“The Orkney Herald” of 8/11/1893 reports a ten foot diameter chamber, originally in the region of seven feet high, composed of masonry and stone pillars supporting a heavily flagstoned roof (the main slab of two feet thickness). The floor comprised two courses of masonry. It was approached by a paved passage 10’6” x 2’6” x 2’6”. There is no mention of contents in the Orkney Natural History Society paper as published in the newspaper.
The discovery report in “The Orkney Herald” of 4/3/1891 says the passage was half-way up the east side of the mond, and that two depressions on the top could mark lateral chambers.
Research by the man who was Tommy found an archaeological report of the time in the preceedings of an Irish journal
And still Nick Card, in a lecture May 24th 2013, repeats the canard that this mound had always been thought a natural mound until his lot did the geophysics - sometimes we Modern Antiqurians and Portalists despair !
