Our greatest Geographic interest in these States is centered in the projects for interoceanic canals. The scheme to cut the Isthmus of Panama, undertaken by the eminent French engineer, De Lesseps, has been beset with many difficulties, not the least of them arising from the improvident management of those having immediate charge of the works. It is impossible to foresee the eventual outcome of this great work, as all reports expressing decided views on the subject are suspected of a coloring from the personal opinions of the authors of them. The original plans have been modified to include locks for crossing "a summit level." This is stated to be only a temporary expedient to secure the opening of the canal at an early date, and that eventually the work will be completed on the original plan of a "through cut." It seems evident from the latest reports that work will be continued as long as money is forthcoming to meet the expenses, and as the modified scheme to overcome the high land by locks instead of a through cut, greatly simplifies the engineering problems, there is a probability of the canal becoming an accomplished fact. A second route by way of the San Juan River and Lake Nicaragua, that has also been under discussion for many years, has recently been energetically advocated by American engineers, with the result of the actual location of a line and careful cross-sectioning during the past year. A company has been formed and obtained a charter from the State of Vermont, and as it is represented to be backed by abundant capital, we may, ere many years, have the gratification of seeing an interoceanic canal opened under American auspices. Many speculations have been indulged in as to the probable effect of a canal through this Isthmus on the carrying trade of the world, the impetus it might give to the opening up of new commercial relations, and even the effect it may have in advancing our civilization to distant nations. Such speculations are hardly pertinent to this report, but we may well reflect upon the changes that have been wrought since the opening of the canal through the Isthmus of Suez, and conceive, if we can, the leveling up that may accrue to the political divisions of the western world from the same influences that will cut the channel through her Isthmus. South America has been free from serious agitation until a recent date; although some of the States have not failed to show the usual internal dissensions in political affairs. Late advices intimate a possible difficulty between Venezuela and England relative to the control of a large territory embracing the mouth of the Orinoco River, which, should it result in the permanent occupation of the disputed territory by the European power, may wield a marked influence in the development of this section of the continent.
