Rev. J. I., Salem, N. J., writes : " I was deploring in Philadelphia the other day to a friend the probable loss of some beautiful elm trees in our church yard, when he said at once, 'why do you not write to the Gardener's Monthly? The editor will tell you all about it.' Adopting his suggestion, I write. These trees are large and for two or three years have been sickly. The first evidence of disease is seen in the bark of the trunk which leaks the sap in large quantities. The bark becomes saturated from the upper part, from five or six feet from the ground, to the breadth of six or eight inches. Then the leaves wilt, droop, and drop. They re-leave, but show signs of weakness. The ends of the limbs die and so do our hopes. Two or three of our trees are in this condition, and this Spring another one is beginning to leak. If you can suggest any remedy, you will confer a very great favor upon our congregation as well as upon all the people of our little city who admire beautiful things. I shall be very glad to hear from you, and whatever suggestions you may make shall be carried into effect if within our power".

[We are not able to help our correspondent much on this occasion. The exudation is probably from the work of some wood-boring insect. In this case it may be traced by running in wire and crushed. The falling of the leaves in Summer, after they have been skeletonized by the elm slugs is another matter, and there is no known remedy for it. - Ed. G. M].
