Artificial Methods for Colouring Trees in Course of Growth Philadelphia, Nov. 9.
By feeding dye to, the: iving wood, according to Mr. S. Weimberg, a chemist of this city, trees can be coloured in 32 different shades, including apple green, divd green, ebony, weathered oak and salmon pink.
Experiments with a dye, which Mr. Weinberg has discovered, are being conducted in the botanical gardens of the University of Pennsylvania with three trees which have been presented to him by the.department of botany.
Introduced into the base of the tree, the dye is diffused throughout the branches by the natural functioning of the tree, Mr. Weinberg said. (Evidence is furnished by the presence in the botanical gardens of a dark blue tree, a vivid green poplar amd a salmon pink maple.
Assisted by Dr. Herbert Renner, of Germany, Mr. Weinberg also has experimented with a pore apple tree in Lansdowne, Pa.—Reuter.
