of coal passing. Three boilers were in operation at a temperature of about 800 deg. C., the steam being passed through pipes round the boiler in order to superheat it. This is because a drop of water in the generators is liable to cause a dangerous accident in fact, about four years ago a drop of water, condensed in the main 20,000 kilowatt generator dropped onto the revolving plates and, due to the high speed, the blades were buckled and the sudden buckling caused the generator to break in two. The steam pipes were lagged with asbestos to prevent condensation and steam traps were in use as an extra precaution. Platinum resistance thermometers were used to measure the temperatures of the steam. Five small 6,000 kilowatt generators were in operation when we were there ; they differed from small dynamos by the fact that the magnets revolved and not the wires. We were next shown over the switchboard controlling the current to all the York areas and various other generating stations. The last place we visited was the cooling tower, which is just a tall open shaft through which there is a constant draught. Water pumped up from the River Foss trickles down over laths in the tower and is cooled down to a temperature suitable for cooling the generators. The cooling tower, of course, is not used in winter time. The total output of the Station is 35,000 kilowatts, which will be increased to 55,000 kilowatts when the large generator is repaired. :
THE SCHOOL PLAY-"MACBETH" 12th, 13th and 14th December, 1946
When we last saw "Macbeth," in December, 1941, we were at the beginning of the long uphill fight which ultimately brought the end of the war against Hitler. At that moment the situation in Europe seemed very like that of Scotland in Shakespeare's play, when "Good men's lives Expire before the flowers in their caps, Dying or ere they sicken," and many were asking "Stands Europe where it did ?" This similarity was pointed in the prologue, and the time was foreseen when the modern tyrant, too, tied as a bear to the stake, would have to fight the powers which would ultimately overwhelm him. But in 1941 that moment seemed a long way ahead, and now that we have seen its realisation, it was surely fitting to go back to the same play, and through it, to look back upon the road we have travelled. :
