"H. L." Boston, Mass., writes: "I have read several pieces in your Monthly about hedges with wire fences, and I want very much to know if you have ever made a pleached alley, and if so, whether you used Lindens, European or American, or Willows, Bay or Golden, etc.; or what tree you used, and how much space one must allow for breadth of Lindens or Willows each side of the walk; whether they would be best trained on wooden trellis or wire trellis; also, how many years it would take to grow them over the walk. How wide should be the walk, how high the arch of trees ? I am made bold to give so much trouble by the good-natured replies I see in your journal constantly to similar inquiries".

[The Editor has had no direct experience in this work, and would be obliged if some correspondent who has, would answer these inquiries. There are, however, some general points that will be well remembered. There is a tendency in many plants to get naked at the bottom, and keep all the foliage at the apex, hence the plant employed for pleaching and arch training should be of those plants that have a natural tendency to keep the foliage to the ground. For small arch work there is nothing of this character superior to the Hornbeams, but the plant is too low a grower for the larger archways that are so effectually employed in Europe. These are mainly of the European Linden. The American Linden would do as well and better for our climate. As far as our memory extends, some of the most successful specimens of trained Lindens in our country, are at the Soldiers' Home, Dayton, Ohio, though there may be others not remembered just now. Wire ought to be good enough for training on. The trees might be planted twelve or fifteen feet apart. The height of the arch will depend on the width of the avenue.

If very high it will be difficult to prune or train. - Ed. G. M].
