Gregory, declaring the whole story of the Cape diamond discovery to be “false,” “an imposture,” “a bubble scheme,” got up to promote the expenditure of capital in in searching for this precious substance in the colony; and stating that, from the geological character of the district which he had lately very carefully and thioroughly examined, it was impossible that diamonds had been or could ever be found there.
