I am looking for information regarding the economic themes that shaped Missourian immigration into Kansas Territory. A particular theme I am interested in is the "early grab" of woodlands by the Missourians. This is briefly described in Malin's "The Proslavery Background of the Kansas Struggle". I recall having run across an article that more prominently featured this theme and dealt with it in more detail, but I am having a hard time relocating this article (if it even existed). Any suggestions? Thanks very much for any assistance you can provide.
