According to the Rural New Yorker, the Japan maples tested on the grounds of the editor "have not proved hardy during the past winter." In the vicinity of Philadelphia the numerous varieties show so much sameness of character that only one kind may be said to be popular - "Acer Jap. atropurpureum," as it is popularly called, or Japan blood-leaved maple. We have seen, perhaps, four hundred of these this spring without knowing of one to be injured. Passing along in the street-cars through Germantown, one may now see a pretty plant, some three feet high, on the grounds of the editor of the Germantown Telegraph, in full, healthy leaf, after total exposure all winter. On the writer's grounds is one five feet, also wholly uninjured, though standing alone on a very exposed place on the lawn. We fancy the experience noted by the Rural New Yorker is exceptional.
