His first care, on arriving at Mount Vernon, was to ascertain the condition of his private affairs; his next to make a tour of more than six hundred miles through the western country, with the double purpose of inspecting some lands of his, and of ascertaining the practicability of a communication between the head waters of the great rivers flowing east and west of the Alleghanies. He travelled entirely on horseback, in military style, and kept a minute journal of each day's observations, the result of which he communicated, on his return, in a letter to the Governor of Virginia, which Mr. Sparks declares to be "one of the ablest, most sagacious, and most important productions of his pen," and "the first suggestion of the great system of internal improvements which has since been pursued in the United States." On a previous tour, through the northern part of the State of New-York, he had observed the possibility of a water communication between the Hudson and the Great Lakes, and appreciated its advantages, thus foreshowing, at that early date, the existence of the Erie Canal. In 1784, Washington had a final visit from Lafayette, from whom he parted at Annapolis, with manifestations of a deeper tenderness than the weak can even know. Arrived at home, he sat down at once to say yet another word to the beloved: "In the moment of our separation, upon the road as I travelled, and every hour since," (mark the specification from this man of exact truth,) "I have felt all that love, respect and attachment for you, with which length of years, close connection, and your merits have inspired me. I often asked myself, as our carriages separated, whether that was the last sight I should ever have of you? And though I wished to say No! my fears answered Yes!" He was right; they never met again, but they loved each other always. Lafayette's letters to Washington are lover-like; they are alone sufficient to show how capable of the softest feeling was the great heart to which they were addressed.
