_Chicago, Nov. 10th._--We did not reach Chicago last night till 12 o'clock, our train, for the first time since we have been in America, having failed to reach its destination at the proper time; but the delay of two hours on this occasion was fairly accounted for by the bad state of the rails, owing to the late rains. Before it became dark we saw one or two wonderful specimens of towns growing up in this wilderness of prairie. The houses, always of wood and painted white, are neat, clean, and well-built. There is, generally, a good-looking hotel, and invariably a church, and often several of these, for although one would probably contain all the inhabitants, yet they are usually of many denominations, and then each one has its own church. About twenty or thirty miles from Chicago, we saw a very extensive tract of prairie on fire, which quite illuminated the sky, and, as the night was very dark, showed distinctly the distant trees and houses, clearly defining their outline against the horizon. On the other side of us, there was a smaller fire, but so close as to allow us to see the flames travelling along the surface of the ground. These fires are very common; we saw no less than five that night in the course of our journey. We have been busily employed to-day in going over Chicago. The streets are wide and fine, but partake too abundantly of prairie mud to make walking agreeable: some of the shops are very large; a bookseller's shop, to which papa and I made our way, professes to be the largest in the world, and it is certainly one of the best supplied I ever saw with all kinds of children's books. From the bookseller's we went to papa's bankers, Messrs. Swift and Co.; Mr. Swift took us to the top of the Court-house, a wonderful achievement for me, but well worth the trouble, as the view of the town was very surprising. We went afterwards to call on William's friend, Mr. Wilkins, the consul, where we met Lord Radstock. Mr. Wilkins kindly took us to see Mr. Sturge's great granary; there are several of these in the town, but this, and a neighbouring one, capable of holding between them four or five million bushels of corn, are the two largest. The grain is brought into the warehouse, without leaving the railway, the rails running into the building. It is then carried to the top of the warehouse "in bulk," by means of hollow cylinders arranged on an endless chain. The warehouse is built by the side of the river, so that the vessels which are to carry the corn to England or elsewhere, come close under the walls, and the grain is discharged into the vessels by means of large wooden pipes or troughs, through which it is shot at once into the hold. Mr. Wilkins has seen 80,000 bushels discharged in this manner, in one day.
