"A singular and increasing interest in agriculture and in the breeding of cattle; and if in some localities, on account of peculiar circumstances or of a less degree of intelligence, certain branches of the science of agriculture are less developed than in other localities, it is, nevertheless, undeniable that an almost universal progress has been made in the cultivation of the soil and in the breeding of cattle. No one can any longer, as was the custom thirty years ago, describe the Prussian system of agriculture by the single appellation of the three-year-course system; no man can, as formerly, confine his enumeration of richly-cultivated districts to a few localities.

He can give reasons for the occasional failures of his operations; he knows and remembers clearly his pecuniary resources; he arranges his choice of fruits according to their prices; and he makes his calculations by the general signs and tidings of the weather."--_Landwirthshaft der Rheinpfalz_.
