_Sept, 15th._--In a letter to my brother George, to-day, I said:--It would be superfluous for me to tell you that the letter I received from you gave me unspeakable pleasure. Your fears with respect to my injuring my health are groundless, for I must confess I don't possess half that application and burning zeal in these all-important pursuits that I ought to have. For who can estimate the value of a liberal education? Who can sufficiently prize that in which all the powers of the human mind can expand to their utmost and astonishing extent? What industry can outstretch the worth of that knowledge, by which we can travel back to the remotest ages, and live the lives of all antiquity? Nay, who can set bounds to the value of those attainments, by which we can, as it were, fly from world to world, and gaze on all the glories of creation; by which we can glide down the stream of time, and penetrate the unorganized regions of uncreated futurity? My heart burns while I write. Although literature presents the highest objects of ambition to the most refined mind, yet I consider health, in comparison with other temporal enjoyments, the most bountiful, and highest gift of heaven.
I have read three books of the Georgics, and three odes of Horace, but this last week I have read scarcely any, as I have had a great deal of company, and there has been no school. But I commence again to-day with all my might. The Attorney-General stops at Mr. Aikman's during Court. I find him very agreeable. He conversed with me more than an hour last night, in the most sociable, open manner possible.
_Sept. 16th._--There is nothing of greater importance than to commence early to form our characters and regulate our conduct. Observation daily proves that man's condition in this world is generally the result of his own conduct. When we come to maturity, we perceive there is a right and a wrong in the actions of men; many who possess the same hereditary advantages, are not equally prosperous in life; some by virtuous conduct rise to respectability, honour, and happiness; while others by mean and vicious actions, forfeit the advantages of their birth, and sink into ignominy and disgrace. How necessary that in early life useful habits should be formed, and turbulent passions restrained, so that when manhood and old age come, the mind be not enervated by the follies and vices of youth, but, supported and strengthened by the Divine Being, be enabled to say, "O God, thou hast taught me from my youth, and now when I am old and grey-headed, O God, thou wilt not forsake me!"
