For the same reason that woman surpasses man in conversation, she is superior to him in epistolary composition. Her letters are generally more varied, more lively and impressive, more replete with interesting facts and details, than those of our sex. A gentleman, in writing a mere letter of friendship, is engaged in a business which rather breaks in on his habits, and interrupts for a time the accustomed routine of his thoughts and tastes. He is very apt to run off upon the general news of the day, and commence prosing upon some subject which we would find perhaps infinitely better handled in the public prints than in his letter. He has no variety; he forgets to tell us of our friends, and of what they are doing and saying. He forgets that we have hearts, and thinks only of our heads. He omits to mention trifles, because he considers them "light as air," when some of these trifles might touch a chord that would vibrate to the heart, and fill the soul with joy and gratitude. When Mr. Dacre writes to the Duke of Fitzjames, in the Young Duke, and says in conclusion, "_Mary_ desires me to present her regards to you"--this was worth all the letter besides to the young duke; 'twas this he read over and over again, and forgot his estates and his debts, while his heart was reeling with gratitude for just this little kindness from _her_ whom he loved so devotedly. With woman, letter writing is in complete unison with her condition in society. The details of most interest to her correspondents are precisely those with which she is most conversant. She presents no mutilated picture; she gives that which delights. She is apt to know, too, the little Goshen of our hearts, and to pay all due attention to it. And she is sure to tell, as if by accident, precisely the _sweetest_ things in the world to _us_. She writes with ease, variety, and interest--because she pursues the course of the celebrated Madame de Sévigné, (who has never perhaps had an equal in our sex for epistolary composition.) "Il faut un peu entre bons amis," says Madame de S. "laisser trotter les plumes comme elles veulent, la mienne a toujours la bride sur le cou." I had intended, before concluding my remarks on the intellectual differences of the sexes, to offer some considerations in favor of improving the system of female education; but my number has already expanded to a size greatly beyond my anticipations when I commenced it. This subject I must therefore postpone for the present, and resume it in my next, if my time and occupations will permit me. For the Southern Literary Messenger. TO F----. And could'st thou F---- then believe That I had thought thy guileless heart Would prompt thee meanly to deceive, And stoop to play a treacherous part? No, lady no!--I saw thee move, Artless in unsuspecting youth; That heart I saw had learn'd to love The hallowed sanctity of _truth_.
