Excerpt from A Study of the Soils of the United States No industry is so vital to the well-being of a nation as agriculture and nothing SO vital to agriculture as the soil. From its treasury it has been estimated1 that we drew last year (1909) more than and its possibilities are as yet only partially realized. There are still in this country millions of acres which have never felt the plow, while those which are now under cultivation can, by the application of scientific principles, be made to produce many times the present value of their products. How to use and not abuse this great resource is the most important problem which faces the farmer of to-day - one worthy of the best efforts of our most pro found and learned scientists; for upon its solution depends the future prosperity of the nation.

Excerpt from Soils of the United States (Edition, 1913) The soil unit or the soil individual is the soil type. It connotes all the features named above and is limited to a single class, a single series, and a single province. A soil type, therefore, is a soil w ich throughout the area of its occurrence has the same texture, color, structure, character of subsoil, general topography, procca of derivation, and usually derivation from the same material.

Excerpt from Soils of the United States There have been surveyed and mapped to January 1, 1912, a total of square miles or acres. This mapping has been done on scales ranging from 1 inch equals 1 mile to 4 or 6 inches equals 1 mile in reconnoissance surveys. In addition to this an area of about square miles in the Ozark region of Missouri and Arkansas has been mapped in a more general reconnoissance. Including this and estimating the amount of work done in the 6 months from January 1 to June 30, the end of the fiscal year, it is estimated that there have been completed to the latter date square miles, an area nearly equal to the combined area of four of the most important countries of Europe, as follows.

Excerpt from Soils of the Eastern United States and Their Use XXXIX: Meadow The word Meadow, as applied to soil conditions and as used in the soil classification of the Bureau of Soils, designates those low-lying, frequently somewhat swampy areas found along stream courses and tidewater embayments, which are subject to overflow and which are chiefly devoted to pasturage and the production of hay, when used for agricultural purposes, though usually occupied by trees and dense undergrowth when in their natural condition. Meadow areas, according to this classification, are necessarily variable in texture, since they are among the youngest of soils. They are partially completed soil areas which are subject to frequent accessions of material which may be similar to that already deposited or may differ widely in texture from earlier deposits, depending upon the character of the successive overflows. The term Meadow as here used possesses the oldest significance of the word. This arises from the fact that before the introduction of the majority of grasses and clovers now used for seeding, the moist, low-lying lands supported a growth of the wild grasses that formed the chief dependence of the early farmers both for grazing and for hay. With the introduction of new grasses and with the spread of grass culture to the uplands, the term was transposed, together with grass growing, and the broader significance of the term was made to include the agricultural use of all land of any character where grass was grown for hay. The older use of the term, which is the definition adopted by the Bureau of Soils, is much more definite and significant for the purposes of soil classification. Areas of Meadow of various sizes occur along the courses of nearly all of the larger streams of the eastern portion of the United States. Wherever the bottom lands are subject to periodic overflow such soils may be formed. As a result of this condition along all stream courses where soil building is in progress, areas of Meadow have been encountered in 173 different areas, located in 31 different States and aggregating a total of 3, 086, 829 acres. This vast area constitutes but a small part of the total, and it may be safely estimated that not less than 20, 000, 000 acres of such soil deposits exist in the eastern part of the country.

Excerpt from Important Soils of the United States: Issued to Accompany a Collection of Soils and Subsoils (in 13 Boxes) For Use of Schools and Colleges Teaching Agriculture and Physical Geography The soils of the United States for purposes of classification grouped into seven soil provinces, covering the eastern half of United States, and six soil regions, covering the western half. 7 soil provinces differ in the petrographic and physical character the rock from which the soil material was derived, topography, vation, and in processes by which the soil material was accumulai The soil regions do not conform to differences in the mode of ori or method of transportation of soil material, but to great phys graphic regions, and the soils within each region differ in orig these differences being substantially the same as the differences t distinguish the different soil provinces.

Excerpt from Soil Survey Field Book: Field Season, 1906 Two years have elapsed since the publication of the last issue of Instructions to Field Parties and Description of Soil Types. During these years the soils of many new areas have been studied and much a'dditional information in regard to the general relation of the soils of the United States has been obtained. The correlation of the soils is a very difficult problem, and one which can not be definitely solved from the data obtained by the survey of a limited number of widely separated areas. Each additional survey throws new light upon the subject, and sometimes necessitates changes in the soil names used in the earlier reports. The student of soils will doubtless realize that the necessity for such readjustments is an inherent feature of work of this character.
