About two o'clock
It had rained all day Friday , thanks to a merciful Providence , and the roofs were thoroughly soaked . Toward night it began to freeze , and the rain turned to sleet . By ten o'clock , when I went to bed the wind was blowing a terrible gale from the northwest , and everything loose about the building was banging and rattling . About two o'clock I suddenly started wide awake , with a bright light in my eyes . I jumped out of bed and ran to the window . The carriage house was a mass of flames , and a shower of sparks was sweeping over our eastern wing . I ran to the bathroom and leaned out of the window .
