'I'll think about it,' said Madison, gruffly.

'I will send up some books for them to make an opening,' said Mary. 'I should not like to think of men living in such scenes, without being the better for them.'

Robson was here obliged to call Madison to refer some question to him; but Mary had another talk with him, when he begged to know if there were likely soon to be an opportunity of sending to England. He had some fossils which he wished to send to Lord Fitzjocelyn; and he fetched them, and explained his theories with regard to them as if he had almost forgotten that she was not his young Lord. She carried his request to her father, and was answered that of course he might take a holiday if he could leave the works with safety; he had better spend a few days in the town when he did come. With this answer she made him happy; and they set off, to the extreme joy of Rosita, who had engrossed much less attention than she had expected, and declared she would never have come into these horrible places if she could have imagined what they were like. Certainly, no one wished to have her company there again.

When Mr. Ponsonby mentioned the permission which he had accorded to Madison, Robson coughed and looked annoyed. Mary could not help suspecting that this was because the request had not been preferred through himself. 'So the young fellow wants to be coming down, does he? I thought his ardour was too hot to last long.'

'Very natural that the poor lad should want a holiday,' said Mr. Ponsonby. 'It must take a tolerable flow of spirits to stand long, being so many feet above the level of the sea, in caves fit for a robber's den at the theatre.'

'Oh, I am making no objection, sir,' returned Robson; 'the young man may take his pleasure for what I care, so he can be trusted not to neglect his business.'

Here the path narrowed, and Mary had to fall back out of hearing; but she had an unpleasant suspicion that Robson was telling her father something to Tom's disadvantage, and she had to consider how to avoid rousing a jealousy, which she knew might be dangerous.

Mr. Ward, however, came up to interrupt her thoughts and watch the steps of her mule. The worst difficulties of the descent had precluded all conversation; and the party were just beginning to breathe freely, think of terra firma as not far off, and gaze with easier minds on the marvellous ocean. Mary went on in very comfortable discussion of the wonders they had seen, and of Madison's remark that the performances of the Incas made one quite ashamed of the achievements of modern science—a saying in which Mr. Ward perfectly agreed; and then he began to say something rather long, and a little disconnected, and Mary's mind took an excursion to Aunt Kitty, and the reading of the letter that she was going to write, when suddenly something in Mr. Ward's voice startled her, and recalling her attention, she discovered, to her dismay, that he was actually making her an offer! An offer! She would as soon have expected one from her father! And oh! how well expressed—how entirely what it ought to be! How unlike every one of those three of her past experience!

In great distress she exclaimed, 'Oh, Mr. Ward, pray do not—indeed, I cannot!'

'I feared that I was but too likely to meet with such an answer,' said Mr. Ward; 'and yet your father encouraged me to hope, that in course of time—'
