In this department there are two stations, however, of such vital importance, that the considerable additional expense which will be required to place steam-boats on them from the outset, ought not to be taken into consideration. These are, first, the station between Jamaica and Chagres; and, secondly, the station between Jamaica, Cuba, and Vera Cruz. The first goes to connect the Great Pacific Ocean, and the coasts thereof, with Europe and the eastern coasts of America, and on which former coasts a steam mail communication has been already concerted. Through the channel from Panama to Chagres will be concentrated, as it were, into a funnel the whole movements, travelling and mail communications and money transactions of the western coasts of America, from California on the north, to Valparaiso on the south, the whole of which again must converge to and diverge from Jamaica.[2] The second station, or that from Cuba to Vera (p. 030) Cruz, is little inferior in importance to the other, that town and Tampico being the great outlets of the trade and the commerce, but more especially the outlets of specie from the kingdom or empire of Mexico. A steamer on this station becomes indispensable, in order to secure the safe conveyance of specie, because small sailing vessels would be liable to be attacked and plundered by pirates. With steamers all would be safe. [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
