first white settlement. Nuttall returned to Philadelphia 

 with many and various species of plants and seeds, with 

 many valuable specimens of minerals and other objects 

 of natural history. 



Bradbury, upon his return to the Arikara village, 

 found the Astorians in active preparation for their jour- 

 ney across the continent by land. He was invited to ac- 

 company them to the coast, but on account of his large 

 collections and the uncertainty of obtaining tranporta- 

 tion by sea, he preferred to return to St. Louis with 

 Henry M. Brackenridge in one of the boats belonging to 

 Manuel Lisa, a prominent fur trader of St. Louis. 



Having finally returned to Liverpool in 1815, Brad- 

 bury published in 1817 a book on his Travels in the In- 

 terior of America, 1809-1811. In the preface to the sec- 

 ond edition of 1819 it is stated that Mr. Bradbury has 

 taken up his permanent residence in St. Louis. He was 

 visited by the members of Long's Expedition at his home 

 at Sulphur Springs, in the valley of the Biver des Peres, 

 not far from what is now Cheltenham. His name is 

 given in the city directory for 1821, but it does not ap- 

 pear in subsequent issues and no further information 

 has been obtainable of his whereabouts. 



Another naturalist who visited this section of the coun- 

 try early in the nineteenth century was Henry Rowe 

 Schoolcraft, 8 a conspicuous figure among the scientists 

 of the early part of the century. To him we are indebted 

 for the first account of the geological formations of the 

 great valley beyond the Alleghanies and of its mineral 

 wealth and resources. We are also indebted to him for 

 the discovery of the source of the Mississippi river in 

 Itasca lake. For many years, beginning with 1817, he
