Hedge.

Patent for a new way to plant hedges. This invention "consists in an improved method of planting and training the cactus-plant (preferably of the species known as the 'scabbard' or 'brush cactus') to adapt it to form a thick and impenetrable fence which shall resist the attacks of cattle, and will grow regularly and evenly after the young plants have been properly trained" (lines 13-20)
