To avoid this difficulty, therefore, the only remedy which could be found would consist in the employment of some great natural boundary, such as a range of mountains or an expanse of water, by which those on one side of the day-line would be so separated as to prevent the disorder which must arise from constant and uninterrupted intercommunication. That there is any range of mountains stretching northward and southward from pole to pole which would answer the purpose in question, no one will insist. The only resource left, consequently, is that of those vast bodies of water called seas or oceans. Turning now to the one which is known as the Atlantic Ocean, it is found that the day-line could not be run through it without intercepting some habitable portion of the globe. The only resource which remains is found in the Pacific Ocean, which, as has been seen, has been selected by the mass of mankind as a suitable place in which to make those changes that would be necessary in case the day-line was actually located therein. Happily, an examination of a large globe will prove that a line drawn from Behring’s Straits southward across the latitudes which are available for the homes of mankind will not touch any portions of land whatever, or at least if it strikes any they would be so insignificant in their character that they would not be worthy of mention. With these remarks, the subject of the day-line is dismissed with the conviction that the necessity of its existence, the fact that it must be found in the Pacific Ocean if anywhere, and the uniform recognition in practice, if not in theory, by all nations, of its location in that sea, unite in furnishing a combination of facts which render assurance justifiable in the mind of one who does not insist upon more testimony than he ought to demand. There remain now but two matters in the article of the gentleman which need to be disposed of. These are found in the contemptuous sneer at the insignificance of the numbers of Sabbatarians, and the witticisms, if such they may be called, which are indulged in in the employment of the suggestion concerning the use of the sponges saturated with stupefying chemicals and the gratuitous trip around the world, which it is proposed to give them.
