Four o'clock
`` Midnight Mass ! Oh , I have never been to Midnight Mass. . It must be lovely . Four o'clock Mass was the earliest at our church , and Mother and Father and Uncle Frank and I went . It was pitch dark , and the stars were shining , and the snow was so nice and crunchy . That reminds me . We must do all we can this afternoon , Sister , because Uncle is going to take us for a long sleigh ride to-morrow . ''
