"XVII. The compline being ended, you must go to bed. After the brothers have once departed from the hall, it must not be permitted any one to speak in public, except it be upon urgent necessity. But whatever is spoken must be said in an under tone by the knight to his esquire. Perchance, however, in the interval between prayers and sleep, it may behove you, from urgent necessity, no opportunity having occurred during the day, to speak on some military matter, or concerning the state of your house, with some portion of the brethren, or with the Master, or with him to whom the government of the house has been confided: this, then, we order to be done in conformity with that which hath been written: _In many words thou shalt not avoid sin_; and in another place, _Life and death are in the hands of the tongue_. In that discourse, therefore, we utterly prohibit scurrility and idle words moving unto laughter, and on going to bed, if any one amongst you hath uttered a foolish saying, we enjoin him, in all humility, and with purity of devotion, to repeat the Lord's Prayer.

"XXI. ... Let all the esquires and retainers be clothed in black garments; but if such cannot be found, let them have what can be procured in the province where they live, so that they be of one colour, and such as is of a meaner character, viz. brown. "XXII. It is granted to none to wear white habits, or to have white mantles, excepting the above-named knights of Christ. "XXIII. We have decreed in common council, that no brother shall wear skins or cloaks, or anything serving as a covering for the body in the winter, even the cassock made of skins, except they be the _skins of lambs or of rams_....
