FORESTRY AT THE EXPOSITION 



1065 



American Forestry have attracted my attention and 

 therefore I desire to ask where I can obtain some of the 

 seeds or transplants of the varieties and whether or not 

 you would recommend them for such an arid locality 

 as Western Nevada. 



A. J. P., Carson, Nev. 



A. Would suggest your writing to any of the forestry, 

 seed or nursery companies advertising in this magazine 

 for seeds or transplants. As to the availability of the 

 species you mention for such an arid locality as western 

 Nevada, I would not encourage the consideration of the 

 Sweet gum or the American beech, though you might be 

 successful with the European linden, which does well in 

 North and South Dakota where the rainfall is meager. 

 If the ground is irrigated this, of course, would have a 

 decided bearing on your planting, but the safest thing is 

 to stick to the cotton-wood, the hackberry or box-elder, 

 and the linden, as they will give you the best results. The 

 flowering Dogwood, while very beautiful, really needs 

 protection and considerable moisture and I would have 

 grave doubts of any success with it in Nevada except in 

 most unusual surroundings. 



DISCUSSION INVITED 



The Editor invites and would appreciate discussion, 

 through these columns, of the following questions, raised 

 by Mr. R. Brooke Maxwell, City Forester, Baltimore: 



"It would be interesting to have members of our 

 academy and readers of your department of American 

 Forestry to discuss two tree troubles which I have in 

 mind. The first is a trouble common with our lindens, 

 including the European (Tilia microphylla) and its va- 

 rieties, Dasystyla euchlora and Argentea, and the Ameri- 

 can linden {Tilia Americana) . The trouble is with the 

 leaves and for several years I have noticed that about 

 the 1st to the 15th of August these trees, a large majority 

 of them, lose their foliage and put on a second crop of 

 leaves. The trouble occurs not only on the footways, but 

 also in our parks where the conditions of growth are 

 ideal. I am inclined to think you are going to call the 

 trouble a physiological one due to excessive evaporation 

 and too little water, but this can hardly be the case this 

 year for we have had a season of unusually heavy rains 

 and the condition remains unchanged. Would you call 

 it the linden leaf spot {Gleosporium tiliae) ? The infec- 

 tion seems to be of too general a nature and too disas- 

 trous in its results to call it this. 



"The second trouble is with the leaves of sugar maple. 

 This is the same old trouble that tree men have been 



calling 'physiological,' caused by too little moisture and 

 excessive evaporation. The trouble occurs on both foot- 

 ways and in our parks. If it is due to unbalanced mois- 

 ture conditions why should a single tree in a large planta- 

 tion be affected and the others remain untouched? I 

 have heard it called by some a sugar maple blight. 

 Accurately speaking, I do not believe there is any such 

 disease. Might it not be the leaf spot which is common 

 to the Norway maple {Gleosporium apocryptum)?" 



ARBORISTS WILL MEET IN NEWARK IN JANUARY 



THE first annual meeting of the American Academy 

 of Arborists, formed about a year ago with the 

 aim of advancing arboriculture and landscape 

 forestry and maintaining the highest professional stand- 

 ard among its members, will be held in Newark on Janu- 

 ary 8 next, in appreciation of the work done by the 

 Newark Shade Tree Commission for the progress of 

 arboriculture. 



The sessions will open at 10 a. m. with a business 

 meeting. Addresses will be given as follows at the after- 

 noon session, which will open at 2 o'clock : "The Min- 

 istry of Trees," Carl Bannwart, secretary Newark Shade 

 Tree Commission ; "The Tree Faker," Hermann Merkel, 

 chief forester New York Zoological Park and presi- 

 dent of Academy of Arborists; "Fungus Problems of 

 Interest to Arborists," R. B. Maxwell, city engineer and 

 second vice-president of Academy of Arboriculture ; 

 "Arboriculture as a Profession," J. J. Levison, arbori- 

 culturist of Brooklyn Park Department and secretary of 

 Academy of Arboriculture. New and important prob- 

 lems in arboriculture then will be discussed by the mem- 

 bers. In the afternoon the session will be open to the 

 public. About 1905, some foresters began to specialize 

 in the care of street and ornamental trees. Since that 

 time many cities and towns have taken the matter up 

 and are now employing men to look after the trees on 

 their streets, parks and public grounds. Most of these 

 men work under the name of city foresters, foresters 

 and arboriculturists. Some of them are trained foresters 

 who have made a special study of shade and ornamental 

 trees grown under city and town conditions. Some are 

 not foresters at all but are landscape men who also have 

 made a specialty of shade trees and park development. 

 Others are self-educated men who are in the work be- 

 cause they have a natural liking for it. All these men 

 are valuable assets to the profession. 



Through the work of a few pioneers the general public 

 is becoming interested in the work, and a great demand 

 has been made for skilled service in caring for private 

 estates.
