The "Quillota" Cactus 



After inspecting a field like this, one has no hesitancy in 



accepting the statement that the new growth of slabs and fruit 



on an acre of perfected Opuntias may amount to 150 tons in a season. 



It may be questioned whether there is any other type of 



vegetation that transforms inorganic into organic 



matter at such an astounding rate.
