three
o'clock
I do n't think I ever worked so hard in my life as I did at that job . It was not very cold , which was one good thing . Every minute I expected the wolves , and I did not have long to wait either . Before three o'clock they came howling along the trail the buffaloes had made , and I had to stop and fire at them every few minutes to keep them off . I am sure they were not so hungry as usual or I never could have kept them back at all . Twice I killed one when I shot , but I dared not go up and get them , and they were soon devoured by the others . The pack kept growing larger as others came over from the timber north of the Butte .
