"It can," said George. "We know Holland and the Rhine. Very well, my suggestion is that we take the boat to Hamburg, see Berlin and Dresden, and work our way to the Schwarzwald, through Nuremberg and Stuttgart." "There are some pretty bits in Mesopotamia, so I've been told," murmured Harris. George said Mesopotamia was too much out of our way, but that the Berlin- Dresden route was quite practicable. For good or evil, he persuaded us into it. "The machines, I suppose," said George, "as before. Harris and I on the tandem, J.--" "I think not," interrupted Harris, firmly. "You and J. on the tandem, I on the single." "All the same to me," agreed George. "J. and I on the tandem, Harris--" "I do not mind taking my turn," I interrupted, "but I am not going to carry George _all_ the way; the burden should be divided." "Very well," agreed Harris, "we'll divide it. But it must be on the distinct understanding that he works." "That he what?" said George. "That he works," repeated Harris, firmly; "at all events, uphill." "Great Scott!" said George; "don't you want _any_ exercise?" There is always unpleasantness about this tandem. It is the theory of the man in front that the man behind does nothing; it is equally the theory of the man behind that he alone is the motive power, the man in front merely doing the puffing. The mystery will never be solved. It is annoying when Prudence is whispering to you on the one side not to overdo your strength and bring on heart disease; while Justice into the other ear is remarking, "Why should you do it all? This isn't a cab. He's not your passenger": to hear him grunt out: "What's the matter--lost your pedals?" Harris, in his early married days, made much trouble for himself on one occasion, owing to this impossibility of knowing what the person behind is doing. He was riding with his wife through Holland. The roads were stony, and the machine jumped a good deal. "Sit tight," said Harris, without turning his head. What Mrs. Harris thought he said was, "Jump off." Why she should have thought he said "Jump off," when he said "Sit tight," neither of them can explain. Mrs. Harris puts it in this way, "If you had said, 'Sit tight,' why should I have jumped off?" Harris puts it, "If I had wanted you to jump off, why should I have said 'Sit tight!'?" The bitterness is past, but they argue about the matter to this day.
