 those states. Our explorations upon the Plains lay directly
 west from the State of Missouri, by the Kansas river and 
 Smoky Hill Fork & thence passing over to the Arkansas 
 river which we ascended nearly to the base of the Rocky
 Mts. The botanical collections were, however, made upon
 this section entirely upon the Santa Fe road, lying between
 the Kansas and Osage rivers for 200 miles west of the State
 of Missouri, and then following the Arkansas river as above.
 All this territory is, of course, now within the [?] of
 Kansas Territory. Near the mountains we crossed to the
 south-side of the Arkansas river and ascended its
