"Niagara and Iguazu cannot be compared. The one is surrounded by cultivated parks and thriving modern cities, the other with the abandon of nature. Niagara makes a single leap over a precipice one hundred and eighty feet high, while Iguazu is broken in fall but far wider. Either one is a possession for any country to be proud of and neither one is worth a single quarrel. "We are to camp here for some days. I hope you little folk will have a nice time and I am not going to issue a lot of commands to spoil your pleasure. Only one thing is forbidden; you must never go away from camp without one of the servants unless you are with one of us grown people. Do you understand?" "Yes, sir," they all said, and he added, "I am sure I can trust you. The forest is full of all manner of animals and creeping things, and it would be very easy to lose your way, so that we could never find you again. Now, have all the fun you can for our week here will soon be over." What orgies of delight followed! The girls bathed in the stream and ran wild in the sunshine, happy and tanned, going into the forest with the boys, except when they were going hunting. Several days before their return home, the whole party went up to San Ignacio to see the ruins of the old mission in the heart of the woods. Huge trees mark the site of the flourishing town, where once were cheerful homes which only eighty years ago were burned. So well were these dwellings built that the ruins are in excellent preservation, and the children played hide-and-seek in and out of the deserted walls, their merry laughter waking the echoes of the past. Maria had taught them the game she called 'High Spy,' and they enjoyed it greatly, she most of all. [Illustration: "'I MUST NOT BE SILLY AND CRY,' SHE SAID TO HERSELF."] "Now then, Martim, it's your turn to be it," she said. "And you can't find me!" as she sped away to hide in some new and strange place. Before she knew it she had gone farther into the forest than she meant, and she did not know how to return. She turned this way and that, but there seemed no path. All about her the woods hemmed her in everywhere like a great green curtain. Then catching her foot in a swinging vine she fell and hurt her ankle. Frightened, she stood under a great magnolia to think. "I must not be silly and cry," she said to herself. "I can't have gone very far, and if I sit still they'll be sure to come and find me. If I go on I may just get farther and farther away. I am going to stay right here anyway, until my ankle is better," as she seated herself quietly. Maria was a brave child and old for her age, and she sat quite still, though the tears came into her eyes. Soon she grew very drowsy and could hardly keep awake, for the woods were full of soft, cooing sounds and at last she dropped asleep.
