220 CONE CONEJOS triangle be revolved about one of the sides forming the right angle, the other side will de- scribe a circle and the hypothenuse will de- scribe a right cone. In popular usage the cone is considered as limited to that portion of the figure between the vertex and the base ; but in mathematics the line describing the cone is supposed to extend indefinitely beyond the base, and the mathematical cone is consequently a figure of boundless extent. Every straight line drawn from the vertex through the curve enclosing the base is called a side of the cone. Every such line of course represents one of the positions of the line by which the cone is supposed to have been described. . The dis- tance from the vertex to the base measured on any one of these lines is called the slant height. The perpendicular distance from the vertex to the plane of the base is called the altitude of the cone. The study of the right cone is sufficient for most practical and scientific purposes. (See CONIC SECTIONS.) The area of the surface of a right cone is equal to one half the circum- ference of the base multiplied by the -slant height. The volume or solidity of a right cone is equal to one third the area of the base multiplied by the altitude. The name cone is given to the fruit of the pines and larches, from their resemblance to this figure. CONE, Speneer Hooghton, D. D., an American clergyman, born in Princeton, N. J., April 30, 1785, died in New York, Aug. 28, 1855. At the age of 12 he entered Princeton college, but two years later the infirm health of his father made him the only support of a large family, and he became Latin teacher in the Princeton academy. He afterward taught school at Bur- lington, N. J., and subsequently in Philadel- phia, where he enfeebled his health by the combined labors of teacher, law student, and copyist. One of his friends, an Episcopal bishop, advised him to take orders in the Epis- copal church, from which, however, he was withheld by the fact that he was a Baptist, and of a family which had been Baptist during many generations. The next advice of the bishop was that he should avail himself of his remarkable voice, and other superior physical qualifications, by going upon the stage. This he prepared to do, and in 1805 he appeared in the old Chestnut street theatre, Philadelphia, and at once took considerable rank. For seven years he followed this profession with great success, chiefly at Philadelphia, Baltimore, and Alexandria. In 1812 the lady to whom he was engaged refused to marry him unless he abandoned the stage ; which he did, and be- came editor of the "Baltimore American" newspaper. He soon after joined a regiment and served against the British in the engage- ments connected with their attacks on Balti- more and Washington. At the instance of George M. Dallas, whose father was secretary of the treasury, he obtained an appointment at "Washington ; and as he now contemplated the Christian ministry, he began to preach in some of the neighboring churches. He im- mediately excited general interest, attracted thronging audiences, and was chosen chaplain to the congress of 1815-' 16. He was settled in Alexandria until 1823, when he accepted a call to the Oliver street Baptist church in New York city, of which society he held the pastorate till 1841, when he exchanged it for that of the first Baptist church in the same city, which he retained till his death. He was a leading member of the Baptist general con- vention of the United States, and became its president in 1832 ; was foremost in directing the measures of the societies of home and for- eign missions; took part in the discussions which resulted in the secession from the Amer- ican Bible society of the American and foreign Bible Society, of which he was chosen presi- dent ; and in 1850 was one of the authors of a tract calling for a new translation of the Bible, more definitely in accordance with Baptist views, which occasioned an exciting contro- versy within the Baptist body. The result of the discussion, however, was that the proposal was negatived, and then Dr. Cone prompted the formation of the American Bible union, of which he was made president. A memoir of his life was written by his sons, and published in New York in 1856. CONECUH, a S. county of Alabama, drained by Escambia river, Burnt Corn creek, Murder creek, and Sepulgah river ; pop. in 1870, 9,574, of whom 4,901 were colored. The former area was 1,430 sq. m., but a portion has re- cently been taken to form Escambia county. It has a hilly surface, with a sandy, sterile soil. The forests furnish large quantities of pine timber, which are conveyed down the Conecuh in small rafts. Near Brooklyn, in the E. part, is a large cave. The Mobile and Mont- gomery railroad passes through the county. The chief productions in 1870 were 92,177 bushels of Indian corn, 12,550 of sweet pota- toes, and 1,539 bales of cotton. There were 425 horses, 1,769 milch cows, 2,298 sheep, and 4,433 swine. Capital, Sparta. CONEJOS, the S.W. county of Colorado, oound- ed N. E. and E. by the Rio Grande, which also intersects the N. part, S. by New Mexico, and W. by Utah; area, over 11,000 sq. m. ; pop. in 1870, 2,504. It is watered by the Conejos and other tributaries of the Rio Grande, and also by tributaries of the San Juan. The sur- face is broken by mountains, the Sierra Madre and Sierra La Plata ranges traversing the county. There is a large area of arable land. The W. part is occupied by the Ute Indian res- ervation. The precious metals are found in the mountainous parts, but are little worked. Gypsum also occurs. The inhabitants are chiefly Mexicans and half-breeds. The chief productions in 1870 were 9,222 bushels of wheat, 852 of oats, 2,001 of potatoes, and 71,076 Ibs. of wool. There were 548 horses, 1,791 milch cows, 2,178 other cattle, and 35,538 sheep. Capital, Guadalupe.
