The card told more tales than the words written on it. Its colour indicated the nation of the stranger. Yellow showed him to be English; red, Spanish; white, Portuguese; green, Dutch; red and white, Italian; red and green, Swiss; green and white, Russian; etc. The person’s age was expressed by the shape of the card. If it were circular, he was under 25; oval, between 25 and 30; octagonal, between 30 and 45; hexagonal, between 45 and 50; square, between 50 and 60; and oblong showed that he was over 60. Two lines placed below the name of the bearer indicated his build. If he were tall and lean, the lines were waving and parallel; tall and stout, they converged; and so on. The expression of his face was shown by a flower in the border. A rose designated an open and amiable countenance, whilst a tulip marked a pensive and aristocratic appearance. A fillet round the border, according to its length, told whether the man was bachelor, married, or widower. Dots gave information as to his position and fortune. A full stop after his name showed that he was a Catholic; a semicolon, that he was a Lutheran; a comma, that he was a Calvinist; a dash, that he was a Jew; no stop indicated him as an Atheist. So also his morals and character were pointed out by a pattern in the angles of the card, such as one of these: [Illustration] Consequently, at one glance the minister could tell all about his man, whether he were a gamester or a duellist; what was his purpose in visiting France; whether in search of a wife or to claim a legacy; what was his profession--that of physician, lawyer, or man of letters; whether he were to be put under surveillance or allowed to go his way unmolested. We come now to a class of cypher which requires a certain amount of literary dexterity to conceal the clue. During the Great Rebellion, Sir John Trevanion, a distinguished Cavalier, was made prisoner, and locked up in Colchester Castle. Sir Charles Lucas and Sir George Lisle had just been made examples of, as a warning to “malignants”: and Trevanion has every reason for expecting a similar bloody end. As he awaits his doom, indulging in a hearty curse in round Cavalier terms at the canting, crop-eared scoundrels who hold him in durance vile, and muttering a wish that he had fallen, sword in hand, facing the foe, he is startled by the entrance of the gaoler who hands him a letter: “May’t do thee good,” growls the fellow; “it has been well looked to before it was permitted to come to thee.” Sir John takes the letter, and the gaoler leaves him his lamp by which to read it:
