The number of milch cows had increased to 3,090, that of other cattle to 6,124, horses and mules to 1,991, and sheep to 8,937, while the number of hogs had decreased to 7,022. In the census year 1900 the population was 7,759. Ninety-six per cent of the total area of the county was then in farms, and 58.5 per cent of the farm land was improved. Hay was still the leading crop, occupying 10 per cent of all the improved farm land, or 9,315 acres. Corn, the second crop in acreage, occupied 8,895 acres, and oats 3,680 acres. The other crops maintained the same relative importance they held 10 years previously, with the exception of buckwheat. This cereal occupied 2,016 acres in the 1900 census year, ranking as the fourth crop in point of acreage. Wheat was reduced to 1,324 acres. The census of 1900 showed small decreases in the number of cattle and hogs and increases in the number of horses, mules, and sheep. Within the period 1903-1905 the Norfolk & Western Railway extended its line to Galax, Va. This made the nearest shipping point for live stock and other farm products only 21 miles distant from Sparta, and the construction of this line has been an important factor in the development of the county. The population of Alleghany County remained practically sta- tionary between 1900 and 1910, but the 1910 census shows a gain of 13 per cent over 1900 in the total acreage of improved land, and an increase in the number of farms. The census reports the entire area of the county as being in farms and 63.8 per cent of the land as improved. The agriculture of Alleghany County at the present time consists of the production of hay, corn, and buckwheat and the raising of beef cattle. Hay occupies a larger acreage than any other crop. The 1910 census shows 11,132 acres devoted to tame and cultivated grasses, with a yield of about 1 ton per acre. The hay consists mainly of redtop or orchard grass or of these two grasses mixed. All the hay produced is consumed on the farm in the wintering of cattle. According to the census, there were 8,649 acres planted to corn in 1909, the crop amounting to 189,666 bushels. Corn is grown for the feeding of work stock and the fattening of hogs, as well as for domestic use. Practically no corn is sold. Buckwheat was sown on 3,650 acres in 1909, with a production of 51,358 bushels. Buckwheat is grown for revenue and the bulk of the crop is sold in outside markets. Minor crops of Alleghany County include rye, wheat, oats, Irish potatoes, cabbage, dry beans, and other vegetables. The cereal crops SOIL SURVEY OF ALLEGHANY COUNTY, NORTH CAROLINA. 11 and Irish potatoes are used mainly on the farms, but a small quantity of cabbage and Irish potatoes is sold in near -by towns. Vegetables make good yields and the product is of excellent quality. Of the fruits grown, apples are the most important. The principal varieties grown are the Virginia Beauty, York Imperial, Winesap, Limbertwig, and Rome Beauty. The quality of the fruit is high and indications are that with the establishment of good transporta- tion facilities apple growing will be extended on a. commercial scale. Cherries do exceptionally well in this county. A large quantity of chestnuts is gathered annually from the forests. ' The raising of beef cattle is the most important and in many cases the sole source of farm income. The census reports the value of all animals sold or slaughtered in 1909 as $398,326. There are probably 15,000 or more head of cattle in Alleghany County. Nearly every farmer raises cattle, the number on the individual farms ranging from a few head to a hundred or more. The principal breeds of cattle are the Hereford, Shorthorn, and Aberdewn Angus, with their grades and crosses. The cattle are grazed during the summer and fall. They are sold in the fall at the age of 2 or 3 years, when they weigh 900 to 1,200 pounds. Local buyers send the cattle, for finish- ing, to Pennsylvania or Virginia. A considerable proportion of the stock goes to Lancaster, Pa., where the animals are fed for 6 to 8 weeks. The cattle from Alleghany County compare favorably in quality with beef cattle from the Middle West. Sheep raising is an important agricultural interest. The number of sheep in the county is more than 12,000. Sheep are raised to be sold to outside markets. Wool and mohair produced in 1909 reached a value of over $9,000. The 1910 census reports 4,432 hogs in Alleghany County. Hogs are raised mainly for consumption on the farm, but a few head are sold. Poultry raising is a source of considerable farm revenue, the census reporting the value of poultry and eggs produced in 1909 as $56,893. A large number of turkeys are raised and driven to market. The surface configuration of the county is not favorable for the extensive cultivation of crops. The only areas that can be economi- cally used for cropping are the bottom lands along the watercourses, the smoother slopes and foothills, and the flat-topped mountain ridges and rounded knobs. Corn and grain are grown on the hill and mountain slopes, but the proportion of land occupied by these crops is very small in comparison with that utilized for pasture. Some recognition is given by the farmers to the adaptation of crops to the various soils of the county, but factors others than soil adaptedness govern in large measure the selection of fields. The 14 FIELD OPERATIONS OF THE BUREAU OF SOILS, 1915. gration and decomposition of the underlying rocks. The principal rocks are gneiss, mica gneiss, mica schist, and granite, together with hornblende and garnetiferous schist and dikes of other hard intru- sive rocks. The covering of soil material over the bedrock is generally shal- low, and in many places the partially decayed rock is reached be- tween the depths of 18 and 36 inches. Outcrops of the bedrock occur on slopes where erosion has kept close pace with soil formation. The quartz occurring in narrow bands or veins in the original rocks has resisted the agencies of weathering. The veins have merely broken up and the fragments are encountered on the surface, in the surface soil or embedded in the subsoil. In many places mica schist and mica gneiss are associated so closely in occurrence that difficulty is encountered in distinguishing between the resultant soils. With the range in physical and chemical composition of the under- lying rocks and differences in the stage of decay and oxidation of the component minerals, soils have been derived which vary in color, structure, origin, and other characteristics, but a uniformly loamy texture and dominantly friable structure are characteristic of practi- cally all the surface soils. The soils are classed in series which differ in color, structure, mode of origin, or other characteristics. Five series are recognized. The upland soils are comprised in the Ashe, Chandler, Porters, and Talla- dega series, and the bottom -land soils in the Toxaway series. The Ashe series is characterized by light -brown to yellowish sur- face soils and brownish -yellow or slightly reddish yellow, friable clay subsoils. The Ashe very coarse sandy loam and loam are encoun- tered in Alleghany County. The loam is derived from gneiss, granite, mica -gneiss, and garnetiferous schist, while the very coarse sandy loam is derived from coarse -grained granite. The Chandler series comprises yellow or brownish-yellow-ssurface soils and dominantly yellow subsoils. The surface soil and subsoil carry sufficient quantities of mica to give them a greasy feel and a lustrous appearance. The Chandler soils are derived mainly from mica schist and more rarely from mica gneiss. The Chandler loam is the only member of this series mapped in Alleghany County. The Porters series is characterized by brown to red surface soils and red or brownish -red subsoils. The members of this series are derived from hornblende schist, gneiss, granite, and granitoid gneiss, locally associated with mica schist and mica gneiss. The Porters loam is the only representative of this series mapped in the present survey. The Talladega series differs from the Porters principally in that the surface soil and subsoil are slightly less compact, are somewhat SOIL SURVEY OF ALLEGHANY COUNTY, NORTH CAROLINA. 19 especially where the soil is derived from garnetiferous schist. The Chandler loam is largely confined to the higher altitudes, especially the crests of mountains. The drainage is thorough and generally excessive, being sufficient in places on the slopes to cause soil wash. The Chandler loam owes its origin to the weathering in place of mica schist, mica gneiss, and, less commonly, garnetiferous schist. About one-third of the total area of the type is utilized for agri- cultural purposes, the remainder supporting a forest growth con- sisting of mixed chestnut, white oak, red oak, chestnut oak, and white pine. In some places white pine is the most conspicuous growth. Only about one-third of the cleared land is cultivated, the remainder being used for pasturage. The crops grown consist of corn, rye, buckwheat, and hay. Wheat is seldom grown. Like the other soils of the county, this type is used in the main for the grazing of live stock and the production of subsistence crops. As the Chan- dler loam occupies the highest elevations in the county it is exposed to more severe winter conditions than the other types, and little fruit is grown except on south and east slopes. Here fruit can be success- fully produced. Crop yields reported for this type are: Corn, 5 to 12-1 bushels per acre; rye, 8 to 14 bushels; and buckwheat, 10 to 24 bushels. The hay crop is generally very light. Corn is usually followed by rye or buckwheat. Grass for hay or pasturage is generally sown with the buckwheat or harrowed in on rye in the spring. Except over small areas on the tops of ridges and on the gentler slopes, improved farm implements can not be used on the Chandler loam. The soil, however, is easily worked, it warms up quickly in the spring, and crops mature early. The type is deficient in organic matter. The manure available is usually applied to corn and rarely to other crops. The small grains, however, are fertilized with an acreage application of 100 to 300 pounds of 16 per cent acid phos- phate. The selling price of land of this type ranges from $20 to $40 an acre. The Chandler loam is generally less productive of grass and grain than the Talladega loam, but its productiveness can be greatly increased by the incorporation of stable manure and the plowing under of coarse forage, grain stubble, and green manuring crops. Deep plowing and thorough tillage would do much to increase the yields. PORTERS LOA31. The surface soil of the Porters loam is a dark -brown or reddish - brown loam, ranging in depth from 5 to 12 inches. The subsoil is a 20 FIELD OPERATIONS OF THE BUREAU OF SOILS, 1915. friable clay loam to compact clay of a red or light -red color, generally extending to a depth of 3 feet. In places, however, the disintegrat- ing bedrock is reached at a depth of 2 or 3 feet, and occasional ledges are exposed at the surface, especially on the steeper slopes. The surface soil in general has a mellow structure. The subsoil con- tains a sprinkling of mica scales, but these are less abundant than in the Talladega and Chandler loams and do not give the material a greasy feel. Included with this type are a number of small patches of Porters clay loam, formed by the partial or complete removal of the surface soil by soil wash, and a small patch of Porters stony loam. The most important developments of Porters clay loam are encountered near the public road north of Toms Devil Knob and south of Rock Creek School, as well as near the county line in the northwest corner. The stony loam differs from the typical loam only in having a scattered distribution of stones on the surface. A variation in the Porters loam occurs north of Edwards Crossroad, where the -surface soil is intensely red in color and the subsoil is a deep -red clay. Throughout the Porters loam there are included numerous areas and strips of Ashe loam and Talladega loam too small to separate on the map. The Porters loam is the second soil in point of extent. It occurs throughout the county, but less extensively in the southeastern part. It is largely developed in two belts, which, however, are not continu- ous. One of these extends from southwest of Whitehead to Eunice and beyond. The larger and more continuous belt begins southwest of Peden and extends to New River. The Porters loam occupies the lower mountain slopes, and hills and ridges of moderate elevation. It usually occurs in an intermountain position, and never on the tops of the highest mountains. The type in general is well drained, and in places on the steeper slopes the run-off is so excessive as to have partially or wholly removed the surface soil and gullied the subsoil. On the other hand, in small areas the type adjoins the bottom lands so gradually that drainage in the lowest part of the slope is not well established. The Porters loam is derived from the weathering or decay in place of hornblende schist, gneiss, mica gneiss, and less commonly granitoid gneiss, as well as from other igneous rocks. Slight differences in the parent rocks are largely responsible for the variations which occur throughout the type. About 75 per cent of the Porters loam is farmed, the remainder supporting a mixed growth of chestnut, red oak, white oak, chestnut oak, maple, ash, poplar, dogwood, and cucumber tree, with a thick undergrowth in places of rhododendron, laurel, and wild grape. About 50 per cent of the cleared land is used for the production of 22 FIELD OPERATIONS OF THE BUREAU OF SOILS, 1915. tend to a depth of 3 feet or more but generally grades into decayed rock at some depth between 2 and 3 feet. In spots the rock comes to the surface. There is generally pre -Sent in both surface soil and subsoil a sufficient quantity of finely divided mica scales to give an unctuous or greasy feel to the material. The mica content is usually more conspicuous in the subsoil in those places in which the parent rock is near the surface. The Talladega loam in Alleghany County is not uniform. The subsoil varies in color from red or reddish yellow to streaked red and yellow, all of these different colors being developed in some places within areas of a few square feet. In small depressions and coves the surface soil is rich brown in color and may exceed 12 inches in depth, while, on the other hand, on the steeper slopes the color is lighter and the soil covering more shallow. Not infrequently the surface -soil material is entirely removed, exposing the underlying red or reddish -yellow clay loam. If larger these spots would have been mapped as Talladega clay loam. The Talladega loam covers only a small total area, though it oc- curs in small areas in all parts of the county with the exception of the southeastern and extreme eastern sections. It is typically de- veloped west of Nile. The largest area occurs in the bend of New River near Sibyl. Isolated areas lie in the vicinity of Laurelsprings along the western county line and on the slopes to Piney Fork. The type is encountered elsewhere in many spots closely associated with the Porters loam. Usually the Talladega loam occupies the lower slopes of the moun- tains and knolls, but occasionally it is encountered on the crests of intermountain ridges. The surface is generally smooth, although in places the slope is rather precipitous. Drainage over the type is thorough and in places excessive. The run-off is rapid and occa- sionally the underlying mica schist is exposed by erosion. The Talladega loam is derived from the weathering or decay in place of the underlying mica schist and mica gneiss and associated igneous rocks. About one-half the total area of this type is used in agriculture. The remainder supports a growth of mixed chestnut oak, red oak, white oak, dogwood, maple, and poplar, with occasional pine and hemlock trees. Probably less than one-third of the land farmed is cultivated, the type being used mainly for pastures. The raising of beef cattle is the chief interest, and the crops grown are mainly used for subsistence of the stock. They consist of corn, rye, wheat, buck- wheat, and oats. In addition vegetables and small quantities of fruit are grown for home use. Fuller use of this soil for cultivated crops is prevented by the rough topography. SOIL SURVEY OF ALLEGHANY COUNTY, NORTH CAROLINA. 23 Yields on the Talladega loam vary widely with the methods of farming pursued. Corn yields 20 to 30 bushels per acre; rye, 10 to 15 bushels; buckwheat, 10 to 25 bushels; wheat, 10 to 20 bushels; oats, 20 to 35 bushels; and mixed hay, 1 to 12 tons. Farmers report that the type gives best yields in wet seasons as it is inclined to droughti- ness. Oats are reported an uncertain crop. The crop rotation practiced on the Talladega loam consists gen- erally of corn followed by wheat, buckwheat or oats, and grass. Sometimes wheat is used as a nurse crop for red clover when it is desired to grow this legume for soil -improving purposes, but grass and clover are more frequently sown with buckwheat or oats than with wheat. The grass crops include timothy, redtop, and orchard grass, and red or sapling clover. After the hay is cut the land is pastured for a period of three years or more. Plowing on the Talladega loam is generally shallow. Corn is rarely fertilized, and then only with stable manure. The small grains are usually fertilized with acid phosphate applied in quantities rang- ing from 100 to 300 pounds per acre. The Talladega loam is a good soil for the general farming crops, especially wheat, under favorable conditions, but it is not so produc- tive as the Porters loam or Ashe loam, and the pastures are not as permanent as on the latter types. The value of land of the Talladega loam ranges from $40 to $80 an acre, depending on the location and the grazing afforded. The Talladega loam is capable of considerable improvement, especially where it occupies favorable topography. Deep plowing, more thorough tillage, and adding to the generally deficient supply of organic matter will enable the soil to take up more moisture, so as to lessen the effects of prolonged droughts, and in other ways will increase crop yields. The more frequent growing of red clover in crop -rotation systems would do much to supply organic matter when the supply of stable manure is short. TO%AWAY LOAM. The surface soil of the Toxaway loam is prevailingly a dark -gray to dark -brown loam, having a depth of about 6 to 15 inches. The subsoil is somewhat variable in color and texture, but in general it consists of a light -brown to black loam or clay loam extending to a depth of 3 feet. Throughout the surface soil and subsoil, in many places, there is present a sufficient quantity of small mica scales to give the material a slick, greasy feel. Included with the type as mapped are spots where the soil is a black loam. This variation is developed particularly along Piney Fork and Meadow Fork Creek. Bordering the stream courses in 26 FIELD OPERATIONS OF THE BUREAU OF SOILS, 1915. The soils of the county are derived from gneiss, and other igneous and metamorphic rocks, the relation between the soils and the asso- ciated geological formations being very close. Six soil types and, in addition, Rock outcrop and Rough stony land are shown on the map. The upland soils belong in the Ashe, Chandler, Porters, and Talla- dega series, and the alluvial, first -bottom. soils in the Toxaway series. The Ashe very coarse sandy loam occurs in one small area in the southeastern part of the county. It is used for general farming. The Ashe loam is the most extensive type snapped. It is an excel- lent soil for the general farming crops, where the surface features are such that it can be farmed economically. The pastures on this soil are lasting. The Chandler loam is the least productive of the upland soils for general farming, but it is an excellent type, where the surface is smooth, for light farming and truck and fruit growing, and when economic factors have become more favorable can be developed along special lines. The Porters loam is generally considered the strongest soil in the county for the general farming crops. About three -fourths of the type is used for agriculture. The Talladega loam is very similar to the Chandler loam in agri- cultural value, but it is slightly more productive for grass and wheat. The Toxaway loam constitutes the principal hay land of the county. This soil is well adapted to grass and corn. Rock outcrop and Rough stony land are miscellaneous types of practically no agricultural value. 0
