_On board the Elk, Monday Evening, June 19._ I have two exceedingly agreeable travelling companions. The one, Mr. B----, who started with a special view of accompanying me in this tour. He is a young gentleman of mature intellect, accomplished education, and ardent piety. The other friend we fell in with on our way to Pittsburg. Mr. F---- is a merchant, residing in Boston, a devoted member of the Congregational Church, a man of business, and of sterling Christian principle, possessing more of "the milk of human kindness" than ordinarily falls to the lot of mortals. The presence of these delightful companions has taken away much of the solitariness one feels in having a space of so many miles thrown between him and his home. Whoever has travelled on any of the western rivers knows something about the annoyances connected with western steamboats--the drinking--the swearing--the gambling. We were induced to take our passage in "THE ELK," from the fact that it was the only boat that was going down the river this morning. We soon found that our boat was not of the first order; our captain, however, appears to be one of the most quiet, taciturn, and unmoveable men we ever met. It was about ten o'clock, that we found our boat pushing off from the shore, and our backs turned upon the clouds of smoke that hung in dense masses over what has been called the Birmingham of America. As we stood on the deck, we seemed at the moment of starting enclosed by a forest of dark tunnels peering up from countless steamers lying along the shore. More than forty of these were clustered together in the same group where "_The Elk_" was stationed. It is said there cannot be less than seven hundred steamboats moving on these western and south-western rivers.
