Chicago is truly an interesting place. It has sprung up here in three or four years--a city--as by the wand of enchantment. I had heard much of this place, but must confess I was not prepared to find so large and interesting a town. Its situation on either side of the Chicago river is too well-known to need description. It has quite the air of an eastern town. There is a fine brick Episcopal Church just completed. Our stay was very brief in Chicago. Almost the first sound we heard after our arrival, was the ringing of the bell of the large and beautiful steamboat, _James Madison_, which was on the eve of departure for Detroit and Buffalo. As we might have no other opportunity of going by the lakes for the next ten days, with the specimen of land travelling that we had just had, we were not long in making up our minds whether we would avail ourselves of this boat, or direct our course to Detroit through the Michigan woods. We gave Chicago a very hasty survey, took our passage on board the James Madison, and as the shades of evening gathered over us we found ourselves skimming over the waves of Michigan lake. _Mackinaw, July 20th._ We this morning found ourselves bounding over the green waters of the Michigan with the Wisconsin Territory on our left. About nine o'clock, A. M. we landed at Milwaukie. A bar in the river prevented the steamboat from going up to the town, but we found ourselves amply compensated for our long walk by a view of this interesting place from several of its streets and more elevated parts. The whole site of the town, in connexion with the adjacent country, is richly entitled to its Indian name,--"THE LOVELY LAND." Less than two years since there was scarcely a frame house on the spot, and now there is a population of nearly three thousand, with buildings that will compare in stability and elegance with those found in our large eastern towns.
