The junior varsity football team added number four to its string of victories yesterday, edging by a strong Dartmouth squad, 7 to 0, in the final moments of play.

Crimson quarterback Grady Watts scored the winning touchdown on an 11-yard rollout-option run run around right end late in the fourth quarter. Halfback Bob Hunter successfully toed the conversion.

Watts' score came as a crowning conclusion to an impressive 60-yard Crimson drive sparked by a 25-yard jaunt around right and by fleet-footed sophomore half-back Harris Leroy.

Dartmouth caused concern for Crimson fans only once. At the end of the first quarter the Indians, on their own 35, clicked with a 25 yard pass to put the ball on the Crimson 40. Moving slowly but steadily, Dartmouth then pushed on up to Harvard's nine yard line. But that was all, as the Crimson took over on downs.

Outstanding in the Crimson attack was the work of junior fullback Gill Bamford, who reeled off hard-driving runs regularly all afternoon. Left guard Dick Baker drew praises from observers for his work in the line.

With a 4-0 record to date, coach Norm Shepard's eleven next faces Penn.
