Some two years since, I had the honor to read before the Naval Institute, a paper in which I attempted to present a comprehensive view of the Interoceanic Canal question, as it then appeared in the light of the latest reliable information.
Since that time important additions to our knowledge concerning two proposed routes have been made, and my duty as a member of the Institute requires that I should acquaint it with the facts. It will not, however, be necessary that I should speak of the Panama route, since you will doubtless receive information concerning the results of the survey of that line by Commander Lull, from other sources.
I will therefore confine myself to a description of the route by way of the Atrato and Napipi rivers, giving you the information acquired by an expedition under my command that made a careful survey of that route during the winter just past.
For a general description of the country in which this proposed route lies, I would refer to my previous paper. I wish now merely to describe its physical features, and to discuss briefly the question of its adaptability to the construction of a ship canal.
