The doctor, who was easily the most musical of the four men, sang in a cheerful baritone: "The owl and the pussy-cat went to sea In a beautiful, pea-green boat." The geologist, who had held down the lower end of a quartet in his university days, growled an accompaniment under his breath as he blithely peeled the potatoes. Occasionally a high-pitched note or two came from the direction of the engineer; he could not spare much wind while clambering about the machinery, oil-can in hand. The architect, alone, ignored the famous tune.
