well in tliis region, needing but little care to prevent the ill 

 effects of drought. The tree is often badly infected with the 

 fungus popularly known as cedar apples {Gymnosporangiiivi 

 niacropus). As a result all the neighboring apple trees were 

 found to be badly infected with the cedar rust. The ceda^- 

 has so many good qualities that the owners feel constrained 

 to retain their trees in spite of its bad qualities. The apple 

 crop however is not seriously considered as the region has not 

 been developed as a fruit country. 



Box elder {Acer ncgundo) has appearently always been 

 in much favor as it grows quickly and gives the maximum 

 amount of shade in the least time. It occurs planted as single 

 trees or in rows for windbreaks. 



Mulberry {Morns rubra) is frequently seen as a door- 

 yard planting, but more often as a hedge or w'indbreak. The 

 later plantings of mulberry seem to be the -French mulberry 

 {Morns alba). This one is often planted thickly in a row 

 and kept trimmed down to about four feet in height as an 

 ornamental hedge. 



Black locust {Robinia peudacacia) was not often seen 

 but it occurs as a windbreak or as a shade tree. It is very 

 pretty when in blossom but is subject to insect attacks and 

 then is unsightly. 



Honey locust {Gleditsia triacantJios) is not often plant- 

 ed. This tree has many good qualities and does not seem to 

 be subject to fungus or insect attacks. All the trees observed 

 were fine ones ; the dark green foliage presenting a pleasing 

 sight and they were apparently not affected by the drought. 

 This tree should be more frequently planted, using the thorn- 

 less variety. One farm about eight miles north of Riverdale 

 has extensive plantings of this species.
