It is one of the regrets of planters in this region of Philadelphia that we cannot have the grand Elms of our Eastern States, because of the terrible attacks made on them by insects. And just here let me ask the wise men who made the nurseries for the"park," if they know of this sad depredation, for we see they are setting out vast numbers of the attacked - and therefore useless for ornament - Elm trees. But this apart, for time is to test the wisdom brought to bear on our park planting. I want Mr. Meehan's opinion as regards the freedom of the Slippery Elm, Ulmus fulva, from insects. My own experience is that it is free from attack, and if so, as it has a weeping habit, it will be invaluable in the Middle States. I have a specimen equal to any of the great ornamental Elms of New England, and I learn with pleasure, Mr. Editor, that you also have a perfect tree unattack'e'd by enemies. But more, I hear that you and Mr. Parsons have propagated largely from this, and I want to know all that you know on the subject.

[The Slippery Elm in this region has its leaves badly riddled by a small beetle - a species of Galeruca - during the latter end of Summer; but the trees do not look near so shabby afterwards as other species do after similar attacks. Chestnut avenue, Germantown, has its sidewalks planted with them. They are now about twenty years old, and are very beautiful. - Ed. G. M.]"
