VI. HITHER might have been referred the advantages which were used to arise to the king from the profits of his military tenures, to which most lands in the kingdom were subject, till the statute 12 Car. II. c. 24. which in great measure abolished them all: the explication of the nature of which tenures, must be referred to the second book of these commentaries. Hither also might have been referred the profitable prerogative of purveyance and pre-emption: which was a right enjoyed by the crown of buying up provisions and other necessaries, by the intervention of the king's purveyors, for the use of his royal houshold, at an appraised valuation, in preference to all others, and even without consent of the owner; and also of forcibly impressing the carriages and horses of the subject, to do the king's business on the publick roads, in the conveyance of timber, baggage, and the like, however inconvenient to the proprietor, upon paying him a settled price. A prerogative, which prevailed pretty generally throughout Europe, during the scarcity of gold and silver, and the high valuation of money consequential thereupon. In those early times the king's houshold (as well as those of inferior lords) were supported by specific renders of corn, and other victuals, from the tenants of the respective demesnes; and there was also a continual market kept at the palace gate to furnish viands for the royal use[q]. And this answered all purposes, in those ages of simplicity, so long as the king's court continued in any certain place. But when it removed from one part of the kingdom to another (as was formerly very frequently done) it was found necessary to send purveyors beforehand, to get together a sufficient quantity of provisions and other necessaries for the houshold: and, lest the unusual demand should raise them to an exorbitant price, the powers beforementioned were vested in these purveyors; who in process of time very greatly abused their authority, and became a great oppression to the subject though of little advantage to the crown; ready money in open market (when the royal residence was more permanent, and specie began to be plenty) being found upon experience to be the best proveditor of any. Wherefore by degrees the powers of purveyance have declined, in foreign countries as well as our own; and particularly were abolished in Sweden by Gustavus Adolphus, toward the beginning of the last century[r]. And, with us in England, having fallen into disuse during the suspension of monarchy, king Charles at his restoration consented, by the same statute, to resign intirely these branches of his revenue and power, for the ease and convenience of his subjects: and the parliament, in part of recompense, settled on him, his heirs, and successors, for ever, the hereditary excise of fifteen pence _per_ barrel on all beer and ale sold in the kingdom, and a proportionable sum for certain other liquors. So that this hereditary excise, the
