heat hangs like a hot stove everywhere, they abstained from taking any water through one spell of thirty days, and at another time for nine." and described Jacinta as being hospitalized for severe bronchial illness, after which she confided to her older cousin that she was still abstaining: "I was thirsty, Lúcia, and I didn't drink, and so I offered it to Jesus for sinners." Lucia wrote in her 1936 and 1941 memoirs that the Virgin Mary predicted the deaths of Franiscco and Jacinta during the second apparition on 13 June 1917. In one of several memoirs, Lucia wrote that the children tied "penitence cords" so tightly around their waists that the ropes became blood-stained, and that the apparition of 13 September 1917, told her, "God is pleased with your sacrifices, but He does not want you to sleep with the rope on; only wear it during the day." Late in life, Lucia also wrote about doubts she expressed as a child regarding the authenticity of the apparition. She wrote, "I began then to have doubts as to whether these manifestations might be from the devil [...] truly, ever since I had started seeing these things, our home was no longer the same, for joy and peace had fled. What anguish I felt!" She also describes a vivid nightmare she experienced during this time period wherein "the devil was laughing at having deceived me." De Marchi states that Lúcia told her cousin prior to traveling to Cova da Iria in anticipation of the 13 July 1917 apparition, "If she [the Lady] asks for me, Jacinta, you tell her why I'm not there. Because I am afraid it is the Devil who sends her to us!" Lucia wrote in her memoir that on the following day, she was overtaken by a certainty that she should go, despite her earlier dread: "...when it was nearly time to leave, I suddenly felt I had to go, impelled by a strange force that I could hardly resist." According to De Marchi, "Lucia's doubts were mercifully dissolved".
