plc^s^eso : aiy on b ^ sev. .oin died, and the 
mortality would have been far greater but for the kind attention of Dr. 
Evans, who, though himself laboring under an exhausting diarrhoea, 
allowed himself no rest, but in the triple capacitv of physician, nurse and 
companion, was ever at the bed-^side of the sick, administering to their 
wants, and encouraging them by his cheering words. 
From Fort Pierre, Dr. Evans again visited the Mauvaises Terres, 
where in a short time he succeeded in obtaining a large collection of the 
fossil fauna of that region, even more extensive than his former one, 
and embracing a considerable number of new and interesting species! 
On his return to the Fort he set about preparing for. his long journey 
which from the hostility of the Blackfeet and other Indian tribes, to! 
gether with the difficulties incident to the route, was regarded by the 
Indian traders as extremely hazardous ; hence- it was exceedingly diffi- 
cult to find either guides or hunters willing to accompany him. After 
much persuasion, however, he succeeded in procuring the services of 
two hunters and a half-breed guide, they agreeing to go with him as far 
as the Flathead Village. With this meagre escort he started from Fort 
Pierre, but scarcely had he reached the borders of the Blackfeet country 
ere his hunters became alarmed, and unceremoniously left his camp 
during the night and returned to the Fort. Under these discouraging 
circumstances a person less courageous than Dr. Evans would have 
turned back but difficulties served only to develope the indomitable 
IS justly due the credit of having first called 
attention to the existence of such remains in that region by his excellent 
memoirs of Palasotheroid and other bones, published in Silliman’s Journal
