Mr. T. kept his counsel, said nothing more, and the lamp has never failed since; but half the merit of this story depended on Mr. Tyson's way of telling it. He was deliciously graphic also, and full of witty sayings of his own. When, for example, I showed him my photograph of your little brother, he exclaimed, "Well, he _is_ a fine fellow; HE don't mind if corn is five dollars a bushel." I think you will all appreciate this as a perfect description of the unconcern of a healthy intelligent-looking child, unconscious of the anxieties of those about him; but I must reserve his other good sayings and stories till we meet. To-day we have been most busily employed, for Mr. Garrett, our railway friend at Baltimore, not only did us the good service of sending us by the car under Mr. Tyson's auspices, but gave us letters of introduction both to this place and to Cincinnati; and his letters here to Mr. Neil and Mr. Dennison have been of great use to us, as one or the other of them has been in attendance upon us since 11 o'clock this morning, together with a very pleasing person, a widow, niece of Mr. Neil, and they have shown us the town in first-rate style. Columbus is built on the banks of the Sciota, about 90 miles from the point where it falls into the Ohio. It is the capital of the State, and its streets, like those of Washington, have been laid out with a view to its becoming one day a town of importance; but as the preparations for this, though on a considerable scale, are not so great as at Washington, the non-completion of the plan in its full extent produces no disagreeable effect. In fact, the streets where finished are completely so, and the unfinished parts consist of an extension of these, in the shape of long avenues of trees. In the principal streets the houses are not continuous, but in detached villas, and, judging by the one in which Mr. Neil lives, appear to be very comfortable residences. He and his niece called upon us yesterday evening, and, although he is an elderly gentleman, he was here by appointment this morning at half-past 8, and took papa to call on Mr. Dennison, when they arranged together the programme for the day.
