Let it be understood that this Committee of ladies and gentlemen took us to the parlors of the Rochester House, which could be divided into two rooms by closing the folding-doors. After dinner the gentlemen of the Committee insulated the table by putting glass under the legs, procured two sacks of feathers, and advised the ladies how to conduct the investigation. They then closed the doors, and (the gentlemen of the Committee having retired) left us and the lady members of the Committee alone. By this time the Committee had become kindly disposed toward us. They suggested to us that we should stand upon the sacks of feathers on the table, with our dresses tied tight above our ankles. We complied with all their suggestions, cheerfully. Immediately the sounds were heard on the table, floor, and walls. The ladies instantly opened the doors, and the gentlemen came in and witnessed the manifestations themselves. The ladies, at my suggestion, signed the following certificate: "When they were standing on pillows, with a handkerchief tied around the bottom of their dresses, tight to their ankles, we all heard the rapping on the table, on the wall, and floor distinctly. "MRS. STONE. "MRS. J. GATES. "MISS M. P. LAWRENCE." Before we left the room, word was sent to the Committee, saying, "Do not go to the Hall this evening; for if you report favorably to the girls you will be mobbed." Our friends, who anticipated a riot and feared for our safety, as soon as we got to the house after this terrible day's work and anxiety, urged us not to go to the Hall. But what were we to do? Even the Committee were threatened if it made a favorable report; but they all informed us that they would protect us in any event.
