McCosh, to decide intelligibly upon the issue raised. Then I fell into a long and abstruse calculation with my landlord; having for object to compare the distance driven by him during eight years’ service on the box of the Wendover coach with the girth of the round world itself. We tackled the question most conscientiously, made all necessary allowance for Sundays and leap-years, and were just coming to a triumphant conclusion of our labours when we were stayed by a small lacuna in my information. I did not know the circumference of the earth. The landlord knew it, to be sure⁠—plainly he had made the same calculation twice and once before⁠—but he wanted confidence in his own figures, and from the moment I showed myself so poor a second seemed to lose all interest in the result.
