speaker went on to consider the biological effects of radiation. Radiation could break down the molecules of a substance and was therefore capable of breaking down the elemental components of life itself. Calder Hall, the new British power station, was the next topic. This station is very similar in design to an ordinary station, differing only in the provision of energy by nuclear fission. After explaining the atomic bomb the speaker demonstrated the effect of a radioactive source on a gold leaf electroscope, which is discharged by the ionised atmosphere. The Manor presented the last meeting of the term. S. M. Badharn gave a detailed account of the breeding of trout for stocking rivers, etc. He enumerated the various precautions necessary to ensure hygienic conditions. W. Gibson then talked on the breeding of tropical fish. Not only were such considerations as temperature and food essential, but in many cases the parent fish had to be checked from enjoying a cannibal diet. G. Parkin then described the way in which coal is won from the coal face. Modern machinery has done much for the mining industry, but still much organisation is required to combat the effects of falling roofs, etc. The meeting closed with W. E. Montague tracing the development of the motor car from 1870 to the present day. Upon being questioned he proved reluctant to predict the shape of things to come. Altogether it seems scarcely possible to imagine a wider series of lectures than the Society has enjoyed (and profited by) this term.
THE BRITISH SHIP ADOPTION SOCIETY The "Clan Stewart" sailed on Voyage 6 from Glasgow on Friday, 13th July (no superstitions in the Clan Line !) and arrived back in Hull on 4th December. Thus the voyage occupied the summer holidays and almost the whole of this term. The route and some statistical details are given below. The outward cargo to East African ports was the usual mixed collection of manufactured goods; there was no cargo from Dar-es-Salaam to Port Pixie; the homeward cargo from Australia consisted of lead, wool, pollard, and flour, chiefly. Some extracts from Capt. Graham's account of the voyage are also given below. On Wednesday, 5th December, a party from the School had the pleasure of visiting the ship in King George V Dock, Hull. We were most hospitably received by Capt. Graham and his officers, who showed us everything that we could want to see, and gave the impression that they were enjoying it as much as we were. Most of the boys managed, in wandering around the ship on their own, to penetrate to corners which are exciting to the landsman though humdrum to the seaman—the Indian crew's galley was a particular attraction. There was an excellent tea, and altogether the visit was 32
