'Oh, I know what you are going to say,' cried Donald.

'And I second the motion,' said Sandie Donaldson.

'Well,' I exclaimed, 'seeing, Sandie, that no motion has yet been made—'

'Here is the motion, then,' exclaimed Dugald, jumping out of his saddle.

It was a motion we all followed at once; and as the day was getting near its close, the Gauchos set about looking for a bit of camping-ground at once. As far as comfort was concerned, this might have been chosen almost anywhere, but we wanted to be near to water. Now here was the mystery: the glen was not three miles long altogether, and nowhere more than a mile broad; all along the bottom it was tolerably level and extremely well wooded with quite a variety of different trees, among which pines, elms, chestnuts, and stunted oak-trees were most abundant; each side of the glen was bounded by rising hills or braes covered with algorroba bushes and patches of charmingly-coloured cacti, with many sorts of prickly shrubs, the very names of which we could not tell. Curious to say, there was very little undergrowth; and, although the trees were close enough in some places to form a jungle, the grass was green beneath. But at first we could find no water. Leaving the others to rest by the edge of the miniature forest, Dugald and I and Archie set out to explore, and had not gone more than a hundred yards when we came 201 to a little lake. We bent down and tasted the water; it was pure and sweet and cool.

'What a glorious find!' said Dugald. 'Why, this place altogether was surely made for us.'

We hurried back to tell the news, and the horses and mules were led to the lake, which was little more than half an acre in extent. But not satisfied with drinking, most of the dogs plunged in; and horses and mules followed suit.

'Come,' cried Donald, 'that is a sort of motion I will willingly second.' He commenced to undress as he spoke. So did we all, and such splashing and dashing, and laughing and shouting, the birds and beasts in this romantic dale had surely never witnessed before.

Dugald was an excellent swimmer, and as bold and headstrong in the water as on the land. He had left us and set out to cross the lake. Suddenly we saw him throw up his arms and shout for help, and we—Donald and I—at once commenced swimming to his assistance. He appeared, however, in no danger of sinking, and, to our surprise, although heading our way all the time, he was borne away from us one minute and brought near us next.

When close enough a thrill of horror went through me to hear poor Dugald cry in a feeble, pleading voice,
