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 River 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 
Schooleraft,’ 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
