Queen Sheba's Ring

Every one has read the monograph, I believe that is the right word, of my dear friend, Professor Higgs - Ptolemy Higgs to give him his full name - descriptive of the tableland of Mur in North Central Africa, of the ancient underground city in the mountains which surrounded it, and of the strange tribe of Abyssinian Jews, or rather their mixed descendants, by whom it is, or was, inhabited. I say every one advisedly, for although the public which studies such works is usually select, that which will take an interest in them, if the character of a learned and pugnacious personage is concerned, is very wide indeed. Not to mince matters, I may as well explain what I mean at once.
