We rode over a comparatively level region in coming from the house of Senor Lima to this place, and though not giving evidence of so much fertility as that near the Rio Jahu, it is generally of good quality, and is well supplied with water for ordinary domestic purposes. There was no portion of useless land seen upon this route, and no campos have been encountered since leaving the town of Brotas. The timber throughout this plateau is of good size, and much of it very favorable for splitting to make fences, as the quarenta, which grows especially abundant near the fazenda at which we are stopped. This tree is very durable when made into rails, and has its name from the impression that it lasts during forty years. In entering the premises, I observed the neatest and most substantial fencing yet seen in Brazil, and was informed that the rails are of this material. One end of the rails is embedded in the earth, and they are arranged side by side in a perpendicular form, with a cross-bar of the palmetto running horizontally about two feet from the top, which is secured by being lashed continuously with the sipo vine. This sipo is a long and slender vine of surprising strength and flexibility, which is used for confining the rafters of houses, tying timbers together where pegs or nails would be used with us, baling cotton, and, indeed, for any purpose to which ropes might be applied. It is called in common parlance the Brazilian nail, and it is remarkable to what an extent it is made a substitute for nails.

It is particularly well suited for constructing these stake-fences, and no better enclosure can be devised for the protection of a crop against large or small intruders.

General Wood, Doctor Warne, and Mr. Snell parted from the rest of us at the house of Senor Lima, and went down to the mouth of the Jahu, and descended the river Tieté in canoes for two miles. They gave a favorable account of the general outline of the banks on each side, but found the channel of the river so shallow in several places that the canoes came in contact with the bottom, and it was requisite for the boatmen to draw them over by getting out into the water. There was one point at which there were rapids or falls, and they got out upon the shore, while those in charge of the canoes carried them over the fall, receiving them again below into the canoes.

This being a drought of many months continuance, the river is said to be lower than it has been before for twelve years, and the ordinary level of the water is stated to be six feet above its present state. It is thought by persons acquainted with the river, that there is sufficient water during the rainy months, to afford a passage for flat-bottomed propellers to Perecicaba, from which point there is a wagon-road to Campinas, and from thence the railroad will perhaps be available in a few years.

From the account received, and from my personal inspection of the river, I think there is but little prospect of navigating it with safety, and unless there be a practicable route for a railway to this region of country, its products must depend on transportation by pack-mules.

The elevated serra near Brotas is perhaps the most serious obstacle to a railroad, and it remains for engineers to determine whether this can be overcome.

If a line of railroad is extended to Araraquara, and can communicate with the Rio Jaceré below Cambury, then this section of country lying between the Tieté and Jaceré might avail itself of the Jaceré for navigation up to that point, and thus get an outlet for its products.

The Jaceré is represented to have a deep and open channel from its mouth up to Cambury; and all the rich region lying between it and the Tieté and extending along the Jahu would be better accommodated by effecting this result than to attempt to navigate the Tieté upwards.

Tuesday, November 7, 1865.

Having but a limited number of beds, our host provided some dried raw-hides which were spread upon the dirt floor, and about one-half of our party slept upon them, with their overcoats, &c., assisting to fill out the scanty supply of bedding. There was no particular inconvenience experienced except from the fleas, which found ready access to our friends upon the hides and interrupted somewhat the quietness of their repose. Mr. Snell and myself were perched upon a long high table, and being thus above the jumping height of a flea we fared very well. I have carried a blanket and pillow throughout my trip, and found them with my overcoat very convenient on this occasion. A bed had been assigned to me, but feeling that our good friend Senor Joaquim Lorenço should of all others be provided for, I persuaded him to occupy the bed, and I slept comfortably upon the table during the whole night.
