Circumambulator of the earth

This is from my letter to John Banister, Jr., June 19, 1787. It’s what you call today as a “Dad Joke”:

I had a letter from Ledyard lately, dated at St. Petersburg. He had but two shirts, and yet more shirts than shillings. Still he was determined to obtain the palm of being the first circumambulator of the earth. He says, that having no money, they kick him from place to place, and thus he expects to be kicked round the globe.
