. Beginnings in agriculture. Agriculture. 32 AGRICULTURE Different kinds of soils and locations are associated with different plant societies. In the hard-tramped door-yard a society of knot-weed and broad-leaved plantain, with occasional blades of grass and dandelions; in the fence row there is a society of briars and choke-cherries and hiding weeds; in the dry, open field, the wire-grass and mullein and scattered docks associate; in the old pasture the blue-grass and mullein and daisies and devil's paint brush live together; in the meadow there is timothy, the lowers growing clover, young grasses, and other plants among the grasses. Some plants associate only with certain others. Cockle associates with wheat, not with oats or corn.
