about midnight
I heard Salmon Head tell Uncle he hoped it would be cold to-morrow night , and that we should start for the Pass about four or five o'clock in the afternoon . I wonder what he meant by that . '' `` I heard Captain Zoss speaking of it . They start toward evening so as to pass the deepest snows on the summit about midnight when a crust forms to walk on , for at this season of the year the deep snows are too soft to be trusted when the sun is shining . '' `` And what happens to a fellow , I wonder , if he breaks through the snow ? '' `` I do n't know , I 'm sure -- I guess he goes to kingdom come , '' and Randy shuddered again . `` We 'll know all about it by this time to-morrow night . ''
