THE CHAIRMAN, Mr. R. H. Stanger (Vice-President), in proposing a vote of thanks to Mr. Gueritte for his paper, said that, although he had not been closely connected with the problem of the design of cooling towers of reinforced concrete, he had had to test, some of the materials used in their construction, and could testify to the excellence of those materials. As one who had had to work at heights of 80 ft. or so on a 9-inch plank when serving his t.ime, and knowing how uncomfortable one could feel under such circumstances, he was particularly appreciative of the ingenious manner by which the scaffolding was erected on the insides of the towers, as described in the paper.
