If you did, it′s time I woke you!” / This day there was for them no box overlooking the finish, no club-house luncheon. With the other <WSD>pikers</WSD>, they sat in the free seats, with those who sat coatless and tucked their handkerchiefs inside their collars, and those who mopped their perspiring countenances with rice-paper and marked their cards with a hat-pin. Their lunch consisted of a massive ham sandwich with a top dressing of mustard.
