M eetings 55papers were presented, each followed by a discussion. Mr. J.Mulqueen of the Agricultural Institute in a paper on GrazingPotential on Wet Drumlins stressed the extreme impermeability ofthese soils, which cover an area of about 1.2 million acres in theRepublic, and the great difficulty, if not impossibility, of achievingany degree of satisfactory drainage in them.The Place of Forestry on Marginal Land was the title of a papergiven by Mr. N. Morris of the Forest and Wildlife Service, in thecourse of which he showed that in such areas the employment contentof forestry is at least as good as that of agriculture. He also advertedto the overproduction of agricultural produce in Europe and thehigh cost in subsidies.Mr. B. C. Hickey of the Agricultural Institute gave a paperentitled Economic Aspects of Grazing and Forestry on Marginal Lands.This was a rather pioneering attempt to make a direct economiccomparison between the two enterprises. He found that on wetdrumlin land a random sample of farms showed a lower rate ofreturn than that obtainable from forestry.One of the most interesting comments of the symposium was thatmade by one contributor who, besides farming in a big way, alsoacts as a financial consultant and advisor. He suggested that, takingcurrent inflation rates into account, a discount rate of 2.5-3.0 %might be more realistic for forestry calculations. He' pointed out thatan investment of £1 00-£ 120 in afforestation in Leitrim could purchasea present value of about £350 when discounted at 3.5 %. This wouldbe very attractive to an investor who was not too concerned aboutshort-term income.N. O'Carroll
Notes and NewsCOVER PHaIOGRAPHThe corver shows :a plrane tree (X Platanus acerifoli'a) ,in thegrounds of the Natural History Museum, Me,rion Street, Dublin,photographed on 24th November 1971. It can be seen that nearlyall of the leaves have fallen, with the exception of a large numberin that portion of the crown subject to the influence of the nearbystreet lamp.AERIAL FERTILIZATIONTwo trials of aerial fertilization by he:icopter were carried out bythe Forest and Wildlife Service, Dublin, recently. Both trials werein Co. Wicklow. In Blessington forest 88 ha (217 acres) were treatedin November 1971, and at Ballinagee forest an area of 215 ha(532 acres) was covered in March 1972. With the increased appreciationof the importance of fertilizat'on in timber production thisis a practice which will develop rapidly in future, as it alreadyhas done in some countries, notably Finland and Sweden. In thosecountries, with their relatirvely flat topography and large blocks offorest, fixed wing aircraft can be used. Conditions in Ireland aresuch that helicopters will normally be more economic. Theseconditions are: relatively rugged topography, lack of suitable air-
