Acreage of the fiscal carucate.
To prove that the fiscal carucate was composed of 120 (fiscal) acres is by no means easy. If, however, we have sojourned for a while in Essex and then cross the border, we can hardly doubt that in East Anglia the carucate bears to the acres the relation that is borne by those hides among which we have been living. Norfolk and Suffolk are carucated counties, but while in the other carucated counties it is usual to express the smaller quantities of land in terms of the bovate (8 bovates making one carucate) and to say nothing of acres, in East Anglia, on the other hand, it is uncommon to mention the bovate—in Suffolk we may even find the virgate[1591]—and men reckon by carucates, half-carucates and acres. We allow the description of Suffolk to fall open where it pleases and observe a hundred consecutive cases in which a plot of land (as distinguished from meadow) is spoken of as containing a certain number of acres. In 22 cases out of the hundred that number is 60, in 8 it, is 30, in 7 it is 20, in 5 it is 40, in 5 it is 15; no other number occurs more than 4 times, and yet the numbers that appear range from 100 to 2. We have tried the same experiment on two hundred cases in Norfolk; in 28 cases the number of acres was 30, in 16 cases it was 60, in 13 it was 40, in 13 it was 16, in 12 it was 20, in 10 it was 80, in 9 it was 15, though the numbers ranged from 1 to 405. Surely the explanation of this must be that 60 acres are half a carucate, that 30 acres are a quarter, that 40 acres are a third, 20 a sixth, 15 an eighth. We have made many similar experiments and always with a similar result; wherever we open the book we find plots of 60 acres and of 30 acres in rich abundance. We use another test. When land is described by the formula ‘x carucatae et z acrae,’ what values are assigned to z? We find 40 very commonly, 42, 45, 50, 60 (but this is rare, for it is easier to say ‘x1⁄2 carucates’ than ‘x carucates and 60 acres’) 68, 69, 80 (at least four times), 81, and 100[1592]. On the one hand, then, we have a good deal of evidence that the carucate contains more than 80 acres, some evidence that it contains more than 100 acres, and some that it does not contain many more, for no case have we seen in which z exceeds 100. Perhaps in Norfolk the figure 16 occurs rather more frequently than our theory would expect, but 16 is two-fifteenths of 120, and the figures 32 and 64 occur but rarely. Also it must be confessed that in Derbyshire we hear of ‘eleven bovates and a half and eight acres,’ also of ‘twelve bovates and a half and eight acres[1593].’ These entries, to use an argument which we have formerly used in our own favour, seem to imply that half a bovate is more than eight acres and would therefore give us a carucate of at least 144. We can only answer that, though men do not habitually use clumsy modes of reckoning, they do this occasionally[1594].
Acreage of the fiscal sulung.
Of the Kentish sulung very little can be discovered from Domesday. Apparently it was divided into 4 yokes (iuga)[1595] and the yoke was probably divided into 4 virgates. We have indeed one statement connecting acres with sulungs which some have thought of great importance. ‘In the common land of St. Martin [i.e. the land which belongs to the communitas of the canons of St. Martin] are 400 acres and a half which make two sulungs and a half[1596].’ Thence, a small quantity being neglected, the inference has been drawn that the Kentish sulung was composed of 160 acres, while some would read ‘400 acres and a half’ to mean 450 acres and would so get 180 acres for the sulung[1597]. But the entry deals with one particular case and it connects real acres with rateable units:—the canons have 4001⁄2 or more probably 450 acres, which are rated at 21⁄2 sulungs. If we passed to another estate, we might find a different relation between the fiscal and the real units. Kent was egregiously undertaxed and as a general rule its fiscal sulung will have many real acres. Turning to the cases in which the geldability of land is expressed in terms of sulungs and acres, or yokes and acres, we can gather no more than that the sulung is greater than 60 acres, so much greater that ‘3 sulungs less 60 acres[1598]’ is a natural phrase, and that the half-sulung is greater than 40[1599] and than 42 acres[1600]. We may suspect that the Exchequer was reckoning 120 (fiscal) acres to the sulung but can not say that this is proved.
Kemble’s theory.
And now we must glance at certain theories opposed to that which has been here stated. Kemble contends that the hide contained 30 or 33 Saxon which were equal to 40 Norman acres, and that the hide of Domesday Book contains 40 Norman acres[1601]. Now in so far as this doctrine deals with the time before the Conquest, we will postpone our judgment upon it. So far as it deals with the Domesday hide, it is supported by two arguments. One of these is to the effect that England has not room for all the hides that are attributed to it if the hide had many more than 30 or 40 acres; this argument also we will for a while defer. The other[1602] is based on a single passage in the Exeter Domesday relating to the manor of Poleham. That entry seems to involve an equation which can only be solved if 1 virgate = 10 acres. William of Mohun has a manor which in the time of King Edward paid geld for 10 hides; he has in demesne 4 H., 1 V., 6 A. and the villeins have 51⁄2 H., 4 A.[1603] Now three or four such entries would certainly set the matter at rest; but a single entry can not. By way of answer it will be enough to say that the very next entry seems to imply an equation of precisely the same form, but one that is plainly absurd. This same William has a manor called Ham; it paid geld for 5 hides; there were 3 H., 8 A. in demesne and the villains had 2 H. less 12 A. Shall we draw the conclusion that 5 H. = 5 H. - 4 A.? The truth we suspect to be that here, as in Middlesex, geldable units and actual areal units have already begun to perplex each other. Both Poleham and Ham are what we call ‘over-rated’ manors. It is known that Poleham contains 10 hides and Ham 5 hides, but, when we come to look for the acres that will make up the due tale of hides, we can not find them; for let King William’s officers have never so clear a terminology of their own, the country folk will not for ever be distinguishing between ‘acres ad geldum’ and ‘acres ad arandum’ But be the explanation what it may, we repeat that the one equation that Kemble could find to support his argument is found in the closest company with an equation which when similarly treated produces a nonsensical result. This is all the direct evidence that he has produced from Domesday Book in favour of the hide of 40 acres. Robertson, while holding that the hide of Mercia contained 120 acres, adopted Kemble’s opinion that the hide of Wessex contained 40 without producing any witness from Domesday save only the passage about Poleham[1604]. Eyton reckons 48 ‘gheld acres’ to the ‘gheld hide,’ but he leaves us utterly at a loss to tell how he came by this computation[1605].
The ploughland and the plough.
Another theory we must examine. It is ingenious and, were it true, would throw much light on a dark corner. It starts from the facts disclosed by the survey of the East Riding of Yorkshire[1606]. In that district, it is said, the number of carucates for geld that there are in any manor (this number we will call a) is usually either equal to, or just twice the number (which we call b) of the ‘lands for one plough,’ or, as we say, teamlands. Further, it can be shown from maps and other modern evidences that the manors in which a = b were manors with two common fields, in other words, were ‘two-course manors,’ while those in which a = 2b were manors with three common fields, in other words were ‘three-course manors.’ The suggested explanation is that while the teamland or ‘land for one plough’ means the amount of land that one plough will till in the course of a year, the ‘carucate for geld’ is the amount of land which one plough tills in one field in the course of a year. Manor X, let us suppose, is a two-course manor; the whole amount of land which a plough will till there in a year will lie in one field; therefore in this case a = b. Manor Y is a three-course manor; in a given year a plough will there till a certain quantity of land, but half its work will have been done in one field, half in another; therefore in this case a = 2b
The Yorkshire carucates.
Now we must own to doubting the possibility of deciding with any certainty from comparatively modern evidence which (if any) of the Yorkshire vills were under a system of three-course culture in the eleventh century. In the year 1086 many of them were lying and for long years had lain waste either in whole or in part. Thus the first group of examples that is put before us as the foundation for a theory consists of 15 manors the sum of whose carucates for geld is 911⁄4 while the sum of the teamlands is 913⁄4. What was the state of these manors in 1086? Three of them were absolutely waste. The recorded population on the others consisted of four priests, one sokemean, eighty-four villeins and twenty-six bordiers; the number of existing teams was 351⁄2; the total valet of the whole fifteen estates was £7. 1s., though they had been worth £72 in King Edward’s day[1607]. It is obvious enough that very little land is really being ploughed, and surely it is a most perilous inference that, when culture comes back to these deserted villages, the old state of things will be reproduced, so that we shall be able to decide which of them had three and which had two fields in the days before the devastation. Further, we can not think that, even for the East Riding of Yorkshire, the figures show as much regularity as has been attributed to them. In the first place, there are admittedly many cases in which neither of the two equations of which we have spoken (a = b or a = 2b) is precisely true. We can only say that they are approximately true. Then there are other cases—too many, as we think, to be treated as exceptional—in which a bears to b some very simple ratio which is neither 1:1 nor yet 2:1; it is 3:2, or 4:3, or 5:3
