Tlic bulletin also contains the lollowiiig statciiK-nls regarding the 

 origin of the Nebraska trees and shrubs: 



A close stiulyof tlip farts astotlip rtistribntion of our wooilyplants shows that nearly 

 all have prol>al)lv ini<ii:ite<l to the ]>laiiis from the Kast. Tliey have in soiiiecases done 

 no more than to get a little foothold in the extreme southeastern eonnties, to whieli 

 they have <'ome from the lieavy forests of Missouri. A f«'w have doiilitless erossed 

 the Missouri Kiver from western Iowa, although this numher is eviih-ntly very 

 small. Nearly all our trees have come up the Missouri bottoms and 8i)rea4l from the 

 southeastern comer of the State west and northwest. Possibly a few may have 

 come up the Hlue Kiver from Kausas, but these must eventually be traced to the 

 Missouri River bottoms at the mouth of the Kansas Kiver. 



The trees and shrubs which arc found only in the western ])nrt of the State 

 unquestionably came from the Rocky Mountains, and have sprea<l eastward to their 

 present limits. Only one of these, the biilValo berry, has spre.td itself over the 

 whole State. There is a probability that a careful examination of the blufls of the 

 Niobrara, Platte, and Republican Rivers will sliow several more of these Rocky 

 Mountain plants, which have come down with the river currents. It is singular that 

 so few of the western trees and shrubs have come down the streams, csjteciallv as 

 prevailiufj winds are also from the westerly parts toward the east. One certainly 

 woulil have sujqiosed it much easier for the Western trees to come df)wnstreani and 

 with the wind than for the elms, ashes, plums, etc.. to have gone up the streams 

 against the prevailing winds. 



I suspect the meaning of all this is that Eastern conditions are slowly advanc- 

 ing westward; that such climatic and other changes are slowly taking place upon
