oars, relieved every hour; and we descended rapidly. Early on the morning
of the 10th, we halted to make some astronomical observations at the mouth
of the Kansas, exactly four months since we had left the trading-post of
Mr. Cyprian Chouteau, on the same river, ten miles above. On our descent
to this place, we had employed ourselves in surveying and sketching the
Missouri, making astronomical observations regularly at night and at mid-
day, whenever the weather permitted. These operations on the river were
continued until our arrival at the city of St. Louis, Missouri, on the
17th. At St. Louis, the sale of our remaining effects was made; and,
leaving that city by steamboat on the 18th, I had the honor to report to
you at the city of Washington on the 29th of October.

Very respectfully, sir,
Your obedient servant,
J. C. FREMONT,
_2d Lieutenant Corps of Topographical Engineers._
