Show WORKS INJURY TO TREES; Seems Little Doubt That Tar Dust, Han the Ef.'ect of Withering j the Leaves. ; Mr. W. A. MurriU, assistant director! of the New York botanical gardens,, has sailed for Europe to find out if tar dust really Injures shade trees. A com-j mittee appointed to investigata the; problem In Pari;; has reported that it does. If Doctor Murrill's Investigations; (confirm this it will be necessary to change the park policy of New York.; Suburban towns along the main highways high-ways also will be affected because oS. the tar placed in the roadways to Jnake them smoother for automobile' traffic. Before sailing Doctor MurriU said that he was going to Paris with a perfectly per-fectly unbiased mind. He had never hearfl or seen anything that would, make him believe that tar dust hurt; New York's trees, but he admitted tar; . had a great many poisonous proper-, ties. "The Paris committee," he went on to say, "reported that the tar dust in, the Bois de Boulogne had withered the leaves on the trees there and made them fall prematurely. That report is worthy of attention, because the trees in Paris are better than in any other large city in the world. They are apt, iio.wever, to turn brown rather early and Americans going there in July and August are disposed for that reason rea-son to think the trees are inferior to those in New York. There are mora trees in Paris and they are more intelligently in-telligently planted and better cared for than ours." |
