The meal over, Don Hermoso excused himself, as there were naturally many matters demanding his earliest attention after his long absence from home; while the Senora had her household affairs to attend to. Carlos therefore took the task of entertaining Jack upon himself, with his sister as chief assistant, and proposed a ride, as there were many charming spots in the neighbourhood that he wished his friend to see. The horses were accordingly ordered, and the three young people, despising the usual afternoon siesta, set off, taking a path which led upward through a wild and most picturesque ravine, down which a mountain stream brawled and foamed, the murmurous tumult of its waters mingling musically with the sough of the wind in the multitudinous trees that clothed the hillsides, and imparting a most welcome sensation of coolness to the atmosphere. They rode at a foot pace, first because they were in no hurry, and secondly because the path was narrow and rough, there being room only for two riders abreast; Carlos therefore led the way, with Jack and Dona Isolda following close at his horse's tail. They had not been ten minutes under way when they arrived at a spot the marvellous natural beauty of which caused Jack to exclaim aloud in his astonishment: for upon rounding a bend in the path they found themselves in a little amphitheatre, about five hundred yards across, the tree-clad sides of which rose precipitously to a great height on either hand, and were gorgeous with great clustering blooms of every imaginable hue, from purest white through every shade of colour to a deep rich purple that looked almost black where seen in shadow; while the air, almost motionless down in the hollow, was heavy with the mingling of a thousand exquisite perfumes. The floor of this amphitheatre consisted of a great basin of rock, partly filled with fine white sand brought down from the uplands during countless generations by the flow of the stream, the basin being brimful of crystal-clear water which came pouring and plashing into it from above over a series of miniature cataracts, the lowest of which, about twelve feet high, impinged upon a small ledge of rock which projected into the basin for the space of about a yard. "This," said Carlos, "is our swimming bath, to which we often come for a dip in the early morning; it is absolutely private, all this being our own property, and nobody but ourselves ever passes here. What think you of it, Jack; is it not perfect?"
