Page 113 - Those rivers must be regarded as public navigable rivers in law which are navigable in fact. And they are navigable in fact when they are used, or are susceptible of being used, in their ordinary condition, as highways for commerce, over which trade and travel are or may be conducted in the customary modes of trade and travel on water.
Page 8 - In the general region north of the Potomac and Ohio Rivers and east of the Mississippi River, railway rates were established as a percentage, in proportion to distance, of the baserate plus fixed or terminal charges.
Page 111 - Appropriations have never been limited by Congress to cases falling within the specific powers enumerated in the Constitution, whether those powers be construed in their broad or their narrow sense. And in an especial manner appropriations have been made to aid internal improvements of various sorts, in our roads, our navigation, our streams, and other objects of a national character and importance.
Page 111 - States;' that is, for the purpose of paying the public debts, and providing for the common defense and general welfare of the United States. In this sense, congress has not an unlimited power of taxation; but it is limited to specific objects — the payment of the public debts, and providing for the common defense and general welfare. A tax, therefore, laid by congress for neither of these objects, would be unconstitutional, as an excess of its legislative authority.
Page 111 - The Congress shall have power to lay and collect taxes, duties, imposts, and excises, in order to pay the debts, and to provide for the common defence and general welfare of the United States...
Page 113 - ... whatever incidents or rights attach to the ownership of property conveyed by the government will be determined by the States, subject to the condition that their rules do not impair the efficacy of the grants, or the use and enjoyment of the property by the grantee. As an incident of such ownership, the right of the riparian owner, where the waters are above the influence of the tide, will be limited according to the law of the State, either to low or high water mark, or will extend to the middle...
Page 114 - So unfettered is this control of Congress over the navigable streams of the country that its judgment as to whether a construction in or over such a river is or is not an obstacle and a hindrance to navigation is conclusive. Such judgment and determination is the exercise of legislative power in respect of a subject wholly within its control.
Page 63 - The winter flow is so regulated as to make room for 39,000,000,000 cubic feet of water at the end of winter. This is the amount ordinarily to be expected in the spring floods. (d) From the spring thaw until the dry season of summer (ordinarily until about July 10) as much water is retained in the reservoirs as possible, subject to rules (a) and (b).
Page 113 - This title of the owner of fast land upon the shore of a navigable river to the bed of the river is, at best, a qualified one. It is a title which inheres in the ownership of the shore; and, unless reserved or excluded by implication, passed with it as a shadow follows a substance, although capable of distinct ownership. It is subordinate to the public right of navigation, and however helpful in protecting the owner against the acts of third parties, is of no avail against the exercise of the great...
Page 32 - River for the year amounted to 11,486,278 short tons and 47,205 passengers. The effect on freight rates of the slack-water system of the Monongahela is very great. This is particularly true for coal, which is the principal article of commerce, and is well shown by a comparison of the railroad rates for carload lots along this river and those along the unimproved Allegheny. There are many mines along the Monongahela River that can ship either by rail or water, and within a distance of 45 miles from...
