We stopped at a collection of three or four huts called Oge, where there was a trapiche to grind sugar-cane; but the people only made bad rum of it. We tried to purchase yuccas and plantains; but though they had them, they did not care to sell. They only plant enough for their own necessities. Great quantities of yuccas are used to make their masato. Below this we passed a rancho on the right-hand side, where there was a fine field of maize. This is the first settlement we have seen on that bank; fear of the savages, (or Infidels,) as they are called, who dwell on that side, preventing it.

We stopped for the night at Juan Comas, a small village situated on a bluff of light sandy soil, on the left bank. The hills on the other side are much more bare than is common, having only a few small trees and scattering bushes on them. We were quite objects of curiosity, and most of the people of the village came in to see us; one man, a strapping fellow, came in, and after a brief but courteous salutation to me, turned to one of the women, and drove her out of the house with kicks and curses. He followed her, and I soon after heard the sound of blows and the cries of a woman; I suppose the fellow was either jealous, or the lady had neglected some household duty to gratify her curiosity.

August 18.—Just below Juan Comas the river has one hundred yards of width and forty-two feet of depth. This part of the river is called the "well" of Juan Comas; it is half a mile in length, and the current runs but one and a quarter mile the hour. The hills terminate just below this, and we have the country flat on both sides. We passed some rocky hills on the right-hand side, in one of which is a cave called "Puma-huasi," or Tiger house. It is said to be very extensive. Soon after we passed the mouth of the river Hunanza, a small stream coming in on the Infidel side of the river. Our popero says that the Infidels dwell near here, and the people of Tarapoto go a short distance up this river to capture the young Indians and take them home as slaves. I believe this story; for I found servants of this class in Tarapoto, who were bought and sold as slaves. Slavery is prohibited by the laws of Peru; but this system is tolerated on the plea that the Infidel is christianized and his condition bettered by it.

It is very easy for only a few white men, armed with guns, to rob the savages of their children; for these rarely live in villages, but in families of at most three or four huts, and widely separated from each other. They never assemble except for the purpose of war; and then the sound of a horn, from settlement to settlement, brings them together. They are also a timid people, and will not face the white man's gun.

It is possible that the story of the popero is not true, and that the whites may buy the children of the Indians; but if so, I imagine that the advantages of the bargain are all on one side.

Below the mouth of the Hunanza we have the same comparatively bare hills that I noticed opposite Juan Comas. They present ridges of red earth and dark stone, which curve from the south towards the northeast, and are elevated in that direction to about 20°. I suspect that they have veins of salt, particularly as the salt hills of Pilluana are of the same range, and present at a distance nearly the same appearance.

The hills of Pilluana, which we now soon passed, have their base immediately upon the river, on the right-hand side. They are about three hundred feet in height, and stretch along the banks of the river for a quarter of a mile. The salt shows like frost upon the red earth at a distance; but seen nearer the heavy rains seem to have washed away the loose earth and left nearly the pure salt standing in innumerable cone-shaped pinnacles, so that the broken sides of the hills look like what drawings represent of the crater of a volcano, or the bottom of a geyser. Where the hills have been excavated, beautiful stalactites of perfectly pure salt hang from the roof in many varieties of shapes. There are much higher hills back of these, that appear also to contain salt; so that there seems a supply here for all people and for all time.

We passed the mouth of the river Mayo, that comes in on the left between moderately high hills, and five minutes after arrived at Shapaja, one of the ports of Tarapoto. The river, just above the junction of the Mayo, narrows to forty yards, has thirty and thirty-six feet of depth, and increases much in velocity. This is preparatory to its rush over the "Pongo," a strait of forty-five miles in length, where the river is confined between high hills, is much broken with malos pasos, and has its last considerable declivity.

Shapaja has twenty houses, mostly concealed in the high groves of plantains which surround them. Nearly all the men were away fishing, but the women (as always) received us kindly, and cooked our supper for us.
