Meanwhile Silas stubbornly held to his point that he thought he was throwing the weeds on the rubbish heap, and that he had not heard Isobel coming past.

"Well, Isobel," said Pamela, "it won't do any good to prolong this argument—and time's flying past. Let's hurry in and see what we can do to the dress—or you must wear one of mine. And, Beryl, will you explain to Tom Bagg and ask him in to wait for twenty minutes—we mustn't be longer than that." Then she turned to Silas. "I think," she said, "that at any rate you might apologize——"

"Apologize! What good will that do! I don't want an apology from him," cried Isobel. "I'm too disgusted with him—besides, I know he did it purposely. He's just telling lies, because he is frightened now at what he's done.... But if the dress is ruined beyond repair he shall pay for it—I don't care what he says.... I'll make him pay, if—if I have to go to law about it." And without waiting for anything further Isobel turned on her heel and marched away into the house, followed by Pamela, who was secretly longing to laugh at old Silas's expression and Isobel's theatrical outburst. In a few moments the group round Silas dispersed.

Silas stood for a while scratching the top of his head and looking at the ground where Isobel had stood, then he picked up his spade and resumed his digging.

Presently he began to chuckle. "I said I'd learn 'er," he told himself. "An' I did learn 'er. Nice and slimy and wet them weeds were—an', after all, I did only throw 'em on a rubbidge 'eap. That's what she is."

Why old Silas had not taken his revenge on Isobel before this it is impossible to say. He had not thought out any clear plan for a long time, but had waited for an idea, and when he had got one he had turned it over in his mind with relish for some time, and then begun to look around for an opportunity—and, at length, to-day he had found one.

While Tom Bagg waited in the hall, and Caroline wandered about asking if she could be of any use, Pamela and Beryl, finding that Isobel's dress could not be remedied unless it was thoroughly washed and ironed, quickly got out a white muslin frock of Pamela's and set to work to make it fit Isobel. Pamela was more Isobel's build than either of the other two girls, and so her dress was not such a bad fit, and with the aid of a needle and cotton, and some safety pins and a pair of scissors, it soon began to look presentable on Isobel. Of course it did not look as pretty on Isobel as her own white silk had done—but it was fortunate that Pamela had even a white muslin frock ready to lend Isobel in this emergency. Martha and Ellen lent a hand, hurrying to and fro, looking for pins and scissors, and helping Isobel to brush the soil out of her hair and re-do it. For although they all knew that Isobel's conduct toward old Silas had been very rude and trying, to say the least of it, yet they all felt sorry for her that he had chosen just this occasion to punish her for her treatment of him so many months ago.

There was no time to talk much—they all worked hard, and within half an hour Isobel and Caroline were safely packed away inside Tom Bagg's cab and were jogging briskly along the road to Inchmoor.

Of course Pamela, Beryl, Martha, and Ellen had missed the seven o'clock train, and when they arrived at the Dancing Academy, and were shown into the big dancing-hall, a great number of people were already assembled, and the first part of the programme had begun. Madame, who had received all her guests in the doorway and had shaken hands with each one, had now disappeared behind the door at the back of the raised platform at the end of the hall. The four late arrivals managed to squeeze through the crowd that filled the lower half of the hall, and at length found seats where they could obtain a good view of the evening's proceedings.

A glance round the hall conveyed the impression that Madame's receptions must be very popular affairs; there was scarcely a vacant seat to be seen. Most of the audience were relatives of the pupils or friends, or prospective pupils, but there were a number of people who were outsiders—people who had received a pressing and urgent invitation from Madame at the last minute; for always before her receptions Madame would be suddenly seized with an unreasonable fear that the hall would be empty of onlookers, or only half filled, and so she would send out a score or so of these pressing and flattering invitations at random, and in a frantic hurry, a couple of days before the reception took place. And generally a few of these last-minute visitors would turn up.
