not excelled by any tree yet tested. The widespreading low- 

 topped form is most common, and the grower who attempts to 

 prune western Kansas elms into an imitation of the Connecticut 

 elms is certain to find that even this hardy species may be 

 ruined by sun scald and insects. 





PLATE 20. White elm at Ogallah Station. 



The elms in the demonstration block at Ogallah have been 

 somewhat favored in their location, having been set in a slight 

 depression in the high prairie. This slight difference shows 

 with remarkable distinctness, the trees in the waterway being 

 much larger and better than the trees upon the slope, the 

 gradation being readily noticed. Twelve trees are above 

 twenty feet in height and five inches in diameter, the best being 

 twenty-five feet high and six inches in diameter. Occasional 

 specimens have been noted in many parts of the state, and in 

 every case where the trees have had even fair care a high de- 

 gree of success has been attained. At Offerle, on high prairie 

 soil, white elms have attained a diameter of eighteen inches, a 

 spread of forty feet and a height of thirty feet. For shade and 

 street trees the white elm is especially desirable. 



COFFEE BEAN. 



The coffee bean has proved able to adapt itself to a wide va- 

 riety of soils and conditions. In eastern Kansas it is usually 

 found near streams, but occasionally climbs to the higher parts 

 of ravines and sometimes to the high upland. It has not been 

 generally planted, but has succeeded in nearly every case where
