the neighborhood were collected ; also stone implements,

in the year 1528; and the meagre remnants of a human 
form whose sepulchre we had rudely violated, may have be-

the remembrance of his wrongs, replied to the overtures of 
De Soto with words of scorn.

The following notes comprise an enumeration of the trees 
of the Rocky Mountains, etc., from Fort Benton, Nebraska,

and west to Fort Dalles, Oregon. 
ASH-LEAVED Marie (Negundo aceroides). The Box 
Elder reaches the Rocky Mountains at Fort Benton, but 
does not cross them there, no species reaching the Columbia

THirrihigua said, “I want none of their speeches nor promises; bring me their 
heads, and I will receive them joyfully.” Id., p. 60.
