Examples

“The roots of plants, disengaged from the soil in the process⟳ of tilling and cleaning it, are also employed as a vegetable manure. Some of these, however, as the couch grass, being very vivacious, would readily spring⟳ again: and therefore it is necessary that their vegetative powers be destroyed, which may be done by mixing them with lime, and forming in this way a compost. Many farmers, however, to save⟳ time, or to prevent⟳ the risk⟳ of the plants springing again, burn them in little heaps upon the ground at the time of their being collected, and spread⟳ the ashes upon the surface. This may be sometimes convenient, but the effect is, that the principal nutritive part of the plant⟳ is dissipated, and nothing left but the carbonaceous, earthy, and other insoluble matter⟳. —Low's Elements of Practical Agriculture.”

“But the trouble⟳ was pervasive and deep-rooted as couch-grass.”

“The old couple who had lived there hadn't been able to do much and the garden was a wilderness of couch-grass and dandelion.”
