No matter what the phase of soil study may be, texture and class are sure to have some important influence and must be included in the investigation. Prom observations in practice, certain crops have been found to be adapted to certain kinds of soil — as clay loam for wheat, silt loam for corn, loam or sandy loam for potatoes, clay or clay loam for timothy, and so on. Two authors ^ have determined the mechanical qualities of soils well adapted to certain crops. An average of their analyses is given below: — ^Hall, A. D., and Russell, B. J.
