In a letter of 23 August 1924, Wallace writes that he is going to Mammoth Cave to participate in experiments regarding "the directional transmission of wireless waves. They think they have run across a new theory about the ability of the radio waves to penetrate under the earth's surface, and are going to set up an instrument inside the cave and see what effect the position in relation to the broadcasting station has over the reception of signals."
