76 THE TREE DOCTOR 



Next to the Norway Maple, I would suggest the far-famed 

 American Elm, particularly for wider streets. Saying nothing 

 of the possibility of age and size of this majestic tree, is there 

 anything more desirable than the charm and grace of what is 

 seen in Photo 17? The Elm will adapt itself to a greater variety 

 of soils than any tree that I am acquainted with. It will thrive 

 in sand, gravel or clay, provided it can obtain sufficient moisture. 



"What about the Hard Maples?" Charming, glorious! if 

 they can be properly treated. Maples generally are spoken of 

 as "Hard" or "Soft" Maples. In speaking of the different va- 

 rieties of "Hard" Maples, I will omit the names and let the 

 camera show some difference in type. The large, brushy-top 

 tree in Photo 62 is a "Hard" or "Sugar" Maple; so is that in 

 63, and also in 64. The character of each one is quite marked, 

 but the most desirable type is that in 63. Look at its firm, lateral 

 arms. A veritable young giant, standing there ready to grapple 

 with the fiercest gales ! 



Next in order I would suggest the Sycamore. The Ameri- 

 can variety is hardy, adapts itself to almost any kind of soil, is 

 attacked but little by insect pests, and is one of the strongest 

 built trees we have. It seldom ever has a "crotch," but pro- 

 duces strong lateral arms, attached to the bole with a very firm 

 "shoulder." The European variety ("Plane Tree") is, perhaps, 

 a handsomer tree than the native variety. The "Pin Oak" has 

 recently gained great notoriety. It is a magnificent tree and 

 grows to a large size. If you introduce these into your commun- 

 ity, see that the local "Tree man" is banished or imprisoned be- 

 fore you plant them, or he will "whack" the tops off, destroying 

 the "leader" and ruin the tree as he did in Photo 65. 



The "White Oak!" How majestic! Don't plant the Lin- 

 dens and "Soft" Maples on streets, they are too frail ; nor the 

 drooping Linden ("Lime Tree"). How beautiful they are! 

 Just the thing on a lawn or in a park, with branches drooping 

 quite on the ground. See Photos 34 and 88. These are very 

 "crotchy," and I never saw a large one (in this country) that 

 had not been injured by the wind. 



"Carolina Poplar?" Oh, don't ever mention it unless it be 

 to plant around your barnyard ! 



I have mentioned a few of the very best trees suitable for
