KEEPS TREES IN CONDITION

Device of German Expert Provides for Their Systematic Watering and Ventilation. A very ingenious and practical device for assuring the trees on city sidewalks a sufficient supply of water, no matter how dry the season and how hard baked the earth, has recently been put in operation in 8 trass burg by Mr. Sauer, the city tree inspector. It consists of a tube of iron or lead bent Into the form of a ring large enough to encircle the stem of the tree. The earth Is removed so that this ring may be placed just above the roots, and la then filled In again, leaving the end of a pipe connecting with the ring projecting above the surface of the ground. The top of the ring is pierced with a large number of small holes, and a tin cover or shield prevents these from becoming stopped up with earth. By means of a funnel in the protruding end of the pipe any desired amount of water may be supplied to the roots without waste or loss of time. A further advantage, according to Prometheus, is the ventilation thus secured of the earth in the vicinity of the roots —Scientific American.
