The first flows S. and joins White river 30 or 40 m. below Batesville, and is navigable for steamers during the greater part of the year a distance of 100 m. The Washita or Ouachita rises in the W. part of the state, S. of the Arkansas, runs S. and S. E. parallel with that stream, passing through a beautiful and fertile portion of southern Arkansas, thence S. through a portion of Louisiana, and joins the Red river near its junction with the Mississippi. It is navigable for about 350 m. from its mouth. Its chief tributaries are the Little Missouri, Saline, Bayou Bœuf, etc. - The mineral wealth of Arkansas is as yet comparatively undeveloped. It is known that the state abounds in cannel, anthracite, and bituminous coal, which is found in greatest profusion along the banks of the Arkansas river on either side, from a point a short distance above Little Rock to the western boundary of the state. Iron ore of a good quality has been found in the Ozark mountains. Zinc ore exists more extensively in Arkansas than in any other state of the Union except New Jersey. Galena or lead ore, frequently bearing silver, abounds in various parts of the state. Gold has been discovered in White county, but has never been profitably worked.

Manganese is abundant, and, according to De Bow, Arkansas contains more gypsum than all the other states in the Union. Near the hot springs in the Washita valley is an immense bed of superior oil stone, or novaculite, said to be equal to the celebrated Turkish oil stone. Salt of very good quality is produced from the saline springs in the vicinity of Washita and elsewhere. - The climate is temperate, but subject to sudden changes in consequence of the north winds. The temperature at Little Rock usually ranges from 15° to 99° F., and averages 62.66°, though the mercury has been known to fall as low as 8°. The mean temperature for the winter months is 45.82°; for the summer, 79.66°, the mercury reaching 90° or above for from 40 to 50 days during the summer. Terriflc thunderstorms prevail during the spring and summer. The precipitation of rain during i the months of July, August, and September, 1871, amounted to 9.23 inches at Mineral Springs, and 3.75 inches at Clarksville. - The total number of deaths in 1870 was 6,119, of which 2,096 were from general diseases; with respect to local diseases, the most numerous deaths were 639 from affections of the nervous system, 1,476 of the respiratory system, and 602 of the digestive system. - The soil of Arkansas varies from the richest and most productive to the most sterile; and the climate and productions are equally varied.

The river bottoms, composed of a black alluvium, are wonderfully fertile, producing bountiful crops of cotton, corn, tobacco, sweet potatoes, melons, peaches, grapes, and various other fruits. There are immense tracts of submerged bottoms equally rich, which might be brought under cultivation by a judicious system of drainage. Rising from the valley, the soil becomes less productive, and in many places will not repay cultivation; while large portions of the uplands, particularly in the northern part of the state, produce good crops of wheat and other grain, as well as the best of apples, and are well adapted to grazing. The uplands are largely interspersed with rolling prairies, which are generally well watered, though Grand prairie, 90 m. long and 30 broad, situated between Arkansas and White rivers, is an exception, being almost entirely without water. The low valleys are destitute of good water, the inhabitants resorting to rain water, which is collected and kept in large tanks sunk into the ground, and filtered river water. These valleys are very unhealthy, particularly to the unacclimated. The more elevated portions of the state are salubrious. - The productions of Arkansas are mainly agricultural.

The area of the state is 33,406,720 acres, and in 1870 there were 1,714,466 acres of improved and 3,791,873 of wood land. The cash value of farms was $36,457,476; of farming implements and machinery, $2,112,020; total amount of wages paid during the year, including value of board, $3,907,188. There were 83,952 horses, 33,381 mules and asses, 119,607 milch cows, 31,673 working oxen, 179,431 other cattle, 149,592 sheep, 772,662 swine; value of all live stock $15,795,971. The productions were 683,691 bushels of wheat, 23,422 of rye, 12,208,044 of corn, 486,425 of oats, 46,477 of peas and beans, 399,927 of Irish potatoes, 859,842 of sweet potatoes, 73,021 lbs. of rice, 529,110 of tobacco, 203,275 of wool, 2,531,011 of butter, 12,047 of wax, 261,824 of honey, 221,546 bales of cotton, 6,806 tons of hay, 00,272 gallons of cane and 138,859 of sorghum molasses; value of home manufactures, $723,-979; of slaughtered animals, $3,466,152; estimated value of all farm products, including betterments and additions to stock, $36,524,-008. The number of manufacturing establishments was 1,304; capital, $2,137,738. Of these the most important were 272 flour and meal mills, 283 establishments for ginning cotton, 35 for the manufacture of leather, 212 saw mills, and 13 wool-carding establishments. - The state is remarkably well stocked with wild animals, valuable for their meat, hides, and furs, among which are the deer, elk, beaver, otter, rabbit, raccoon, wildcat, catamount, wolf, and bear. "Wild turkeys, geese, quails, and various other birds, are also found in great abundance. - The chief exports are cotton, maize, wool, hides, and lumber, which find a market in New Orleans, through which port Arkansas receives her foreign merchandise.

A thriving domestic commerce is carried on along the Mississippi, Arkansas, and other navigable streams of the state; and the traffic with the Indians on the western border is of considerable importance. - Among the most striking natural curiosities in the state are the famous hot springs, beneficial to those suffering from the effects of mercury in the system, rheumatism, stiffness of the joints, etc. These springs are situated on a small tributary of the "Washita, about 0 m. from that river, and 00 m. S. W. of Little Rock, in Hot Springs county. From 75 to 100 of these springs, varying in temperature from 105° to 160° F., issue from a lofty ridge of sandstone overlooking the town, while a number rise from the bed of Hot Spring creek, which flows at the foot of the ridge, and, by reason of the springs, is rendered sufficiently warm for bathing in midwinter. In Pike county, on the Little Missouri river, is a natural bridge, and near by is a mountain of very fine alabaster. - Up to Jan. 1, 1870, only 128 miles of railroad had been completed in Arkansas; but many important lines are now in process of construction.
