When he found I really took an interest in him he threw himself entirely upon my friendship.  He clung to me like a drowning man.  He would walk with me for hours up and down the place of St. Mark—­or he would sit until night was far advanced in my apartment; he took rooms under the same roof with me; and his constant request was, that I would permit him, when it did not incommode me, to sit by me in my saloon.  It was not that he seemed to take a particular delight in my conversation; but rather that he craved the vicinity of a human being; and above all, of a being that sympathized with him.  “I have often heard,” said he, “of the sincerity of Englishmen—­thank God I have one at length for a friend!”

Yet he never seemed disposed to avail himself of my sympathy other than by mere companionship.  He never sought to unbosom himself to me; there appeared to be a settled corroding anguish in his bosom that neither could be soothed “by silence nor by speaking.”  A devouring melancholy preyed upon his heart, and seemed to be drying up the very blood in his veins.  It was not a soft melancholy—­the disease of the affections; but a parching, withering agony.  I could see at times that his mouth was dry and feverish; he almost panted rather than breathed; his eyes were bloodshot; his cheeks pale and livid; with now and then faint streaks athwart them—­baleful gleams of the fire that was consuming his heart.  As my arm was within his, I felt him press it at times with a convulsive motion to his side; his hands would clinch themselves involuntarily, and a kind of shudder would run through his frame.  I reasoned with him about his melancholy, and sought to draw from him the cause—­he shrunk from all confiding.  “Do not seek to know it,” said he, “you could not relieve it if you knew it; you would not even seek to relieve it—­on the contrary, I should lose your sympathy; and that,” said he, pressing my hand convulsively, “that I feel has become too dear to me to risk.”

I endeavored to awaken hope within him.  He was young; life had a thousand pleasures in store for him; there is a healthy reaction in the youthful heart; it medicines its own wounds—­

“Come, come,” said I, “there is no grief so great that youth cannot outgrow it.”—­“No! no!” said he, clinching his teeth, and striking repeatedly, with the energy of despair, upon his bosom—­“It is here—­here—­deep-rooted; draining my heart’s blood.  It grows and grows, while my heart withers and withers!  I have a dreadful monitor that gives me no repose—­that follows me step by step; and will follow me step by step, until it pushes me into my grave!”

As he said this he gave involuntarily one of those fearful glances over his shoulder, and shrunk back with more than usual horror.  I could not resist the temptation to allude to this movement, which I supposed to be some mere malady of the nerves.  The moment I mentioned it his face became crimsoned and convulsed—­he grasped me by both hands:  “For God’s sake,” exclaimed he, with a piercing agony of voice—­“never allude to that again; let us avoid this subject, my friend; you cannot relieve me, indeed you cannot relieve me; but you may add to the torments I suffer;—­at some future day you shall know all.”
