My best wishes, in the joys, and festivities, and the solemn services of that day on which will be completed the fiftieth year from its birth, of the independence of the United States: a memorable epoch in the annals of the human race, destined in future history to form the brightest or the blackest page, according to the use or the abuse of those political institutions by which they shall, in time to come, be shaped by the human mind.
