* * * * * On the following day, about one o'clock, Mr. Markham, a gentleman of fortune residing in the northern environs of London, received the following letter:-- "The inscrutable decrees of Providence have enabled the undersigned to warn you, that this night a burglarious attempt will be made upon your dwelling. The wretches who contemplate this infamy are capable of a crime of much blacker die. Beware! "AN UNKNOWN FRIEND." This letter was written in a beautiful feminine hand. Due precaution was adopted at Mr. Markham's mansion; but the attempt alluded to in the warning epistle was, for some reason or another, not made. CHAPTER IV. THE TWO TREES. It was between eight and nine o'clock, on a delicious evening, about a week after the events related in the preceding chapters, that two youths issued from Mr. Markham's handsome, but somewhat secluded dwelling, in the northern part of the environs of London, and slowly ascended the adjacent hill. There was an interval of four years between the ages of these youths, the elder being upwards of nineteen, and the younger about fifteen; but it was easy to perceive by the resemblance which existed between them that they were brothers. They walked at a short distance from each other, and exchanged not a word as they ascended the somewhat steep path which conducted them to the summit of the eminence that overlooked the mansion they had just left. The elder proceeded first; and from time to time he clenched his fists, and knit his brows, and gave other silent but expressive indications of the angry passions which were concentrated in his breast. His brother followed him with downcast eyes, and with a countenance denoting the deep anguish that oppressed him. In this manner they arrived at the top of the hill, where they seated themselves upon a bench, which stood between two young ash saplings. For a long time the brothers remained silent; but at length the younger of the two suddenly burst into tears, and exclaimed, "Oh! why, dearest Eugene, did we choose this spot to say farewell--perhaps for ever?" "We could not select a more appropriate one, Richard," returned the elder brother. "Four years ago those trees were planted by our hands; and we have ever since called them by our own names. When we were wont to separate, to repair to our respective schools, we came hither to talk over our plans, to arrange the periods of our correspondence, and to anticipate the pursuits that should engage us during the vacations. And when we returned from our seminaries, we hastened hither, hand-in-hand, to see how our trees flourished; and he was most joyous and proud whose sapling appeared to expand the more luxuriantly. If ever we quarrelled, Richard, it was here that we made our peace again; and, seated upon this bench, we have concocted plans for the future; which, haply, will never now be realised!"
