CORK UNIVERSITY PRESS has issued an Agricultural Bulletin, No. 4, with this title. It contains the record of some small-scale experiments, carried out at Cork and elsewhere in the Irish Free State, on the possibility of producing supplies of oil seeds upon Irish soils. Crops of hemp, linseed, poppy, sunflower, rape, mustard and Mercurialis annua have been raised with varying success, and the yield of oils determined, as also the main physical chemical characteristics of the extracted oils. The work has been under the direction of Prof. J. Reilly and Mr. Denis F. Kelly, of the Department of Chemistry, University College, Cork. Very indifferent success was met with in these preliminary trials with the annual sunflower and Mercurialis, and the authors seem most impressed with the possibilities of native grown poppy seed oil displacing cotton seed oil in the edible fat and soap industries in Ireland. These trials are, however, of a very preliminary nature ; they throw very little light upon the possibility or otherwise of large-scale cultivation of these crops under Irish conditions, but they do establish the yields and main characteristics of the oils to be expected from such oil seeds grown under such conditions.
