When my uncle had gone, I sank into a chair and fell into a musing fit over all the changes a few hours had wrought in me. From a mere boy whose most serious employment was stocking the house with game or inspecting the kennel, I had sprung at once into man’s estate, was complimented for my coolness, praised for my prowess, lauded for my discretion, by those who were my seniors by nearly half a century; talked to in a tone of confidential intimacy by my uncle, and, in a word, treated in all respects as an equal,--and such was all the work of a few hours. But so it is; the eras in life are separated by a narrow boundary,--some trifling accident, some casual _rencontre_ impels us across the Rubicon, and we pass from infancy to youth, from youth to manhood, from manhood to age, less by the slow and imperceptible step of time than by some one decisive act or passion which, occurring at a critical moment, elicits a long latent feeling, and impresses our existence with a color that tinges us for many a long year. As for me, I had cut the tie which bound me to the careless gayety of boyhood with a rude gash. In three short days I had fallen deeply, desperately in love, and had wounded, if not killed, an antagonist in a duel. As I meditated on these things, I was aroused by the noise of horses’ feet in the yard beneath. I opened the window and beheld no less a person than Captain Hammersley. He was handing a card to a servant, which he was accompanying by a verbal message; the impression of something like hostility on the part of the captain had never left my mind, and I hastened down-stairs just in time to catch him as he turned from the door. “Ah, Mr. O’Malley!” said he, in a most courteous tone. “They told me you were not at home.” I apologized for the blunder, and begged of him to alight and come in. “I thank you very much, but, in fact, my hours are now numbered here. I have just received an order to join my regiment; we have been ordered for service, and Sir George has most kindly permitted my giving up my staff appointment. I could not, however, leave the country without shaking hands with you. I owe you a lesson in horsemanship, and I’m only sorry that we are not to have another day together.” “Then you are going out to the Peninsula?” said I. “Why, we hope so; the commander-in-chief, they say, is in great want of cavalry, and we scarcely less in want of something to do. I’m sorry you are not coming with us.” “Would to Heaven I were!” said I, with an earnestness that almost made my brain start. “Then, why not?” “Unfortunately, I am peculiarly situated. My worthy uncle, who is all to me in this world, would be quite alone if I were to leave him; and although he has never said so, I know he dreads the possibility of my suggesting such a thing to him: so that, between his fears and mine, the matter is never broached by either party, nor do I think ever can be.”
