Página 146 - An act to provide for the appointment of a commission of engineers to investigate and report a permanent plan for the reclamation of the alluvial basin of the Mississippi River subject to inundation," I appointed a commission of engineers.
Página 7 - I have the honor to transmit herewith the report of the commission of engineers appointed in compliance with the act of Congress approved June 22, 1874, to investigate and report a permanent plan for the reclamation of the alluvial basin of the Mississippi River subject to inundation.

Página 146 - Army, and of the secretary, shall be paid upon the approval of bills for the same by the Secretary of War.

The daily oscillations at Cairo and at New Orleans, the former recorded by the engineers of the Cairo City Company, and the latter by Mr. Bayley, are represented upon the accompanying Plate I.
Página 52 - The next point where an accession to the flood wave could have occurred is Napoleon, just below the joint mouths of the Arkansas and White Rivers. The oscillations at Beulah (see Plate) represent very nearly those which must have occurred at this locality. Unfortunately the cut-off which was made here in 1803, renders it impossible to apply a close analysis to the water-marks of the two floods.
Página 113 - At Chattanooga the rise began on March 4, overflowed banks on March 8, and attained height on March 11, being 53 feet above low water and 15.5 feet above the high water of 1847, the highest on record. The river fell with equal rapidity to usual level.
Página 42 - For any given stand there is usually more water passing in a long and rapid than in a short and slow rise; but this is not always the case, the discharge being governed by the relative stage of the water in the channel above and below. 3. The maximum discharge...
Página 114 - April 17, about 3 inches of rain. On April 1, the river was at usual summer level, but a sudden and excessive (10 feet) freshet in the Niobrara raised it rapidly. Combined with the rise above, this freshet raised the Missouri, on April 18, to a point 1.5...
