A New York correspondent says: "The continuous close planting of trees on narrow city streets is objectionable, the best effects being produced by an occasional tree, a group, two set opposite, or a short double close row with open approaches. I shall never forget a street vista in Holland into which was projected, about midway of its length, probably from over a bordering wall, one splendid specimen of tree growth. The line of tall, picturesquely gabled houses, hedging in one side of this lane-like avenue, was unbroken, whilst in the other there were frequent openings through which the sun entered, laying down across the pavement and moving mass of people, bars of intense light, made very effective by the alternating ones of shadow."

[In connection with this hint, the Philadelphia city squares may be noted, where there are two or three times as many as there ought to be. One-half or two-thirds ought to be cut out. They kill one another and kill the grass. - Ed. G. M.]
