Nanz & Neuner, Louisville, Ky., write: "Through the carelessness of the New Gas Co. (water gas) we are losing a number of trees here on the principal streets, some as old as twenty and thirty years. Great many are completely dead, especially the Ailanthus, while Silver Maples and Lindens don't seem to suffer so much from the leakages in the pipes. But the leaves are turning yellow, and perhaps before long they will be dead also. Pipes are relaid now, and there is perhaps no further danger of seeing more trees killed. Can any remedy be employed to save the sick trees ? Will watering help, etc., to get the poisonous gas out of the soil ? If anything can be done please reply and oblige us. We will publish it in the daily papers so it will benefit all alike".
