about four o'clock
`` Introducing the Jones family '' was one of them . In the afternoon Mr. von Inwald came out to the spring-house and sat around , very affable and friendly , drinking the water . He and the bishop grew quite chummy . Miss Patty was not there , but about four o'clock Mr. Pierce came out . He did not sit down , but wandered around the room , not talking to anybody , but staring , whenever he could , at the prince . Once I caught Mr. von Inwald 's eyes fixed on him , as if he might have seen him before . After a while Mr. Pierce sat down in a corner like a sulky child and filled his pipe , and as nobody noticed him except to complain about the pipe , which he did n't even hear , he sat there for a half-hour , bent forward , with his pipe clenched in his teeth , and never took his eyes off Mr. von Inwald 's face .
