"S. W. N.," Philadelphia, writes : " Please inform me through your journal what kind of trees are most suitable in this country for a pleached walk, also any necessary information concerning the planting of one, will be acceptable, and if there is a successful one in the neighborhood of Philadelphia."

[By pleached walks we understand walks that are bordered by trees which have their branches plaited together, so as to present a flat green surface. For this purpose the different willows are often employed in Europe - at least for making pleached fences - but few kinds under culture are strong enough for an arbor. The Linden would be best for this purpose. This is often employed in Europe, but the Editor has noted but few instances in America - one of these few being in the grounds of the Soldiers' Home at Dayton, Ohio - though that tree is trained rather as a screen than as an arbor. - Ed.
