For the first time he became sensible he was cold. He had slept more than an hour without coat, waistcoat, or boots, and the raw chilliness of winter dawn had entered his blood and stiffened his joints. He did not know the hour; he felt no curiosity to know. He put on his coat, waistcoat, and boots. He was low and wretched. 'I shall never be so foolish as to sit up another night. She sat up last night, and I this. After all, there are some things to be approved of in the life of those people down there.' He was standing at the window once again. 'If they have natures too practical, vitalities too low to experience the highest privileges of pleasure, they are obliged to keep regular hours. They cannot, after the wear and tear of the day, sit up until winter daylight surprises them. If I had not sat up, I should not have had that dream. If I had not sat up, I should not feel so weak and depressed now. If I had not sat up, I should not have got that revolting shock. It is against nature to sit up. All living things retire with the sun except man. Of course there are exceptions; but all creatures that come out after dusk are unclean and loathsome. 'And yet some men must sit up all night, for the good of others: lighthouse-keepers, and policemen, and watchmen, and sailors at sea, and astronomers. 'Astronomers and, no doubt, other men of science. Other men of science! Other men of science! How chill and dismal the morning! Other men of science no doubt. Astronomy is a loyal science. If difficulties arose in reconciling it now and then with Revelation, the difficulties disappeared. But other sciences were ruthless, impious; they respected nothing, they would reconcile with nothing. They were arrogant autocrats, absolute iconoclasts. 'Out there, down beneath, were the honest hardworking men of London rising and going forth from their homes to their blameless work. While they had slept the policemen had watched over their lives and their properties; while they had slept these sentinel churches had watched over their spirits. Their lives were spent in daily toil and nightly sleep to fit them for the morrow's labour. When the day of rest came, they flocked to those, churches from which rose those towers and spires, and there gave thanks for benefits received, begged continuance of grace and favours, and humbly prayed that in the end, when the shadow of death fell upon them, they might be permitted to join the pious hosts around the Eternal Throne.
