There are several considerations which point out the present as the most auspicious moment for attaining the object in view. The profound peace with which Europe and the whole civilized world is now blessed, the abundance of capital in the money market, the present low rate of interest, and the difficulty of finding investments, are all favorable to the raising of the necessary funds; the immense strides which science has made in overcoming natural difficulties, once deemed insuperable, add to the means of accomplishment, while the growing importance of British Colonies in and about New Zealand, the inevitable impulse that recent events must give to the China trade,[2] and the efforts of all maritime nations to make establishments in the Polynesian Islands will render the Canal a certain source of profit and honor to those who will aid in its formation. Several parts of the Isthmus of America have been proposed for the communication between the two seas, such as the Province of Nicaragua, the Isthmus of Tehuantepec, &c.; but invincible obstacles occur in all those localities, while on the contrary the Isthmus of Panama is beyond doubt the most favorable point, according to the opinion of all the scientific and practical men who have visited that part of the new world.[3] We shall proceed, therefore, to describe that Isthmus as far as is necessary for the present purpose. The Isthmus of Panama[4] may be considered as extending from the Meridian of 77° to that of 81° W. of Greenwich. Its breadth at the narrowest point, opposite to the city of Panama, is about thirty miles. The general feature of the Isthmus on the map is that of an arc, or bow, the chord of which lies nearly east and west. It now forms a province of the republic of New Granada.
