A riddle in which names of towns, persons, rivers, &c., are hidden or arranged, without transposition, in the midst of sentences which convey no suggestion of their presence. In the following sentence, for instance, there are hidden six Christian names:--Here is hid a name the people of Pisa acknowledge: work at each word, for there are worse things than to give the last shilling for bottled wine.--The names are Ida, Isaac, Kate, Seth, Ethel, Edwin. Great varieties of riddles, known as Buried Cities, Hidden Towns, &c., are formed on this principle, the words being sometimes placed so as to read backwards, or from right to left. The example given will, however, sufficiently explain the mode of operation.
