TOO often-it is a half-acknowledged delusion, however-one meets with what appears to be a theory: that a book of travel must necessarily be a series of dull, discursive, and entirely uncorroborated opinions of one who may not be even an intelligent observer. This is mere intellectual pretence. Even a humble author-so long as he be an honest one-may well be allowed to claim with Mr. Howells the right to be serious, or the reverse, "with his material as he finds it;" and that "something personally experienced can only be realized on the spot where it was lived." This, says he, is "the prime use of travel, and the attempt to create the reader a partner in the enterprise" ... must be the excuse, then, for putting one's observations on paper. He rightly says, too, that nothing of perilous adventure is to-day any more like to happen "in Florence than in Fitchburg." A "literary tour," a "cathedral tour," or an "architectural tour," requires a formula wherein the author must be wary of making questionable estimates; but he may, with regard to generalities, -or details, for that matter, -state his opinion plainly; but he should state also his reasons. With respect to church architecture no average reader, any more than the average observer, willingly enters the arena of intellectual combat, but rather is satisfied-as he should be, unless he is a Freeman, a Gonse, or a Corroyer-with an ampler radius which shall command even a juster, though no less truthful, view.
