Argo Navis
Miss Jummy began her three-year-old season in The Riddlesworth over the Ditch Mile course at the Newmarket Craven meeting in mid-April. She led from the start and won by half a length from her only opponent, a colt named Oberon. On 30 April, Miss Jummy started at odds of 3/1 for in the 1000 Guineas over Newmarket's Rowley Mile course. The field of nine included her former opponents Modwena (the 2/1 favourite), Sunrise and Argo Navis. When the race began the outsider Sagitta rushed to the front and opened up a lead of twenty lengths before tiring rapidly after half distance. As Sagitta dropped back, Watts took over the lead on Miss Jummy just ahead of Cataract, Argo Navis and Modwena. Miss Jummy increased her advantage in the final furlong and comfortably held the challenge of Argo Navis to win the £3,250 prize by one and a half lengths; Jewel Song finished a head in front of Modwena to take third place.
