A Delaware county, Pa., correspondent says: In the Monthly you have an interesting department of " Forestry," and I would thank you to ask under that head for counsel, from those who have had experience, for resuscitatingan old and ragged wood, where former owners have cut off the best timber, and winds, cattle, and neglect, have done much to spoil the rest; and yet as a rough piece of land adapted and best suited to be covered by timber, what kind of trees to plant to fill the ugly gaps, and how to make them grow? I have such a piece of wood, and as it is well located for timber and just where woods ought to be, I concluded to restore them by planting. Part is wet, and part hilly. Having an ambition for the best, I have tried to re plant with oaks. We all know this tree is uncertain of success. The young trees that stood transplanting, and lived, are at once attacked by a beetle. It stings the oaks in spots; starting near the earth, and going up the trunk six to eight feet. The tree at once bleeds profusely. This is followed by a ragged break longitudinal. On cutting into it the wood of the trunk is black and dead, some distance in from the bark, and a dead spot, showing plainly to the eye, follows, and spreads rapidly up and down the trunk.

Death of the tree surely follows, and no oak seems safe, even if it has lived and grown for two or three years. I presume there are not now living in my woods more than one in from eight to twelve of all I have planted. I have persevered for four years, and I must confess the beetles hold their own, and I must select some other trees. And the question I would ask, what are the sorts of trees recommended by others who have tried to perform the same task? I am in a section of country where the oak grows freely, and in some pieces of timber profusely. I don't like soft maples and such trees, of small value for timber. I prefer forest trees, if such can be induced to grow. It is quite likely some one has tried the experiment I am undertaking, and knows of some better means of success.
