partially and superficially known. The chief actor in them wrote much, but
printed nothing; and the published writings of his associates stand
wofully in need of interpretation from the unpublished documents which
exist, but which have not heretofore been used as material for history.

This volume attempts to supply the defect. Of the large amount of wholly
new material employed in it, by far the greater part is drawn from the
various public archives of France, and the rest from private sources. The
discovery of many of these documents is due to the indefatigable research
of M. Pierre Margry, assistant custodian of the Archives of the Marine and
Colonies at Paris, whose labors, as an investigator of the maritime and
colonial history of France can be appreciated only by those who have seen
their results. In the department of American colonial history, these
results have been invaluable; for, besides several private collections
made by him, he rendered important service in the collection of the French
portion of the Brodhead documents, selected and arranged the two great
series of colonial papers ordered by the Canadian government, and
prepared, with vast labor, analytical indexes of these and of
supplementary documents in the French archives, as well as a copious index
of the mass of papers relating to Louisiana. It is to be hoped that the
valuable publications on the maritime history of France which have
appeared from his pen are an earnest of more extended contributions in
future.

The late President Sparks, some time after the publication of his life of
La Salle, caused a collection to be made of documents relating to that
explorer, with the intention of incorporating them in a future edition.
This intention was never carried into effect, and the documents were never
used. With the liberality which always distinguished him, he placed them
at my disposal, and this privilege has been, kindly continued by Mrs.
