Pieces of Hippeastrum roots were sent to the Nematology Department, Rothamsted Experimental Station, in July, 1950, by Dr. Morris Cohen, National Agricultural Advisory Service, Northern Province. They originated from a collection of these hothouse Amaryllids at Hexham, Northumberland. Later some more pieces of root and a potted plant, which was heavily infested, were received. Dr. Cohen had found eelworms associated with lesions on the roots and in the absence of other causes, thought they might be responsible for the damage to the roots and the consequent ill-health of the bulbs during the previous few years.


I am honoured and privileged to be Chairman for the opening session of this Royal Society Discussion Meeting on Scientific Aspects of Irrigation Schemes. It was originally intended that Dr Howard Penman, F. R. S., was to have been the Chairman for this session, but sadly he is no longer with us. However, his valuable work over many years at the Rothamsted Experimental Station on the physics of evaporation and the determination of the Penman equation lives on and is of continuing benefit to those concerned with irrigation development throughout the world. First, I would like to stress the importance of the subject of this discussion meeting to industrial and developing countries alike, and offer the following estimates of areas under irrigation and drainage-flood protection worldwide in support of this view.
