[Footnote 2: Should the Colombian Government obstinately and ignorantly oppose the transmission of mails across the isthmus from Chagres to Panama, or propose to shackle this point of communication with unreasonable and inadmissible restrictions, then in that case there remains a point, it is believed, more practicable, safer, and more eligible, where the communication could be effected, namely, in the State of Guatemala, or Central America, by the River St. Juan's and Lake Nicaragua, both of which are navigable for vessels of any size. The south-west shores of the lake in question approach to within fourteen or fifteen miles of the Pacific, and this distance, in one place, through a valley nearly level throughout, and at but little elevation above the level of the sea. From Lake Managua, or Leon, the distance to the sea is still shorter, being, in one place, according to good maps, not more than eight to ten miles. From this lake also, and the capital, Leon, the distance north-west to Rialejo, a fine port on the Pacific, is twenty-three miles, and through an accessible, if not very easy country. The Government of the Republic of Guatemala, or Central America, would doubtless be ready to afford every facility to open such a communication, which would prove the greatest and most certain means of improving their country. Moreover, if a ready communication is once afforded, from any point on the east coast of America, in the places alluded to, it would speedily become the object and the interest of the Chilian, the Peruvian, and the Mexican Governments to watch and to see that the communication with the world to the eastward should not only be rendered secure, but be maintained. Also, with a communication opened in this quarter, such as it is believed can be opened, the commerce and communications between North America and Europe, and New South Wales, China, and all Eastern Asia, would most certainly, as it could most advantageously and expeditiously, be carried on by it.]
Two powerful steamers would be sufficient for both stations, in order to carry two mails each month. That steamer to run between Cuba and Vera Cruz, would always be in time with the return mails for the following packet from Europe; while that boat which runs between Jamaica and Chagres would, by returning immediately by the route afterwards pointed out, always be in time for the same packet at Jamaica. To stop at Chagres for the mails from the Pacific would not be advisable or proper, because the arrival of these mails at Chagres could not be calculated upon with any certainty. If at Chagres when the outward mail arrives, good and well, they would be immediately taken up and carried forward; but if not, then they would be brought forward by it on the next voyage, and in time for the following European packet.
