Third reading (Daybreak: Lavabo and Second Morning Offices)
At daybreak, when daylight has been shining for a while, the prior, considering the work of the night and the length of the day, shall rise before the others, and sometimes earlier, sometimes later, and he shall shake the little bell that is hanging in the middle of the dormitory. Then all the brothers shall rise and, as it is said (in the section) pertaining to Matins, after they had attended to the necessities of their body, they shall go in procession to the lavabo with the juniors going in front. There they shall line up to wash themselves in accordance with the custom of the lavabo and, if it is not possible for all of them to wash at the same time, the juniors shall wash first. Hands clean, coming to the part of the cloister before the chapter room, they shall wait in turn for the rest, arranged there in the two choirs (i.e. left and right) facing each other, until all have washed. All must carefully avoid blowing their noses on the hand-towels, or rubbing their teeth (with them), or staunching blood, or removing any other impurity. This is to be likewise understood for the table-towels in the refectory and the other hand-towels in the church.
Next they shall enter the church and going into the choir and making a deep bow with their hoods thrown back, all shall take their appointed places. And in the manner of Matins after the Triple prayer has been said and the prior has given the ending stroke on the stall, making a bow they shall orderly go to receive their books and shall come to sit in the cloister in silence; next the juniors shall go with the teacher to the school. Then the priests can stay with their attendants and celebrate mass. If any of the most mature ones, however, would wish to stay either simply in the choir or before one of the altars for prayer, he shall not be prohibited. Let them, nevertheless, do this briefly and fittingly, and after their prayers they shall sit with the rest. And it should be known that in the silent hour, according to custom, no one is to sit without a book. The juniors, in fact, shall carry service books with them at all hours, whether the ones of silence or the ones of conversation.
