two o'clock
There was n't anything more I could do except wait and try to keep that crazy heart of mine a little quiet . I knew that whenever or however they came they would be most likely to come in on the grade , so I thought the best place to wait was in Townsend 's store , as they would have to come up facing the back of it . The windows were planked up ; but I knew that there were no windows in town , or even sides of houses , either , which would stop a bullet from a good rifle . I calculated if they came in the night it would probably be about one or two o'clock , and if they waited till morning I could look for them when it began to get light . I went over to Townsend 's early in the evening and sat down close to a back window in the second story . I had Kaiser with me . I think he was gradually getting the thing through his head , because he had stopped wagging his tail and begun to growl once in a while .
