Two or three other girls were walking down the corridor to the lecture-room ; the door was flung open . `` Very well , '' she said as she entered the room , followed by Rosalind , `` I will go with you .

'' Prissie nodded , seated herself at the lecture-table and in the interest of the work which lay before her soon forgot all about Rosalind and her troubles .
