On a Collection of Helminths from a South African Farm

Abstract

During the winter of 1925–1926 the writer had the opportunity of staying on a farm in the Northern districts of Natal, South Africa. This farm—about 1,000 acres in extent and situated some 4,000 feet above sea level—is used primarily for sheep grazing, although cattle, horses and goats also form part of the farm stock. Half of the farm consists of a mountain rising to just above 5,000 feet above sea level, and the rest of the farm consists of an undulating plain. Except for a few depressions towards the foot of the mountain, which, during the rainy season become somewhat swampy, the whole farm may be considered as being very well drained. In consequence it is entirely covered with grass, there being no evidence of bush formation. Three rivulets, giving an abundant water supply, take their origin from the mountain.
