A sequel to Monday's balloon-bursting episode in Lowell House was provided yesterday when a chubby hydrogen filled blimp soared to the ceiling during dinner. Resourceful Bellboys, undismayed by the situation, reached up and grasped a string hanging from the runaway and pulled it to earth, not before, however, a prankster held a lighted match to the balloon's capacious belly. Members of the House were startled to see a large orange flame a la Hindenburg appear in mid-air accompanied by a small peal of thunder.
