- n. A hill of plants so prepared as to be forced beyond its season just where the plants grow.
Sorry, no etymologies found.
The forcing-hill is an arrangement by means of which a single plant or a single "hill" of plants may be forced where it permanently stands.
This type of forcing-hill is not much used, because the bank of earth is liable to be washed away, and heavy rain coming when the glass is off will fill the hill with water and drown the plant.
A forcing-hill is sometimes made by digging a hole in the ground and planting the seeds in the bottom of it, placing the pane of glass upon a slight ridge or mound which is made on the surface of the ground.
An excellent type of forcing-hill is made by the use of the hand-box, as shown in Fig. 192.
