THREE:"Which I shall be able to do," Lawrence interrupted.I had more trouble with a wretch who, being heavily wounded in both legs, lay on the top of a dune beyond Mariakerke. He was quite alone, and when he discovered me his eyes glistened, full of hope. He told me of his agonies, and beseeched me to take him to a house or an ambulance. However much I should have liked to do that, it was impossible in the circumstances in which I found myself. Nowhere, even in the farthest distance, was a house to be seen, and I tried to explain the position to him. But he turned a deaf ear to all my exhortations, and insisted that I should help him. It was a painful business, for I could not do the impossible. So I promised him, and took my oath that I should warn the first ambulance I met, and see to it that they came and fetched him.

FORE:I. FORE:Cores expand when heated, and require an allowance in their dimensions the reverse from patterns; this is especially the case when the cores are made upon iron frames. For cylindrical cores less than six inches diameter, or less than two feet long, expansion need not be taken into account by pattern-makers, but for large cores careful calculation is required. The expansion of cores is as the amount of heat imparted to them, and the amount of heat taken up is dependent upon the quantity of metal that may surround the core and its conducting power.
