. The office of Lord High Treasurer is distinct from that of Treasurer of the Exchequer, albeit when the Treasury was held by an individual, he was invariably appointed to both offices. The appointment of Lord High Treasurer was made by the delivery of a
white staff to the appointee; whereas that of Treasurer of the Exchequer was made
at His Majesty's pleasure by
letters patent under the
Great Seal of the Realm. By the 18th century the appointment of a new Lord High Treasurer took place with elaborate ceremony within Westminster Hall and the Exchequer. The new Lord Treasurer, preceded by the
clerks of the Treasury, the officers of the Exchequer, his secretary and his
sergeant-at-mace, and attended by several Lords and
Privy Counsellors, proceeded first to the Court of Chancery where he made his oaths to the Sovereign before the
Lord Keeper of the Great Seal; then, accompanied by the Lord Keeper, he proceeded to the Court of Exchequer where the Lord Keeper, seated alongside the
Barons of the Exchequer, made a speech explaining the two distinct offices to which the Lord Treasurer was appointed. The latter took the oaths of each respective office, after which his patent was delivered to him and he took his place alongside the Barons. The Lord Keeper having departed, the new Lord Treasurer sat for a time hearing motions in the Court; afterwards he went to take formal possession of each office (or department) of the Exchequer, and then to the Exchequer of Receipt (where a
tally was ceremonially struck and the
Auditor presented to him the great keys of the Treasury). == Later history ==
