Book excerpt: Excerpt from The Journal of the Royal Agricultural Society of England, 1912, Vol. 73 Now one way of looking at a soil whereby some estimate may be formed of its behaviour towards water and air is to submit it to a mechanical analysis which will grade it into groups of particles of particular sizes. From this point of view all soils are mixtures of little particles - some large like sand, which, whether coarse or fine, possess no coherence but fall into a loose powder when dry; some much finer, so as to be scarcely gritty between the fingers and some so fine that they will hang in water like a cloud for many hours, are quite soapy to the touch, and cohere firmly on drying. Coarse sand lies at one end of the scale, the finest pipe clays at the other, but it should be borne in mind that the coarsest sandy soil will always contain some fine sand, silt, and clay, while the purest natural clays are not free from sandy admixtures. Just as one could grade a gravel deposit into two inch, inch, half-inch and quarter inch material, the process of mechanical analysis separates, partly by sieves but chie y by settlement from water, the soil into fractions of known size, these fractions being arbitrarily selected but possessing certain characteristic, if not sharply defined, differences of behaviour.
