I have engaged passage on the _Cambria_ for St. Louis, and am now impatient to be off. The boat was to start at 4 o'clock P. M., but we are yet here. It is a very common practice of deceiving travelers as to the time of the departure of boats. It should be frowned down by the traveling public, as it causes great perplexity and loss of time, etc. Passengers are still coming on board. Most of them are bound for California. A large number of mules and horses are on deck. Some of them are inferior animals, especially the mules. The price of mules and horses is represented as being quite high at St. Joseph and Independence. Good wagons can be purchased here for $75.00, and many are being taken for the emigrating service. A company has been organized here, offering to carry passengers to the gold region for $160, each passenger to do his equal share of the necessary labor upon the road. APRIL 5, 1850. Ohio River, April 5, 1850. We left Cincinnati yesterday afternoon about 5 o'clock, with a large number of passengers on board. Reached Madison last night and laid to till morning. We are now riding along at a fine rate. The clouds that hung above us all the morning are partly cleared away, and the warm sun shining through at intervals, making it rather pleasant and it would be really so, were it not for a cold breeze that is now up. The trees upon the banks of the river begin to assume the appearance of spring, putting forth their fresh buds and lending to the prospect some degree of cheerfulness. The banks of the river are here high and abrupt, and well timbered, though the general prospect is rather monotonous. SUNDAY, APRIL 7. I made no note of yesterday, having seen nothing of particular interest. The river banks become lower as we descend. Today I have seen fruit trees in blossom. Our passage is rather disagreeable--too cool to be agreeable on deck, from which the passenger wishes to view the shores of the river. I rose early this morning and went on deck, as usual. It was early dawn, so early that I would not have thought it morning were it not for a golden streak in the east, glowing beneath a heavy mass of dark clouds. We were just then at an interesting point, passing round the point from the Ohio into the mighty Mississippi, and had already begun to stem its muddy current when I came on deck. I took a long look down between her banks, for the purpose of impressing upon my memory a picture which I might unveil in the future. The flush of crimson dawn-light was reflected upon the ripples that came chasing in our wake.
