Invermay Research Station has a total area of 1,300 acres and may be divided, like Gaul, into three parts: First-class Soil: About 200 acres flat, fertile, recent alluvium. Second-ciass Soil: About 400 acres undulating, yellow-grey earth, shallow, overlying clay derived from phonolite. T h i r d - c l a s s S o i l : About 700 acres, ridgy, some as above, some more recent and more basic volcanic soil, usually with boulders. About 400 acres of the last-mentioned have been reclaimed from gorse and scrub, mainly by use of the swamp plough wherever it could be taken, leaving the steepest gullies in manuka and the stony outcrops in gorse.
