The intelligent bright faces of the boys pleased us. They looked like little girls in their long cotton frocks of white, standing round the campfire watching yucas roasting. The youngsters noticed us much more than the men of the party, who were generally from twenty-four to thirty years of age. These were Mojos Indians, from the town of Trinidad. Our Canichanas crew spoke a different language, though they only live a short distance apart on the pampa. The Canichanas came from the town of San Pedro, and yet these people do not understand the language of each other.

When our men landed, I noticed they said nothing to the others. Our fire was built and camping ground was near theirs, but the Mojos boys and North Americans were the only ones disposed to be sociable. Mamoré seemed the favorite of both parties; they both fed him, and as be ran back and forth, receiving kindness from all sides, the dog became the cause of jealousy between the two crews.

The boys had little bows and arrows and small paddles, but they carried no game or fish—nothing but yuca to eat and water to drink. They were fat, straight, well-built figures, with a clear molasses-and-water-colored skin. When they smiled, their white teeth and handsome black eyes gave them an agreeable and healthful appearance. They were washed of dirt and paint. The savage custom of boring great holes in their ears and noses had been cast aside, and they appeared neatly in simple frock, with straw hat, bows and arrows. The dress is certainly an awkward one for a man, but it is a great protection from the musquitoes, while it keeps off the sun and night dews; they are cool and comfortable also.

The ancient bark dress seems to have been the custom all through the interior of this plate. The Indians of the lowlands dress in bark and cotton cloth, while those of the mountains use wool and the skins of animals. Leather is best in a dry climate and rawhide in a wet one. Straw hats are seen in the truly tropical regions, while cloth caps and fur hats are wanted in the mountains and cold countries. Where there are the greatest diversities of climate, there are required the largest assortment of goods.

Soon after leaving Masi, the banks of the river are seven feet high, with the appearance of an overflow of as much as five feet.

One of the Mojos Indians informed the ex-governor we could get up to the town of Trinidad by a small stream which flowed by the town. This interested our men, as they would be obliged to carry the baggage some distance over the plain on their backs.

They pulled with a will, and entering a small channel we crossed, with the current, from the Mamoré to the river Ybaré. The channel was four fathoms deep and just wide enough to pass.

The Ybaré is sixty yards wide, and has very little current, with twenty-four feet depth of water, though it is said this stream becomes very shallow in the dry season. Descending the Ybaré a short distance, we entered a stream only twelve feet wide, where the men found great difficulty in forcing the canoe against the current. The land on the left hand side of the Ybaré is an island formed by the channel we came through from the Mamoré.

After the men had been working for some time up stream, they rested, got breakfast, and cut several long poles, which were carefully stowed away in the canoe for the purpose of carrying baggage. A trunk is slung to the middle of the pole, and each end is placed on a man's shoulder.

At 9 a. m., June 1, 1852, thermometer 77°, wet bulb 72°; a short time after breakfast, we suddenly came where there were no trees. The men took their bow and stern lines and mounted the bank, and we followed; on gaining the top, there, stretched out to the far east, was a perfect sea of herd grass. As far as the eye could reach the land was as level as a floor; scarcely a tree to be seen except along the little stream we had been following, with a belief we were amidst a great wilderness of woods; but the clear light of day shone down upon an open pasture-field.
