How he could ever have been content to remain a simple clerk all these years, Livingstone could not understand.

It gave him a certain contempt for him.

That came, he reflected, of a man's marrying indiscreetly and having a houseful of children on his back.
Clark would be pleased at the showing on the books.

He was always delighted when the balances showed a marked increase.
Livingstone was glad now that he had not only paid the old clerk extra for his night-work last year, but had given him fifty dollars additional, partly because of the trouble in his family, and partly because Livingstone had been unusually irritated when Clark got the two accounts confused.
Livingstone prided himself on his manner to his employees.

He prided himself on being a gentleman, and it was a mark of a gentleman always to treat subordinates with civility.
