Excerpt from Valley of the Rio Grande: Its Soil, Productions, Climate, &C., &C

IT is a singular fact, that the soil of this extensive valley is composed Of mineral constituents precisely similar to those which compose the Delta of the Nile, and there is scarcely a doubt that, under a proper system of culture, it will become equally productive.

The Rio Grande resembles the Nile In many remarkable features. It has its source in towering primitive mountains, composed of red granite, identical in appearance and geological structure with the material from which the imperishable monuments of the Pharaohs were hewn.

Below these mountains, at different elevations, are extensive formations of secondary limestone and sandstone vast fields of moving sand through which the river forces its devious way in its annual floods, by constantly changing channels; and broad plains covered, like those of Upper Egypt, with silicious pebbles, such as fiints, agates and chalcedony, intermingled with large petrified trees, such as are found near Cairo. Indeed, throughout its whole length and breadth, this extensive valley presents nearly the same geological characteristics as that of the Nile, and its soil, being made up' of the detritus of similar rocky formations, must be similar in its chemical constituents.
