FOREST TREES AND SHRUBS. 87 



Found in less numbers south of the Platte. Have seen it near the 

 west line of the State, on the Ariekaree, and on the Niobrara as 

 far as the ioi° meridian. Also found on the Elkhorn and the Loup 

 and Blue Rivers. 



22. Red Ash {F. pub esc ens?) Very rare in eastern Nebraska. 

 Have met with it sparingly on the Republican, Ariekaree, and on 

 the Niobrara. Occasionally found on the Elkhorn and Loup. 



2^. Green Ash (F. viridis.) Medium sized. Common in east- 

 ern Nebraska. Found a few in southwestern Nebraska, on the 

 Ariekaree, on the Niobrara, Loup, Elkhorn ank Bazile. 



24. Black Ash (F. sambucifo/ia.) Rare. Found it for the first 

 time during the last few years near the Nemaha, in Richardson 

 County. 



25. Blue Ash (F. quadrangulata.) Tree here of medium size. 

 Next to White Ash in abundance. Most frequently found in south- 

 eastern Nebraska. I have seen a few of them on the Republican, 

 Elkhorn, Loup and Niobrara. 



26. Slippery or Red Elm (Ulmus fulva.) Found widely spread, 

 but nowhere very abundant over eastern Nebraska. It is apt to 

 be met with in timber belts along water courses. It is met with 

 at intervals along the Republican, Nemaha, Elkhorn, and on the 

 Niobrara. 



27. White Elm ([/. Americana.) Same localities in the main 

 as the last, but more abundant. 



28. Cork White Elm (£/". racemosa.) A few in Dakota and 

 Dixon Counties. Still more rarely met with in Cass, Otoe and 

 Nemaha Counties. Found a few on the Niobrara, east of the 

 mouth of the Snake river. A fine specimen on Mr. Master's 

 grounds, a few miles east of Nebraska City. 



29. Wahoo Elm (£/. alata.) Rarest of all our elms. Have 

 only seen three specimens in Nebraska — one in Cass and two in 

 Richardson County. 



30. Hackberry (Cc/cis occidentalism) Common in eastern Ne- 

 braska. It is sparingly represented on the Republican, is more 

 abundant on the Niobrara. A few are also found on the Elkhorn 

 and the Loups. 



31. Red Mulberry (Morus rubra.) Found sparingly all along 

 eastern Nebraska, and generally on the timbered bluffs of the Mis- 

 souri. The finest trees occur in Dakota and Dixon counties. It 

 also occurs on the Niobrara as far west as the 101st meridian.
