Sir Edward Coke (_Coke upon Littleton_, 77 A) is the original source of much confusion as to the nature of primer seisin, which he seems to have considered as a second and additional relief exacted by the Crown amounting to the whole rent of the first year. The Popes, he further held (equally erroneously), were only imitating this practice when they exacted one year’s rent from every newly granted benefice under the name of “first fruits.” These errors have been widely followed (_e.g._ Thomson, _Magna Charta_, p. 416, Taswell Langmead, _Const. Hist._, p. 50). ----- (_f_) _Fines for alienation_ occupy a place by themselves. Unlike other incidents already discussed, they became exigible not on the tenant’s death, but on his wishing to part with his estate to another during his own lifetime, either as a gift or in return for a price. How far could he effect this without consent of his lord? This was, for many centuries, a subject of frequent and heated disputes, often settled by compromises, in which the tenant paid a fine to the lord for permission to sell. Such fines are payable at the present day in Scotland (under the name of “compositions”) from feus granted prior to 1874; and, where no sum has been mentioned in the Feu Charter, the law of Scotland defines the amount exigible as one year’s rent. John’s Magna Carta contains no provisions on this subject. Disputes, long and bitter, took place later in the thirteenth century; but their history is irrelevant to the present inquiry.[109] ----- Footnote 109: See Taswell Langmead, _Const. Hist._, pp. 51-2; also Pollock and Maitland, II. 326. _Cf._, however, c. 39 of the re-issue of Magna Carta in 1217. ----- II. _Feudal Aids._ The feudal tenant, in addition to fulfilling all the essentials of the feudal relation and also all the burdensome incidents already enumerated, was expected to come to the aid of his lord in any special crisis or emergency. The help thus rendered was by no means reckoned as a payment to account of the other obligations, which had also to be paid in full. The additional sums thus given were technically known as “aids.” At first, the occasions on which these might be demanded were varied and undefined. Gradually, however, they were limited to three. Glanvill,[110] indeed, mentions only two, namely, the knighting of the overlord’s eldest son, and the marriage of his eldest daughter; but he intends these, perhaps, merely as illustrations rather than as forming an exhaustive list. Before the beginning of the thirteenth century the recognized aids were clearly three—the ransoming of the king and the two already mentioned. This understanding was embodied in Magna Carta.[111] ----- Footnote 110: IX. c. 8. Footnote 111: See _infra_, under chapter 12. -----
