[The following letter, written by a distinguished President of the oldest College in Virginia, has been already or rather formerly before the public;--but no apology is necessary for transferring it to the columns of the "Messenger." Its elegant style and still more excellent sentiments, will always command admiration,--and we doubt whether we could render a more essential service to society than to republish it annually, in order that every young married lady (at least within the range of our subscription) should receive the benefit of its precepts. Certain we are, that more wholesome advice conveyed in more agreeable language, we have seldom seen contained in the same space. It is of itself a volume of instruction, and we do most cheerfully recommend it to the softer sex, whether married or single; for the married may profit by it even after years of conjugal tranquillity--and the single may at least _expect_ to profit. It is more especially applicable, however, to her who has just sworn her vows on the altar of hymen--whose life of bliss and peace, or misery and discord, may depend upon the first six or twelve months of "prudent, amiable, uniform conduct." Let it not be understood, however, that we are believers in the doctrine, that the pleasures of the matrimonial voyage are wholly dependant upon the conduct of the lady. She is but the second in command, and still greater responsibilities rest upon him who stands at the helm and guides the frail bark of human happiness. We should indeed be thankful if some of our highly gifted and experienced friends would prepare a _counterpart_ to this valuable letter of advice, designed more particularly for the edification of such of us lords of creation as have either contracted or are likely to contract the nuptial bond. As to the old bachelors they are an incorrigible race, upon whom such advice would be wasted, and therefore they need not trouble themselves to read it.] ADVICE FROM A FATHER TO HIS ONLY DAUGHTER. WRITTEN IMMEDIATELY AFTER HER MARRIAGE. _My dear Daughter_,--You have just entered into that state which is replete with happiness or misery. The issue depends upon that prudent, amiable, uniform conduct, which wisdom and virtue so strongly recommend, on the one hand, or on that imprudence which a want of reflection or passion may prompt, on the other. You are allied to a man of honor, of talents, and of an open, generous disposition. You have, therefore, in your power, all the essential ingredients of domestic happiness; it cannot be marred, if you now reflect upon that system of conduct which you ought invariably to pursue--if you now see clearly, the path from which you will resolve never to deviate. Our conduct is often the result of whim or caprice, often such as will give us many a pang, unless we see beforehand, what is always the most praiseworthy, and the most essential to happiness.
