I first wrote to Dr. Byers and asked him to send me soil samples on which a mechanical analysis had -been made by the pipette method. Dr. Byers responded very kindly by sending me samples of twenty different soils, together with their mechanical analysis. I analyzed these soils by the hydrometer method and found that what the pipette method determined as clay, the hydrometer could determine in one hour and what the pipette method determined as the finer clay or colloids, the hydrometer method could determine in two hours. This preliminary comparison of the two methods showed that they agree' surprisingly well with few exceptions.
