Fifth Meeting. 12th August, 1873.
J. T. Thomson, F.R.G.S., Vice-President, in the chair.
New member.—Dr. Webster.
The Secretary laid on the table a complete Catalogue of the Library of the society.
1. “On a Smokeless and Self-feeding Furnace for Lignites and other Fuels, and the Utilization of the Waste Heat,” by Henry Skey. (Transactions, p. 25.)
The Chairman said he should like to have seen some practical men there that evening. There was abundance of coal in the Province, and it would be a great benefit if it could be utilized as suggested by Mr. Skey. He was glad the matter had been brought forward, for it was certainly worthy of very serious consideration. He would ask the author if the principle could be applied to dwelling-houses.
The author replied that it could be so applied with certain modifications. It was, however, principally intended for the raising of steam. As furnaces were now constructed there was a very great waste of heat; and the same in the case of ordinary fire-places, where a large portion of the heat escaped up the chimney. It took about one-fourth the fuel to give the draught. Could his principle be carried out, not only would one-fourth be saved in the value of the coal consumed, but we should be able to use any species of coal or lignite for domestic, and especially for steam, purposes. But it was true that great difficulties were in the way of utilizing heat in the way he had pointed out.
The Chairman remarked that the subject was one that would get more important with a scarcity of coal. He would certainly like to see Mr. Skey's project a success.
Mr. Gillies would certainly like to see the matter tested, and a machine constructed on the principle referred to. He hoped the author would pursue his enquiries into this subject still further.
The Chairman had no doubt that if the principle was a beneficial one there would not be wanting practical men to take the matter up.
Mr. Skey, in answer to a question, said there was no doubt that under his principle the coal would burn away more rapidly, but as long as it gave out the same heat this would be all the better.
Mr. Gillies said that, when at the Mosgiel Woollen Factory lately, he had been informed that the Green Island coal was used there, and that there was no comparison between its cost and that of Newcastle coal.
The postponed discussion on Dr. Lauder Lindsay's paper on Salmon Acclimatization then took place.
Mr. Webb said that the information and suggestions contained in this paper were of a most valuable character. If proper waters were found for them he thought Salmon from North America could be acclimatized quite as well as from other countries. He hoped the suggestions of Dr. Ransom would be carried into effect.
Resolved—That copies of Dr. Lindsay's paper be sent to the Colonial Government, the Provincial Government of Otago, and the Acclimatization Societies of Canterbury, Otago, and Southland; and that attention be, at the same time, called to the information supplied in this paper as to the suitability of the Pacific Coast of British America as a source of supply; to the suggestion of Dr. Ransom for the conveyance of ova in ice-cold water in swinging vessels;and to that of Dr. Lindsay, that the experiment of Salmon Acclimatization ought to be persisted in for several years regularly under the superintendence of experts.
The Chairman spoke in favour of the Southland waters over the Molyneux, as the latter was now charged with silt.
