Formerly, the genus was so defined as to include nearly or quite 30 species. The well-known D. draco, or dragon-tree, requires to be studied in its native country, the Canary Islands. Commencing as an unbranched endogen with linear entire evergreen sheathing leaves, which leave annular scars as they fall annually, it continues to advance slowly to maturity, the process, it is said, taking 25 to 30 years. Then the leaf scars are gradually obliterated, and branches begin to be put forth. Next a glorious panicle of inflorescence appears at the apex of the stem, the individual flowers of which, however, are small and greenish white. At an indefinitely long period it begins to decay. The celebrated dragon-tree of Teneriffe was one of the wonders of the world. Bethencourt in 1402 or 1406 described it as old and hollow. It had changed but little from that time till its destruction in 1867. It was between 70 and 75 feet high, with a circumference at the base of about 462 feet. D. draco furnishes one of the resins called dragon's-blood. The tree called D.

Sir Arthur Conan, an English novelist. He was born in Edinburgh, Scotland, in 1859. He was educated at a Roman Catholic college in Lancashire, and at the University of Edinburgh. He practiced as a physician for a time, but having published several successful stories, he gave over the profession of medicine for literature. Among his best known stories are Micah Clarke, A Study in Scarlet, The Hound of the Baskervilles, The White Company. Doyle is most noted, however, for his creation of the character of Sherlock Holmes. The Adventures of Sherlock Holmes are a series of detective stories which have been extremely popular. Holmes is represented as an amateur detective of great skill. By scientific knowledge and methods of reasoning, he makes use of the most inconsequential facts to discover remote and surprising causes. He is a cocaine fiend, and is very eccentric, but, withal, so real an individual that his personality makes a lasting impression upon the reader. Aside from the twelve tales in The Adventures of Sherlock Holmes, the character of Holmes appears in many other stories, especially in a series entitled The Return of Sherlock Holmes. Doyle was knighted in 1902.
