Margaret was put into the charge of her faithful house-keeper, and Roland did not see her again until the evening. As she met him she began immediately to talk upon some unimportant subject, and there was that in her face which told him that it was her desire that the great thought which filled both their minds should not be the subject of their conversation. She told him she was going to the sea-shore for a short time; she needed a change, and she would go the next day. He understood her perfectly, and they discussed various matters of business connected with the Works. She said nothing about the time of her return, and he did not allude to it. On the day that Margaret left Sardis, Roland began his preparations for descending the shaft. He had so thoroughly considered the machinery and appliances necessary for the undertaking, and had worked out all his plans in such detail, in his mind and upon paper, that he knew exactly what he wanted to do. His orders for the great length of chain exhausted the stock of several manufactories, and the engines he obtained were even more powerful than he had intended them to be; but these he could procure immediately, and for smaller ones he would have been obliged to wait. The circular car which was intended to move up and down the shaft, and the peculiar machinery connected with it, with the hoisting apparatus, were all made in his Works. His skilled artisans labored steadily day and night. It was ten days before he was ready to make his descent. Margaret was still at the sea-shore. They had written to each other frequently, but neither had made mention of the great shaft. Even when he was ready to go down he said nothing to any one of any immediate intention of descending. There was a massive door which covered the mouth of the pit; this he ordered locked and went away. The next morning he walked into the building a little earlier than was his custom, called for the engineers, and for Mr. Bryce, who was to take charge of everything connected with the descent, and announced that he was going down as soon as preparations could be made. Mr. Bryce and the men who were to assist him were very serious. They said nothing that was not necessary. If their employer had been any other man than Roland Clewe it is possible they might have remonstrated with him. But they knew him, and they said and did nothing more than was their duty.
