But it is not always practicable, even to the most stalwart and seasoned passenger, to spend his time on the open deck. To stand out on the front (one can hardly call it a prow, where the periphery is that of an average wash-tub) or at the stern is to be drowned by rain or sawn asunder by icy winds or broiled like an oyster, and to cower under the upper deck is to get a lively sense of the Cave of the Winds. One with a healthy sense of smell and an instinct for oxygen may well shrink from entering the cabin, and prefer the perils and discomforts of too much atmosphere to those of a depleted and poisoned one. David may have been wise in choosing to be punished for his sins by pestilence rather than by famine or the sword, but he put it on very doubtful ground when he thought he was thereby falling into "the hand of the Lord" in some special manner. For I am confident that bad air is the devil, and that it is this "power of the air" of which he is "prince." And he has no more impregnable stronghold than the cabin of a ferry-boat in winter. In the cars one can brave public opinion and elude the brakeman's eye so as to open something in his "Black Hole." But the cabin windows are hermetically sealed and the doors jealously guarded by an unsleeping dragon. On some of these boats they have an ingenious method of intensifying the sickening odor by anointing the floors with a rancid oil, which affords the tender stomach all the advantages of the famous crossing of the English Channel. The entire code of the cabin is still to be rescued from the civilization of the cave-dwellers. The essence of politeness has been shown to be self-sacrifice in small things. The average American is naturally as unselfish a being as dwells upon the planet, but he often appears to disadvantage beside far meaner races by reason of an insane haste which tramples politeness under its feet. "After you, sir,"--a phrase which contains in a nutshell the very kernel of all courtesy,--puts the thing in a shape which is almost a physical impossibility to the American temperament. Our fellow-citizen will go ahead of you with the utmost gallantry, though it be to storm a Malakoff or grapple with a mad dog; but to stand aside and let you get on or off a ferry-boat before him is a strain upon his manners enough to dislocate their every limb. Well, remembering that the passive mood comes after the active in grammatical sequence, we will not despair of a development of the passive virtues even in the "go-ahead" American. And then the law of the cabin will no longer be mob-law, nor its motto, "Every man for himself, and ---- take the ladies."
