were approaching the fair how she meant to spend her money. Harriet nodded. Pattie's programme was carried out to perfection. How delightful it was! Oh, the fascination of that rush through the air on those prancing horses! And oh--the mystery of looking at the fat woman, and the thrill which went through them when they gazed at the man with two heads! But the delight was short, and quickly over. They had not been half an hour at the fair, but the whole of their programme had been carried through, and eight pence out of Pattie's twelve had vanished. Still, there were four more to spend. They might have two more turns each on the merry-go-round, or they might buy some gingerbread at the gingerbread stall. That stall was a most fascinating one, for the gingerbread was made into all kinds of funny shapes. There were gingerbread dogs, gingerbread cats, gingerbread birds; and there were also horses of gingerbread, and elephants of gingerbread, and--what was more exciting than anything else--the wonderful and handsome lady who sold the gingerbread cakes could write anything to order on them. She had a sort of pencil which she dipped in liquid sugar, and behold, Pattie's name could appear on the cake, or Harriet's name, or any other thing that the girls happened to ask for. Should they have a gingerbread each? Oh yes, they must. Harriet decided that she would have written on her gingerbread cat, "Harriet-- the Queen of Hearts." She could get all this for a penny. She borrowed a penny from Pattie, and the deed was done. She would not eat her treasure on any account--she would carry it home with her. By and by, she might show it to the children in the old house in the country, and describe to them how she of all others on that special morning had won the heart of a little boy. She was in ecstasies over her treasure. Pattie also secured a gingerbread cake with a suitable inscription. But now there were only two pennies left. They might have one more ride on the merry-go-round, and then they would go home. Had they done this, that which happened would not have happened, for they would have found little Ralph asleep on the sofa, and Harriet would have rushed back to the school with him before Miss Ford had time to miss either of them. But, just as they were about to leave the fair, who should come up and speak to Pattie, but her father's chemist, for Dr Pyke kept his own dispensary.
