SciKpi- Siov, (lahri/dioii, dim. of S&Kpv, (hilri/, tear; re- ferring to the drops of giim exuded by the tree). A genus of lofty trees of the natural order Taxacea;, which has the male and the female flowers on separate individuals. The species are chiefly natives of Australia and New Zealand. Daert/dium Franlclinii is called Huon pine, al- though rather a yew than a pine. Its timber is harder than any Baltic pine, and is excellent for spars for naval jjurposes. The tree attains a height of a hundred feet, and a diameter of six feet. The wood is light, tough, and very durable. It is said to be one of the best Australian woods for carving. Dacrydium ctipressinum and Dacry- dium Kirkii are two species occurring in New Zealand, where they are large trees of considera- ble economic value. The drupes of both species are edible. The young twigs of Dacrydium cu- pressinum aro sometimes used for making a kind of beer. Closely i-elated are the species of Podo- carpus, of which there are a score or more species in Asia and through the islands of Australia. Podocarptis totara is the most valuable timber- tree of New Zealand, where it attains a height of 60 to 100 feet and a diameter of G to 8 feet. The bark is extensively used for roofing houses. Po- docarptis spicata and Podocarp'.is exoelsa are other species of value. DACTYIj (Lat. dacfylns, Gk. 5cJ<cti/Xos, dak- tylos, finger). The name of a measure or 'foot' in Greek and Latin versification. It consists of one long and two short syllables, as in the word ommhns, and was so called from its resemblance to the finger, which consists of three joints — one long and two short. The same name is applied to a trisyllabic measure in English verse, consist- ing of one accented syllable and two unaccented syllables, as in destiny. (See Versification.) Vol. V.-47. Dactylic verses consist of dactyrs and equivalent feet. See Hexasieter. DAC'TYLIS. See Okciiakd Grass. DAC'TYLOL'OGY (from Gk.

They were the discov- erers of copper and iron, and were deei)ly versed in the metal-w-orking arts. The legends later transferred them to the Cretan Jlount Ida, and identified them with the C'oryl)antes. They were originally three in luimber — Kclmis, the Smelter; Dainnameneus, the Hammer; and Acmon, the Anvil; then were increased to five, ten, fifty-two, and at last one hundred.

(1) In the United States, the long-legged, s]iidcr-like creatures of the arachnid family Plialangiida (See Har- VESTSIAN.) (2) In England, the files of the fam- ily Tipulidoe, which includes the crane-flies — big, long-legged insects, resembling exaggerated mos- quitoes, that swarm in late sinnmcr in grassy and bushy places. The eggs are not known. The larv;c of some live in damp earth, decaying wood, etc., and of others in the water, feeding on vege- table material, diatoms, etc. One curious wing- less genus (Chionea) contains the 'snow-inseets' occasionallj' seen in swarms on the surface of snowbanks. Some of the earth-inhabiting forms injure the roots of grain and other grasses. ]More than a thousand species have been de- scribed. DA 'DO (It, a die). In architecture, the term applied to the cubic block which forms the body of a pedestal. It is also applied to the plane face and the series of moldings which, in the interiors of buildings, form, as it were, a continuous pedestal. The ordinary modern in- terior dado is formed of wood, and, running round the bottom of the walls of a room, serves to iJrotect the plaster or pa]ier from injury. It is generally about three feet in height, and sur- mounted by a narrow cornice. It is also called a wainscot, though this name is more properly applied to a paneled dado.

The mythi- cal seul])tor. placed by Greek legend at the begin- ning of native art. to whom were attributed many early wooden statues, apparently of the type of the early nude male figures, such as the "Apollo of Orchomenos." The early forms of the legend seem to have made him a native of Crete, and there seems to have lieen an early school of Cretan artists, the Da'dalid.T. who claimed him as their ancestor.
