"The question of a separate intelligence having had due consideration, experiments were tried with regard to the sounds. The mediums, by request, moved to various portions of the room; and the sounds were produced, varying in quality according to the different substances from which they apparently proceeded. The 'toe-joint' theory being suggested by some one, the mediums were requested to stand on the spring cushion of a sofa. This they did, and merely touching the tip of a finger against the plastering, the sounds were distinctly and abundantly heard on, or rather _in_ the wall. They were equally distinct to a person in the adjoining room. That the ladies had no other contact with the wall than to touch it lightly with the tip of a single finger, all present can testify." Nor was this action of the members of the Press the only investigation by high authority which we two (Katie and I) underwent on this occasion of our visit to Boston, in 1857. It was proposed by our friends that we should meet a party of Unitarian clergymen at the house of Rev. Dr. Harrington, in Summerville, about six miles from Boston. They made a most thorough investigation. They held a consultation in a private room, and considered that now was the time to satisfy themselves in regard to the production of the sounds; as they had read the statement made by the Buffalo doctors, in which "knee-knocking" figures, and also the Burr toe-ological humbug, and many more wise theories, which they wished to prove true or silence forever. Rev. Dr. Francis, a brother of Lydia Maria Child, and another distinguished clergyman, were appointed to hold our knees, and two ladies held our feet, rested on chairs, exposed plainly to view. During the time we were held in this position, sounds were made all around the room--on chairs, on the floor, under their feet, etc. One old gentleman shouted out, "Thank God, I always believed the raps were genuine, and now I know they are." He then told us he was living near Rochester when we first came before the public, and always felt the deepest sympathy for us. At the close of the investigation we were all invited to go into the dining-room, where a sumptuous banquet had been prepared for the party. The Spirits of earth and heaven met and rejoiced together on this occasion; and there were many more of the invisible ones than of those still in the flesh. Many sweet songs were sung, and the timely echoes from the Spirit world told us plainly that they were not afar off. It was time for us to leave them. Mr. Alvin Adams had taken us there in his beautiful equipage, and he advised us of the hour. The party accompanied us to the carriage, and with many blessings and words of encouragement, bid us farewell.
