At the time of the first explosion about a dozen loafing Numbers from the docks stood near the main tube⁠—and nothing was left of them save a few crumbs and a little soot. With pride I write down now that this occurrence did not disturb the rhythm of our work even for a second. Not a man shrank.

A dozen Numbers represent hardly one hundred millionth part of the United State. For practical consideration, that is but an infinitesimal of the third order. That pity , a result of arithmetical ignorance, was known to the ancients; to us it seems absurd.
