"Mr. Hildreth gave the pig to Sarah," she explained. "It is all hers. And you mustn't tell anyone about buying it--that is, that the money is for Louisa." Mr. Robinson looked perplexed, as well he might. "But little grasshoppers!" he ejaculated, scratching his head. "You can go just so far with a secret, you know; if I buy this Gay farm a heap of people will have to know about it." "Oh, who?" said Rosemary in quick distress. "Well, the guardian, or whoever holds the estate for them," said Mr. Robinson. "Then the lawyer who draws the deed and all the folks at the Court House who have anything to do with the searches and like that." "I don't understand," declared Rosemary, while Sarah and Shirley began to fold up the dresses Bony had worn. "But I am sure there is no guardian. Louisa would have said something about it." "Never mind," said the circus agent kindly. "Plenty of time to find out all that later. Now if the little girl really wants to sell the pig--" He named a figure that surprised them all. Whether, as Doctor Hugh suspected when he heard the story, Mr. Robinson wanted to help the Gays too, and added more as a practical way to assist them; or whether, as Sarah was firmly convinced, Bony was the smartest pig he had ever seen and he recognized his value, does not really matter. There, before three pairs of wondering eyes, he counted out a little heap of soiled bills and gave them to Sarah. "I'll take the pig in the morning," he said, folding up the remainder of his money and fastening the roll with an elastic. "I expect to put up with the Hildreths to-night and one of the boys will take me back to town after breakfast. You look after the pig for me till then, won't you?" Sarah promised and then, as she did not seem to know what to do with the money, he suggested that she run into the house and give it to her mother to put away. The three girls were anxious to go over to the Gay farm with Mr. Robinson, but he explained that he thought he could talk better to Alec and Louisa alone. "I'm just going to wander over there and tell 'em that Richard Gilbert sent me," he said. "I'll say he heard I wanted to buy a small place and that I thought they might be in the market. I'll tell you all about it, soon as I get back." They watched him start "across lots" to the Gay farm and then Sarah went into the house to ask her mother to put away the money. "You've sold Bony, dear?" echoed Mrs. Willis when she heard the news. "And for all this money? Who bought him, Sarah? When did you sell your pig?" Sarah told her about Mr. Robinson, and Rosemary and Shirley listened eagerly for they had not heard the details, nor learned how Sarah had met the circus agent. "I always said Bony was a smart pig!" wound up Sarah, watching her mother counting the money into a little black tin box, fitted with a lock and key.
