----Travel, according to my experience, does not exactly correspond to the idea one gets of it out of most books of travels. I am thinking of travel as it was when I made the Grand Tour, especially in Italy. Memory is a net; one finds it full of fish when he takes it from the brook; but a dozen miles of water have run through it without sticking. I can prove some facts about travelling by a story or two. There are certain principles to be assumed,--such as these:--He who is carried by horses must deal with rogues.--To-day's dinner subtends a larger visual angle than yesterday's revolution. A mote in my eye is bigger to me than the biggest of Dr. Gould's private planets.--Every traveller is a self-taught entomologist.--Old jokes are dynamometers of mental tension; an old joke tells better among friends travelling than at home,--which shows that their minds are in a state of diminished, rather than increased vitality. There was a story about "strahps to your pahnts," which was vastly funny to us fellows--on the road from Milan to Venice.--_Coelum, non animum_,--travellers change their guineas, but not their characters. The bore is the same, eating dates under the cedars of Lebanon, as over a plate of baked beans in Beacon Street.--Parties of travellers have a morbid instinct for "establishing raws" upon each other.--A man shall sit down with his friend at the foot of the Great Pyramid and they will take up the question they had been talking about under "the great elm," and forget all about Egypt. When I was crossing the Po, we were all fighting about the propriety of one fellow's telling another that his argument was _absurd_; one maintaining it to be a perfectly admissible logical term, as proved by the phrase, "reductio ad absurdum"; the rest badgering him as a conversational bully. Mighty little we troubled ourselves for _Padus_, the Po, "a river broader and more rapid than the Rhone," and the times when Hannibal led his grim Africans to its banks, and his elephants thrust their trunks into the yellow waters over which that pendulum ferry-boat was swinging back and forward every ten minutes! ----Here are some of those reminiscences, with morals prefixed, or annexed, or implied. Lively emotions very commonly do not strike us full in front, but obliquely from the side; a scene or incident in _undress_ often affects more than one in full costume. "Is this the mighty ocean?--is this all?" says the Princess in Gebir. The rush that should have flooded my soul in the Coliseum did not come. But walking one day in the fields about the city, I stumbled over a fragment of broken masonry, and lo! the World's Mistress in her stone girdle--_alta maenia Romae_--rose before me and whitened my cheek with her pale shadow as never before or since.
