Medicines in excess become poisonous. The "New England Farmer" mentions the case of an orchard of one hundred and sixty thrifty Baldwins that were washed with a solution of a pound of potash in a gallon ot water. The owner lound, in two days, that he had killed the whole of his beautiful and valuable trees. Soapsuds or ashes in water are strong enough. Guano is an excellent thing for trees, and salt is sometimes good; but it is one of the easiest things in the world to kill trees with them in excess.
