M. The treasurer and chamberlains do not expend the money received, unless by express mandate of the king or of the presiding justice: for when the general account is demanded from them, they must have the authority of a rescript of the king concerning the money distributed; moreover this is the wording under which they are drawn up: "H. king, etc., to N. the treasurer and to this man and that man, chamberlains, greeting. Pay from my treasury to that or that man, this or this sum. These being witnesses before N. at the exchequer." Moreover " at the exchequer" is added that thus there may be a difference from the writs that are made in the curia regis. It is also necessary, when a writ is made concerning an outlay from the treasury, as we have said, that that same scribe shall make a copy of it, which is commonly called counter-writ; and this the clerk of the chancery shall reserve in his own possession, in testimony of the payment made through the original writ of the king, which the treasurer and chamberlains have. Also writs of computing or remitting those things which the barons shall have decreed should be computed or remitted—the will of our lord king having previously become known—are drawn up under this tenor of words: "H. by the grace of God, etc., to the barons of the exchequer, greeting. Compute to that or that man this or this sum, which he expended for this or that affair of mine. These being witness there at the exchequer." Likewise: "The king to the barons of the exchequer, greeting. I remit to that man, or quit-claim to this or that one this or that. These being witnesses there at the exchequer." Copies of all these writs shall remain with the aforesaid clerk, as a proof that the writs were made out. For the original writs of computations or remissions are enclosed in the boxes of the marshall when the accounts of the sheriffs are made up; for the rest, unless a dispute arise concerning them, they are not to be shown. Moreover, what we have said of the writs of the king is likewise to be understood of the writs of the presiding justice; but only when the king is absent and, with the impress of his seal, the laws of the kingdom are established and the cases are called, so that they who are summoned before the court are condemned or acquitted.
