Each langue had its own quarters at the Convent known as the "Auberge," presided over by a "conventual bailiff," who in all matters was the head of the langue. Each conventual bailiff had an important office in the hierarchy of the Order which was permanently appurtenant to the headship of that langue. Thus the conventual bailiff of the langue of France was always the Grand Hospitaller in charge of the Hospital of the Order, while that of England was Turcopolier, or commander of the light cavalry--a survival from the Syrian days. The possessions of each langue in its native land were divided into grand priories and bailiwicks. Thus England, which meant the possessions throughout the British Isles, was divided into the Grand Priory of England at Clerkenwell, the Grand Priory of Ireland at Kilmainham, and the Bailiwick of the Eagle, which was situated near Lincoln and had originally belonged to the Templars. These Grand Priors and Bailiffs of each langue, as well as its conventual bailiff, were all Knights Grand Cross, and, as such, entitled to seats in the Chapter-General of the Order.
The supreme control of the Order was vested in the Chapter-General, consisting of all the Knights Grand Cross. Though these Chapters-General were often convened in the early history of the Order, their difficulty of assembly and their clumsy method of procedure made them less and less frequently summoned, as the Grand Master had it in his power to convoke it when he pleased, though an interval of five years--later extended to ten--had been sanctioned by custom. In the seventeenth century the institution fell into utter disuse, and there was no meeting of the Chapter-General from 1631 to 1776, when its uselessness was finally demonstrated.
When the Chapter-General was not sitting the government of the Order was carried on by the Grand Master and the Councils, known as the Ordinary, Complete, Secret, and Criminal. The Ordinary Council consisted of the Grand Master, the conventual bailiffs, together with any Grand Cross residing at the Convent. This Council, as its name indicates, transacted the ordinary business of government, which mainly consisted of appointing to these offices and making those arrangements which were not definitely assigned to the Grand Master himself. The Secret and Criminal Councils, respectively, dealt with foreign affairs and offences against the Statutes, while the Complete, consisting of the Ordinary Council with the addition of two Knights from each langue of more than five years' residence at the Convent, dealt with appeals from the other Councils. In the later days of the Order the pernicious practice of appealing to the Pope destroyed all semblance of authority in this Council.
