Note 17 — SPANISH POLICY IN MISSISSIPPI AFTER THE TREATY OF SAN LORENZO.

Ellicott had made the surveys locating the limits of the District of Columbia, in 1791 (Chas. Burr Todd's Story of Washington, 21). The year following he was appointed to draft and publish a plan of the Federal City (Ib. 30). He also established the Meridian of Washington, conducted several other important public surveys and served a number of years as Surveyor General of the United States. In 1813, General Armstrong appointed him Professor of Mathematics in the United States' Military Academy at West Point, which position he held for several years. He was in constant communication with the National Institute of France and contributed to the Transactions of the American Philosophical Society. His official dispatches while engaged as Commissioner for locating the boundary between the United States and Spain may be found in the American State Papers, Foreign Relations, Vol. II. A more extensive account is given in narrative form in Ellicott's Journal, published at Philadelphia, in 1803. All his writings with reference to Mississippi must be read with caution, since they exhibit intense partisan animus.
