"There are three cities readily accessible to the tourist, which are peculiar, - Quebec, New Orleans, and Pittsburg, - and of these Pittsburg is the most interesting by far. In other towns the traveler can make up his list of lions, do them in a few hours, and go away satisfied; but here all is curious or wonderful, - site, environs, history, geology, business, aspect, atmosphere, customs, everything. Pittsburg is a place to read up for, to unpack your trunk and settle down at, to make excursions from, and to study as you would study a group of sciences. To know Pittsburg thoroughly is a liberal education in "the kind of culture demanded by modern times.""
