EMBURY, Emma Catharine, an American au- thoress, born in New York in 1806, died in Brooklyn, N. Y., Feb. 10, 1863. She was the daughter of Dr. James R. Manley of New York, and was married to Mr. Daniel Embury in 1828. In the same year she published " Guido and other Poems." She frequently contributed to periodicals poems and tales, most of which afterward appeared in a collected form, under the titles of " The Blind Girl and other Tales," " Glimpses of Home Life," and "Pictures of Early Life." In 1845 she supplied the letter- press, both prose and verse, to an illustrated gift book entitled " Nature's Gems, or Amer- ican Wild Flowers," and in the succeeding year published a collection of poems called " Love's Token Flowers." In 1848 she pub- lished "The Waldorf Family, or Grandfather's Legends," a fairy tale of Brittany, partly a translation and partly original. EMBURY, Philip, the first Methodist minister in America, born in Ballygaran, Ireland, Sept. 21, 1729, died at Oamden, Washington co., N. Y., in August, 1775. He was of German parentage, was educated at a school near Bal- lygaran, and learned the carpenter's trade. In 1758 he joined the Irish Methodist conference as a preacher. He emigrated to America in 1760, settled in New York as a carpenter, and in 1766, upon the advice of Barbara Heck, commenced preaching, first in his own house, and soon after in a rigging loft, afterward famous as the birthplace of Methodism in New York. The first Methodist church was erected under his charge in 1768, on the site of the ex- isting John street church, he himself working upon the building as a carpenter. He preach- ed here without salary until the arrival in 1769 of missionaries sent out by Wesley, when he resigned and emigrated to Camden, where he worked at his trade during the week, and preached on the Sabbath. He organized a Methodist society, chiefly of Irish emigrants, at Ashgrove, seven miles distant from Camden, being the first Methodist organization within the bounds of what is now the Troy conference. He died suddenly, in consequence of an acci- dent in mowing, and was buried on a neigh- boring farm ; but in 1832 his remains were re- moved to Ashgrove churchyard, and in 1866, by order of the Troy conference, to the Wood- land cemetery, Cambridge, N. Y. EMDEN, or Embden, a seaport town of Prus- sia, in the province of Hanover, on the Dollart estuary, near the mouth of the Ems, 45 m. N. W. of Oldenburg; pop. in 1871, 12,588. The harbor is shallow, but the roadstead is ca- pable of accommodating largo vessels. Canals EMERALD 56T intersect the town in various directions ; one connects it with the town of Aurich, and an- other (opened in 1847, at a cost of $300,000) with the Ems. It is protected by a high and strong embankment against the incursions of the Dollart, from which it has frequently suf- fered. ^ Although the town has declined in population and prosperity, it continues to be the most important commercial town of Han- over. About 400 vessels enter and leave the port annually, and ship building is extensively carried on. Emden is of very ancient origin, and resembles more a Dutch than a German town. In the present century it has passed through the hands of Prussia, Holland, and France, came to Hanover in 1815, and in 1866 was again incorporated with Prussia. EMERALD (Sp. esmeralda ; Gr. o/mpaydof, from afiapdcasiv, to shine, whence the old name of smaragd and the German Smaragd), a name given to the finest crystals of the mineral species beryl, transparent and of rich green colors derived from oxide of chrome, which is present in the proportion of about 1 per cent., but, according to Vauquelin, sometimes as much as 3*5 per cent. (See BERYL.) They are found in metamorphic rocks, the granites, and mica schists. The finest specimens come from near Muzo, N. N. W. of Bogota, South America. Here it occurs in isolated crystals or in nests in a clay slate, a rock containing cretaceous fossils in its limestone concretions, and not in veins, as has been stated. A perfect hexagonal crystal from this place, 2 in. long and measuring across its three diameters 2^, 2, and 1|- in., and weighing 8 oz. 18 dwts., is in the cabinet of the duke of Devonshire. A still finer specimen, but only 6 oz. in weight, is in the possession of Mr. Hope, and cost 500. Emeralds of much larger size, but of less beau- ty, are found in Siberia, on the river Tokovoya, in mica schist. One in the royal collection is 14^ in. long by 12 broad, and weighs 16f Ibs. troy. The true emeralds of the ancients are said to have been principally obtained from Mt. Zabarah in Tipper Egypt, where the old work- ings were discovered by the French traveller M. Cailliaud, and reopened by Mehemet Ali. They are, however, inferior to the South American gems. The Peruvian emeralds were famous from the time of the conquest of that country by Pizarro. They were obtained in the barren district of Atacama, and worked by the native artists with the skill of the modern lapidary. To this day a river and a village of Ecuador are known by the name of Esmeral- das, from the abundance of emeralds formerly found in that region. Mexico at the same early period had produced crystals of rare beauty, which were no less appreciated and highly valued by the rulers of the Aztecs than were those of Peru by its incas. For one of the fine emeralds brought by Cortes on his return to Europe some Genoese merchants are said to have offered him 40,000 ducats. They had been cut by the exquisite workmanship of the
