Under these embarrassing circumstances my associates evinced the...
Side 30 - In these mountain formations, which border the great plains on the west, are to be found beautiful flowing streams, and small rich valleys covered over with fine grass for hay, and susceptible of cultivation by means of irrigation. Fine timber for fuel and lumber, limestone and good stone for building purposes are here abundant. Gold has been found in places in valuable quantities, and without doubt the more common and useful minerals will be discovered when more minute examinations are made.
Side 27 - Coal-Measures, they hold a position above the workable beds of coal, and that it is not probable a valuable seam of coal will be found north of the southern line of Nebraska. A bed of coal of inferior quality has been wrought near Leavenworth City, Kansas Territory, but it holds a lower geological position than the limestones of the southern portion of -Nebraska, the dip of the strata being toward the northeast.
Side 77 - Yellow silicious marl, similar in its character to the loess of the Rhine, passing down into variegated indurated clays and brown and yellow fine grits ; contains remains of extinct quadrupeds, mingled with those identical with recent ones ; also a few mollusca, mostly identical with recent species so far as determined. Most fully developed along the Missouri river, from the mouth of the Niobrara to St. Joseph ; also in the Platte valley and on the Loup Fork.
Side 41 - ... minerals. In describing the tributaries to the Niobrara, I shall begin at the mouth and take the north side first. The Ponka river, which has a very fine, well-wooded, and fertile valley, runs into the Missouri about five miles north of the Niobrara, in latitude 42° 48
Side 69 - They include so many highly organized plants, that were there not among them several genera exclusively Cretaceous, I should be disposed to refer them to a more recent era." " A single glance is sufficient to satisfy any one they are not Triassic. Up to the present time no angiosperm dicotyledonous plants have been found in rocks older than the Cretaceous, while of the eighteen species which comprise your collection sixteen are of this character.
Side 79 - Light gray fine sand, with more or less calcareous matter, passing down into an ash-colored plastic clay, with large quantities of quartz grains disseminated through it, sometimes forming aggregated masses like quartzose sandstone cemented with plastic clay ; then an ash-colored clay with a greenish tinge, underlaid at base by a light gray and ferruginous silicious sand and gravel, with pinkish bands. Immense quantities of silex in the form of seams all through the beds. Titanotherium Bed.
Side 3 - Very respectfully, your obedient servant, AA HUMPHREYS, Brigadier General and Chief of Engineers.
Side 62 - Explorations under the War Department. Explanations of a Second Edition of a Geological Map of Nebraska and Kansas, based upon Information obtained in an Expedition to the Black Hills, under the Command of Lieut. GK Warren. Top.
Side 12 - ... rivers, as the time and means will permit ; and to examine the Niobrara or 1'Eau qui Court river, upon your return route, for the purpose of ascertaining its character and resources and the practicability of locating a road along it, leading from the Missouri river to the South Pass, or from Fort Randall to Fort Laramie The sum of twenty-five thousand dollars is set apart from the appropriation to defray the expenses of the expedition, which amount your expenditures must not exceed. The commanding...
