An Exposition of the Errors and Fallacies in Rear-Admiral Ammen's Pamphlet Entitled (Classic Reprint)

Excerpt from An Exposition of the Errors and Fallacies in Rear-Admiral Ammen's Pamphlet Entitled

The principal rock cuttings to be encountered near the summit will be in a clay slate formation, limestone appearing at a lower elevation, and granite in the higher ranges on each side of the line. A care ful instrumental survey of the bar at the mouth of the river shows that there is at ordinary tide, fifteen feet of water over it. Surveys and soundings made during the last thirty years give conclusive evidence that this bar has changed very little during that time. Borings to the depth of twenty-six feet encountered no other material than sand and clay, much the larger portion being sand; a stratum of clay was found at the bottom of the borings. This bar has a striking resemblance to the bar at the mouth of the South Pass of the Mississippi river, except that it has less than one-fourth the distance across it, from twenty-six feet depth of water on the inside to the same depth on the outside, and it can be deepened by the same methods that gave such remarkable results at the mouth of the Mississippi river.

The statements made quite frequently by Admiral Ammen that no actual location and profile have been made evidently need no further discussion, nor do any of the arguments, drawn from these misstatements, require further notice.
