Calderwell had met Mr. M. J. Arkwright in London through a common friend; since then they had tramped half over Europe together in a comradeship that was as delightful as it was unusual. As Calderwell put it in a letter to his sister, Belle: ''We smoke the same cigar and drink the same tea (he's just as much of an old woman on that subject as I am!), and we agree beautifully on all necessary points of living, from tipping to late sleeping in the morning; while as for politics and religion-we disagree in those just enough to lend spice to an otherwise tame existence.'' Farther along in this same letter Calderwell touched upon his new friend again.
