Permit me to introduce to thee my youngest brother, Joseph Briggs, who is going with me to the Mississippi Territory, and whom I mean to employ as a clerk.

I enclose a copy of a letter which I wrote to thee from Philadelphia, lest the original should have miscarried.

I must have misunderstood Henry Voight, or he must have deceived himself, in the probable time when my Transit Instrument would be finished; as he advanced in the work, the period of its completion seemed to be removed to a distance far beyond my expectation. Upon his informing me that it would probably require several months to complete it, I immediately packed up the remainder of my outfit, and had it put into a waggon, which left Philadelphia, on the 12th. instant, for Pittsburg, where I intend to arrive as soon as it—I shall leave home on the 23rd. instant.

Henry Voight is to send my Portable Transit and a Chronometer, immediately when finished, by sea, to Natchez.

I saw Captain M. Lewis, in Philadelphia, on the 10th. & 11th. instants.

Permit me to repeat assurances of my esteem and respect, and that I am Thy friend,
