“ numbers in the Louisiana Gazette I shall be more than compensated for the little labour & pains I have bestowed on it . . .”

Jefferson replied on May 11: “ I duly recieved your favor of Mar. 1. with the map it covered, for which be pleased to accept my thanks. every information of that country is acceptable as we know much less of it than either our duties or interests require . . . not being a subscriber for the Louisiana gazette, it is rarely seen in this quarter. indeed I am giving up the reading of newspapers in order to be able to indulge myself with reading which is more agreeable. Accept the assurances of my respect. ”

Jefferson’s bill from John March of Georgetown contained under date May 16, 1805, the entry: “ To pasting a Map of South Carolina 1.00 ”

This chart was sent to Jefferson by N. Marshall of Christ Church Parish, So. Carolina, on October 29, 1803: “I do myself the honor of presenting you, with an accurate chart of the coast of West Florida and Louisiana, including a survey and soundings of the Mississippi river, extending considerably above New Orleans. It was sent to me a few days ago, by a gentleman who married the widow of M ^r. Gauld, by whom the chart was made. I hasten to send it to you, as, if there be none such in possession of the administration it may be of some service, to the navigation of The New World, w ^h. you have lately obtained for us; and tend to appreciate, the advantages of an acquisition, in every View so immensely valuable to the United States.

"Wishing, that it may prove in any respect, beneficial to the Governm ^t. and acceptable to you, I remain, with the highest res ^t Y ^r. most obd ^t. s ^t.”

Jefferson acknowledged its receipt on December 24: “ Th: Jefferson presents his respectful salutations to mr Marshall and his thanks for the Chart of the coast of Florida, & mouth of the Missisipi which he has been so good as to send him. at a time when we are endeavoring to acquire exact knolege of that country, in order to make our first arrangements understandingly, so accurate a chart whose existence was not before known here, is doubly precious, and may render m ( ^~ r) Marshall’s kind attention really useful to the public.”

This map has a separate entry in Jefferson’s dated manuscript catalogue: Olmedilla’s map of S. America by Faden. 6. sheets.

It is possible that Jefferson owned the original Spanish edition of this map, published in Madrid in 1775. In December 1786 he wrote a short article headed Observations for the republication of the map of South America by Don Juan de la Crux Cano , 1 page in his handwriting, and with 3 small maps of South America drawn by him to scale.

A reproduction by William Faden was probably the subject of Jefferson’s inquiry in a letter to James Madison at Montpelier, Virginia, dated from Philadelphia June 28, 1791:
