A French naturalist, named Lacazo Duthiers, was on board a ship, when, one day, he saw a sailor marking his clothes and the sails of the ship with a sharp-pointed stick, which, every now and then, he dipped into a little shell held in his other hand. At first, the lines were only a faint yellow in color; but, after being a few minutes in the sun, they became greenish, then violet, and last of all, a bright, beautiful purple, the exact shade called by the ancients "Tyrian purple"--a color that never fades by washing, or exposure to heat or damp, but ever grows brighter and clearer! The naturalist was rejoiced, and after trial found that he really had discovered again the long-lost secret. He felt well repaid for keeping his eyes open. The little shell was the "wide-mouthed purpura," as some call it, some three inches long, found in the Mediterranean Sea, and on the coasts of France, Ireland and Great Britain. My book says that the difficulty of obtaining and preserving these shells must always render "Tyrian purple" a rare and expensive color.
I remember, too, that the Babylonians thought "Tyrian purple" too sacred for the use of mortals, so they used it only in the dress of their idols. Romulus, king of Rome, adopted it as the regal color, and the Roman emperors forbade any besides themselves to wear it, on penalty of death.--Yours truly, F. R. F.
The boys and girls who solved the poetical charade printed on page 639 of the July number, must have noticed that it is an unusually good one, and we are sure that all our readers will admire the charade, after comparing it with its solution, which we publish upon page 704 of this number.
DEAR ST. NICHOLAS: I should like to know who would succeed to the throne in case of Queen Victoria's and her eldest son's deaths. My brother and I sold hickory-nuts and onions to get the St. Nicholas last fall. We have taken it ever since it was published. I am ten years old.
Prince Albert Victor, the Prince of Wales's eldest son, if then alive, would succeed to the English throne after Queen Victoria, in case of the previous death of her eldest son,--the Prince of Wales. A general answer to this question will be found in the "Letter-Box" for May, 1877 (Vol. IV., page 509), in a reply to an inquiry from "Julia."
