No. 7. DEPARTMENT OF AGRICULTURE. 635 



Plane — Platinus Orientalis. 



Tulip Poplar — Siriodendron Tulipifera. 



Elm — Ulmus Campestris. 



These are all so Avell known that any comment on them seems 

 unnecessary; however, for the benefit of those who may be un- 

 acquainted with them, will say that these varieties have the follow- 

 ing good qualities : They are rapid growers, require very little prun- 

 ing after establishment, grow symmetrically erect, afford abundant 

 shade, are less liable to damage by storms than many other varie- 

 ties, their foliage is varied and beautiful, and are less liable to the 

 attack of insect enemies than many other species of trees. The last 

 named, however, in fact the entire family of elms, is an exception 

 to this; they are not so free from insect attacks, but being such a 

 grand and noble tree, and the distinct type of foliage being different 

 from any other, and peculiarly its own, repays any and all the extra 

 attention that be necessary to combat and exterminate its enemies. 



I regret to say, however, that several aboriculturists have given up 

 planting the elm on account of insect attacks. In my opinion this is 

 a wrong idea, for if all tree lovers were to give up the culture of 

 the elm, the species would become extinct. Such an event would be 

 a calamity. I for one, a member of Dame Nature's highest order, will 

 never submit to members of her lowest order, but will continue to 

 grow and plant elms, and fight for their supremacy over their 

 enemies.
