'Dawn,' Ross said, 'is one of the things you are disposed to admire when you first come to Argentine, but when the hot weather begins you feel inclined to throw your boots at the sun when it rises.'

Now it was afternoon, and a heavy day's work in the corral was over. Peter was writing letters, while Ross and Toffy dozed in long cane chairs in the corridor. Purvis sat on the little cretonne-covered box beside the empty fireplace, and looked with lack-lustre eyes into space. He had been helping with some work on the estancia; but he had brought none of his own men with him, as some neighbours had done, and the ominous whisper grew that there was trouble down at his place. Ross treated the matter lightly, and explained it by saying that Purvis was making a fortune with his steamers, and was feeding his men on carne flacca. 'Purvis does his best, poor beast, and I believe he is worth a dozen detectives in this affair of yours, Peter.'

Peter himself, however, was inclined to draw back a little. 'He has put me on the wrong scent once or twice,' he said.

'After all, you haven't told him much,' said Ross.

And Peter agreed that this was so.

There was an undefined feeling in his mind that if he had to learn that his brother was alive he would like to hear of it through such legalized channels as Sir John Falconer was arranging. The detective spirit was not strong in Peter Ogilvie. He would have preferred to take the whole world into his confidence, and to ask them to speak out if they had anything to say. But Mr. Semple and Sir John had cautioned him against this procedure, and the inquiries he had been able to make had been conducted at one time with such surprising caution that no possible clue was given towards finding the child, while at others he had allowed more to be known than Mr. Semple, for instance, would have thought wise. He had lately become more reserved in his dealings with their neighbour at La Dorada, and began almost to try to discount the fact that he had ever consulted Purvis at all about his affairs. He lightly waved aside any information that was given him, and was always busy at the moment when Purvis wanted a few words with him. He advised Toffy to say, if he were asked, that Sir John Falconer was making inquiries, and that for the present they themselves were not going to move in the matter. Toffy and Ross both thought that they had gone too far to make such an attitude possible. 'What harm can it do to find out what he knows?' Ross said more than once.

But Peter still held back. 'I hate his confounded mysteries,' he said, 'and I don't attach much importance to things that are only known in a back-stairs sort of way.'

This afternoon in his letter to Jane he had given it as his opinion that the little man who they had thought might help them was proving to be rather a fraud. 'He is always starting ideas,' wrote Peter, 'and nothing comes of them. Why, bless me, you would think that Argentine was peopled with unclaimed babies and stiff with missing heirs.'

He felt better when he had unbosomed himself to Jane and had got rid of some of his impatience and ill-temper.

'I think I 'll ride to the post presently,' he said, getting up and stretching himself; 'it must get cooler soon.'
