PART III
ANALYSIS   OF   AGRICULTURAL  MATERIALS
The following chapters constitute an introduction to the appli-
cation of quantitative analysis to the solution of agricultural
problems. The subjects treated are typical phases of the broad
field of agricultural analysis. The student is especially cau-
tioned that if ho is to avoid the common danger of falling into
ways of mere mechanical routine ho must, hero as elsewhere,
cultivate the habit of looking for the scientific principles under-
lying his work, as well as for the significance of its results in
connection with scientific agriculture.
