Successive failures in attempts to deal with peat as fuel on a commercial scale have been so discredited that there is great danger that Irish engineers and capitalists-remembering these failures and not inquiring into the causes-may allow the exploitation of our great industrial asset to pass into the hands of outsiders-to their profit and not to our credit. I am, however, firmly persuaded that through work already done and advances already made it is a very ordinary bit of engineering work,

Lest it should be supposed that this is an over-statement, let me put the matter in a way which will appeal to engineers. In Engineering, vol. 83, p. 65b, 1907, an account of a recent test of a peat gas and ammonia recovery plant was given as follows, the gas being used to drive a gas engine : " The method adopted in the experiments at Winnington was Dr. Caro's process for the gasification of inferior fuels by means of air and superheated steam. The experiments were made in the Mond gas plant, and the resulting gas utilised in the gas engines; the superintending engineer was not informed that he was burning a special mixture, and he did not notice any difference. The peat came from Italy, the special machinery having been constructed for that country. Altogether 650 tons of this peat were gasified. The peat contained about 40 per cent, of water-the percentage varied-and in the dry state 15*2 per cent, of ashes, volatile substances 43'8 per cent, nitrogen r6 per cent., and 34 per cent, of carbon. A ton of dry peat yielded 1,780 cubic metres of gas of 1,360 large calories (about 150 B.Th.U. per cubic foot), and 118 lbs. of ammonium sulphate ; this amount of ammonia was really obtained, and not only calculated. The gas generated was partly utilised for raising the steam required for the process, and also for evaporating the ammonium sulphate, and it gave, in addition, 480 horse-power hours in
