Books of travel, if they are expected to live, are peculiarly hard to write.  If they come out at a period when curiosity about the region described is predominant, they are fairly certain, no matter how wretched, to achieve temporary success.  But there is no kind of literary production to which, by the very law of its being, it is more difficult to impart vitality.  Paradoxical as it may seem, it is perfectly true that the greatest hinderance to their permanent interest is the information they furnish.  The more full, specific and even accurate that is, the more rapidly does the work containing it lose its value.  The fresher knowledge conveyed by a new, and it may be much inferior book, crowds out of circulation those which have gone before.  The changed or changing conditions in the region traversed renders the information previously furnished out of date and even misleading.  Hence the older works come in time to have only an antiquarian interest.  Their pages are consulted only by that very limited number of persons who are anxious to learn what has been and view with stolid indifference what actually is.  Something of this transitory nature belongs to all sketches of travel.  It is the one great reason why so very few of the countless number of such works, written, and sometimes written by men of highest ability, are hardly heard of a few years after publication.  Travels form a species of literary production in which great classics are exceedingly rare.

From this fatal characteristic, threatening the enduring life of such works, most of Warner’s writings of this sort were saved by the method of procedure he followed.  He made it his main object not to give facts but impressions.  All details of exact information, everything calculated to gratify the statistical mind or to quench the thirst of the seeker for purely useful information, he was careful, whether consciously or unconsciously, to banish from those volumes of his in which he followed his own bent and felt himself under no obligation to say anything but what he chose.  Hence these books are mainly a record of views of men and manners made by an acute observer on the spot, and put down at the moment when the impression created was most vivid, not deferred till familiarity had dulled the sense of it or custom had caused it to be disregarded.  Take as an illustration the little book entitled “Baddeck,” one of the slightest of his productions in this field.  It purports to be and is nothing more than an account of a two weeks’ tour made to a Cape Breton locality in company with the delightful companion to whom it was dedicated.  You take it up with the notion that you are going to acquire information about the whole country journeyed over, you are beguiled at times with the fancy that you are getting it.  In the best sense it may be said that you do get it; for it is the general impression of the various scenes through which the expedition leads the travelers that is left upon the mind, not those accurate details of a single one of them which the lapse of a year might render inaccurate.  It is to the credit of the work therefore than one gains from it little specific knowledge.  In its place are the reflections both wise and witty upon life, upon the characters of the men that are met, upon the nature of the sights that are seen.
