The chemist was a young man of the name of Frost, very much addicted to eating gingerbreads and amusing himself at fairs. He was delighted to see Pattie; and Pattie, with some pride, introduced Harriet to him. Mr Frost was a fat, podgy young man, and he felt quite pleased to walk with the little girls. With one on his right hand and one on his left he perambulated round and round the fair with them now. "What have you seen?" he asked, and when they explained, he told them that they had practically seen nothing at all, and that now it would be his pleasure to give them a good time. He described what he meant to do, and certainly his programme was delightful. He himself would go on the merry-go-round with a little girl on each side of him, and they would fly right round not once, but several times; and afterwards, they would go into a little theatre and witness a wonderful piece of acting in which there was a giant and a pigmy, and some acting dogs, and an elephant and even a lion. The entertainment was of a jumble order, but it would be intensely exciting. It would take, Mr Frost said, no time at all. They must not miss it, however, for it really was first-rate, of that he could assure them. Before Harriet could even reply, he had provided tickets for all three-- tickets which cost sixpence each. He really was a most generous young man. "But," said Harriet, turning to Pattie, "won't this make me dreadfully late?" "Late?" cried Mr Frost, overhearing her. "Not a bit of it. I tell you it will be over in no time at all. Here, take a hand each, girls, and we'll squeeze well to the front. We mustn't miss the beginning of the fun. The fat lady comes on first of all with the kangaroo; oh, it will be screamingly funny!" The next minute, they were inside the tent where the great performance was to take place. They were inside with a crush of people behind them, and Harriet forgot everything else. The entertainment was of the breathless order; before you had time to recover from one astounding surprise, another still more astounding followed on its heels. The fat lady's performance was nothing at all to that done by the man with two heads--he really managed these double appendages with the greatest cleverness, nodding and winking simultaneously with both, and causing the people to shriek, holding their sides with mirth. "He hasn't two heads at all, you know," said Mr Frost, "but it's wonderfully cleverly managed for all that." Harriet and Pattie were almost sorry. They would much rather have believed that the man was possessed of the double head. "Oh!" said Pattie, with a gasp. "I was thinking what a lot he could do if they were really two heads." Mr Frost roared with laughter.
