Part 46

It is very probable that in England this rule prevailed at a remote time. Throughout the middle ages and on to our own day there have been many 'acres' in England which swerved markedly from what had become the statutory type, and in some cases a pattern divergent from the statutory pattern became 'customary' in a district. But apparently these customary acres commonly agree with the royal standard in involving the equation: 1 acre = 4 perches x 40 perches[1258]. In Domesday Book and thence onwards the common Latin for _furlong_ is _quarentina_, and this tells us of furrows that are forty perches long. It is when we ask for the number of feet in a perch that we begin to get various answers, and very various they are. The statutory number, the ugly 16·5, looks like a compromise[1259] between 15 and 18, both of which numbers seem to have been common in England and elsewhere. This is the royal equation in the thirteenth century; it has been found near the middle of the twelfth[1260]; more at present we cannot say. Short perches and small acres have been very common in the south of England. In 1820 some information about the customary acre was collected[1261]:--In Bedfordshire it was 'sometimes 2 roods.' In Dorsetshire 'generally 134 [instead of 160] perches.' In Hampshire, 'from 107 to 120 perches, but sometimes 180,' In Herefordshire, 'two-thirds of a statute acre,' but 'of wood, an acre and three-fifths or 256 perches.' In Worcestershire, 'sometimes 132 or 141 perches.' In Sussex, '107, 110, 120, 130 or 212 perches'; '_short acre_, 100 or 120 perches'; '_forest acre_, 180 perches,' Then as to rods, the 'lug or goad' of Dorsetshire had 15 ft. 1 in.; in Hertfordshire, 20 feet; in Wiltshire, 15 or 16-1/2 or 18. The wide prevalence of rods of 15 feet can not be doubted, and it seems possible that rods with as few as 12 feet have been in use[1262]. An acre raised from a 12 foot rod would, if feet were invariable, be little more than half our modern statute acre. Nowhere do we see any sure trace of a rod so short as the Roman _pertica_ of ten _pedes_, though the scribes of the land-books will give the name _pertica_ to the English _gyrd_[1263].

[Large acres.]

In northern districts the 'customary' acre grows larger. In Lincolnshire it is said to be '5 roods, particularly for copyhold land'; but small acres were known there also[1264]. In Staffordshire, 'nearly 2-1/4 acres.' In Cheshire, 'formerly and still in some places 10,240 square yards' (pointing to a rod of 24 feet). In Westmoreland, '6760 square yards' (pointing to a rod of 19-1/2 feet), also the so-called 'Irish acre' of 7840 square yards (pointing to a rod of 21 feet). There is much evidence that rods of 20 and 21 feet were often used in Yorkshire and Derbyshire. Rods of 18, 19-1/2, 21, 22-1/2 and 24 feet were known in Lancashire. A writer of the thirteenth century speaks as if rods of 16, 18, 20, 22 and 24 feet were in common use, and mentions none shorter[1265]. As just said, the Irish plantation acre was founded on a rod of 21 feet. The Scotch acre also is larger than the English; it would contain about 6150·4 instead of 4840 of our square yards; it is formed from a rod of 6 Scotch ells. On the other hand, the acres which have prevailed in Wales seem to be small; one type had 4320 of our square yards, another 3240.

[Anglo-Saxon rods and acres.]

There has been variety enough. Even if the limits of variation are given by rods of 12 and 24 feet, this will enable one acre to be four times as large as another. Whether before the twelfth century there was anything that we ought to call a standard rod, a royal rod for all England, must be very doubtful. In royal and other land-books references are made to furlongs, to acre-breadths, to yards or rods or perches, and to feet as to known measures of length[1266], but whether a kingly gift is always measured by a kingly rod we do not know. The Carolingian emperors endeavoured to impose a rod upon their dominions; it seems to have been considerably shorter than our statute perch[1267]. In this province we need not expect many Norman novelties. We see from Domesday Book that the Frenchmen introduced the ancient Gallic _arpentum_[1268] as a measure for vineyards[1269]; but most of the vines were of their own planting, and the mere fact that they used this measure only for the vineyards seems to tell us that they were content with English rods and English acres[1270]. In Normandy the perches seem to have ranged upwards from 16 to 25 feet[1271]; so that 16·5 would not have hit the average. On the whole, our perch seems to speak of a king whose interests and estates lay in southern England and who struck a mean between 15 and 18. Whoever he was, we owe him no thanks for the 'undecimal' element that taints our system[1272].

[Customary acres and forest acres.]

But we must be cautious in drawing inferences from loose reports about 'customary' measures. Village maps and village fields have yet to be seriously studied. We may in the meanwhile doubt whether in some districts to which the largest acres are ascribed, such acres are normal or are drawn in the oldest villages. We may suspect them of being 'forest acres.' If once a good many of these abnormal units are distributed in a district, they will by their very peculiarity attract more than their fair share of attention and will be spoken of as characteristic of that district. In Germany, as well as in England, we find forest acres which are much larger than common acres and are meted by a rod which is longer than the common rod[1273]. Possibly men have found a long rod convenient when they have large spaces to measure, but we fancy that the true explanation would illustrate the influence exercised by taxation on systems of measurement. Some scheme of allotment or colonization is being framed; an equal tribute is to be reserved from the allotted acres. If, however, there is uncleared woodland to be distributed, rude equity, instead of changing the tribute on the acre, changes the acre's size and uses a long rod for land that can not at once be tilled[1274]. Also fields that were plotted out by Normans were likely to have large acres, and as the perches of Normandy seem to have been longer than most of the perches that were used in France, we may perhaps infer that the Scandinavian rods were long and find in them an explanation of the big acres of northern England. But at present such inferences would be precarious.

[The acre and the day's work.]

Whether in its origin the land-measuring rod is a mere representative of a certain number of feet or is some instrument useful for other purposes seems to be dubious. One of the names that it has borne in English is _goad_; but most of our rods would be extravagantly long goads[1275]. Possibly the width of four oxen yoked abreast has exercised some influence upon its length[1276]. When a rod had once found acceptance, it must speedily have begun to convert that 'time-labour-unit,' the acre, into a measured space. Already in the land-books we read of acres of meadow[1277]; this is no longer a contradiction in terms. Still there can be no doubt that our acre, like the _jurnale_, _Tagwerk_, _Morgen_ of the Continent, has at its root the tract that can be ploughed in a day, or in a forenoon:--in the afternoon the oxen must go to the pasture[1278]. Now, when compared with their foreign cousins, our statute perch is a long rod and our statute acre is a decidedly large 'day-work-unit[1279].' It seems to tell of plentiful land, sparse population and poor husbandry. This is of some importance. There is a good deal of evidence pointing to the conclusion that, whereas in the oldest days men really ploughed an acre in a forenoon, the current of agricultural progress made for a while towards the diminution of the space that was covered by a day's labour. In Ælfric's dialogue the ploughman complains that each day he must till 'a full acre or more[1280].' His successor, the poetic Piers, had only a half-acre to plough[1281]. In monastic cartularies which come from southern counties, where we have no reason to suspect exceptionally large acres, the villein seems often to plough less than an acre[1282]. Then that enlightened agriculturist, Walter of Henley, enters upon a long argument to prove to his readers that you really can plough seven-eighths of an acre in a forenoon, and even a whole acre if you are but engaged in that light kind of ploughing which does for a second fallowing[1283]. Five centuries later another enlightened agriculturist, Arthur Young, discovered that 'from North Leach, through Gloucestershire, Monmouthshire, and Glamorganshire, light and middling turnip-land etc.' was being ploughed at the rate of half an acre to one acre a day by teams of 'eight oxen; never less than six; or four and two horses.' This, he says, was being done 'merely in compliance with the obstinacy of the low people,' for 'the labourers will not touch a plough without the usual number of beasts in it[1284]'. Mr Young could not tell us of 'these vile remnants of barbarity without a great degree of disgust[1285]'. But we are grateful. We see that an acre of light land was the maximum that these 'low people' with their eight oxen would plough in a day, and we take it that at one time the voice of reforming science had urged men to diminish the area ploughed in a given time, to plough deeper and to draw their furrows closer. The old tradition was probably well content with a furrow for every foot. Walter of Henley proposed to put six additional furrows into the acre[1286]. Hereafter we shall see that some of the statistics given by Domesday Book fall in with the suggestion that we are here making. Also we may see on our maps that the strip which a man has in one place is very often not an acre but a half-acre. Now, in days when men really ploughed an acre at a stretch, such an arrangement would have involved a waste of time, since, when the morning's work was half done, the plough would be removed from one 'shot' to another[1287].

[The real acres in the fields.]

At length we reach the fields, and at once we learn that there is something unreal in all our talk of acre and half-acre strips. In passing we may observe that some of our English meadows which show by their 'beds' that they were not always meadows, seem to show also that the boundaries of the strips were not drawn by straight rods, but were drawn by the plough. The beds are not straight, but slightly sinuous, and such, it is said, is the natural course of the old plough; it swerves to the left, and this tendency is then corrected by those who guide it[1288]. But, apart from this, land refuses to be cut into parallelograms each of which is 40 rods long and 4 wide. In other words, the 'real acres' in an open field diverge widely from the ideal acre that was in the minds of those who made them.

[The 'shots.']

Let us recall a few features of the common field, though they will be familiar to all who have read Mr Seebohm's book[1289]. A natural limit to the length of the furrow is set by the endurance of oxen. From this it follows that even if the surface that lies open is perfectly level and practically limitless, it will none the less be broken up into what our Latin documents call _culturae_[1290]. The _cultura_ is a set of contiguous and parallel acre-strips; it tends to be a rude parallelogram; two of its sides will be each a furlong ('furrowlong') in length, while the length of the other sides will vary from case to case. We commonly find that every great field (_campus_) is divided into divers _culturae_, each of which has its own name. The commonest English equivalent for the word _cultura_ seems to have been _furlong_, and this use of _furlong_ was very natural; but, as we require that term for another purpose, we will call the _cultura_ a _shot_. So large were the fields, that the annual value of an acre in one shot would sometimes be eight times greater than that of an acre in another shot[1291]. To such differences our ancestors were keenly alive. Hence the dispersion of the strips which constitute a single tenement.

[Delimitation of shots.]

But to make 'shots' which should be rectangular and just 40 feet long was often impossible. Even if the surface of the field were flat, its boundaries were the irregular curves drawn by streams and mounds. In order to economize space, shots running at right angles to other shots were introduced, and of necessity some furlongs were longer than others. If, however, as was often the case, men were laying out their fields among the folds of the hills, their acres would be yet more irregular both in size and in shape. They would be compelled to make very small shots, and the various furrows if 'produced' (in the geometer's sense of that word) would cut each other at all imaginable angles. On the maps we may still see them struggling with these difficulties, drawing as many rectilinear shots as may be and then compelled to parcel out as best they can the irregularly shaped patches that remain. And then we see that even these patches have been allotted either as acres or as half-acres.

[The real and the ideal acre.]

Therefore, when we are dealing with medieval documents, we have always to remember that besides ideal acres there were real acres which were mapped out on the surface of the earth, and that a plot will be, and rightly may be, called an acre though its size is not that of any ideal acre. To tell a man that one of these acre-strips was not an acre because it was too small would at one time have been like telling him that his foot was no foot because it fell short of twelve inches. This point is made very plain by some of the beautiful estate maps edited by Mr Mowat[1292]. We have a map of 'the village of Whitehill in the parishe of Tackley in the countye Oxon., the moitye or one halfe whereof belongeth to the presidente and schollers of Corpus christi colledge in the universitye of Oxon., the other moitye unto Edwarde Standerd yeoman the particulars whereof soe far as knowne doe plainelye appeare in the platte and those which are unknowne, as wastes comons and lotte meadowes are equallye divided betweene them, drawne in November anno domini 1605, regni regis Iacobi iijº.' We see four great fields divided first into shots and then into strips. Each strip on the map bears an inscription assigning it either to the college or to Mr Standerd, and with great regularity the strips are assigned to the college and to Standerd alternately. Then on each strip is set its 'estimated' content, and on each strip of the college land is also set its true content. Thus looking at one particular shot in the South Field we read:

ij. ac. coll. 1. 1. 36 Edw. Stand. ij. ac. ij. ac. coll. 1. 2. 2 Edw. Stand. ij. ac. ij. ac. coll. 1. 2. 2 Edw. Stand. ij. ac. ij. ac. coll. 1. 0. 39.

This means that, going along this shot, we first come to a two-acre-strip of college land containing by admeasurement 1 A. 1 R. 36 P.; next to a two-acre strip of Standerd's land, which the surveyor, who was making the map for the college, was not at pains to measure; then to a two-acre strip of college land containing 1 A. 2 R. 2 P.:--and so forth. Then in the margin of the map has been set 'A note of the contentes of the landes in Whitehille belonginge to the colledge.' It tells us how 'theire groundes in the West Fielde by estimation 80 acres doe conteine by statute measure 48 A. 2 R. 24 P.' The other fields we may deal with in a table

A. A. R. P. East Field estimation 75 measure 51 1 25 Middle Field 58 39 3 36 South Field 103 59 2 13

It will be seen at once that the discrepancy between the two sets of figures is not to be fully explained by the supposition that at Whitehill men had measured land by measures differing from our statutory standards[1293]. The size of a 'two-acres' (and the land in this instance had been divided chiefly into 'two-acres') varied not only from field to field and shot to shot, but within one and the same shot. Each two-acre strip has an equal breadth, but the curving boundaries of the fields make some strips longer than others[1294].

[Varying size of the acres.]

We turn to the admirable maps of Heyford in Oxfordshire designed in 1606. Here the land is divided among many occupiers and cut up into a vast number of strips, to each of which is assigned its 'estimated' and its measured content. Thus we read:--

dim. ac. Jo. Sheres 1. 18 dim. ac. Ric. Elkins 1. 18 dim. ac. Jo. Merry 1. 18.

In this part of this shot a 'half-acre' contains 1 R. 18 P. Some of the shots in this village have fairly straight and rectangular boundaries, so that we may, for example, find that many successive 'half-acres' contain 1 R. 18 P. But then if we pass to the next shot we shall find 1 R. 28 P. in the 'half-acre,' while in a third shot we shall find but 1 R. 8 P. Yet every strip of land is a 'half-acre' or an 'acre' or a 'acre and a half' or a 'two acres' or a 'three acres.' We see further that when 'acres' occur among 'half-acres' the strips vary in breadth but not in length.

On a map of Roxton made in 1768 we have the same thing written out in English words. Thus:--

Eliz. Gardner a half 0. 1. 32 Carpenter a half 0. 1. 32 Harris an acre 0. 3. 24 Carpenter a half 0. 1. 32 Jam. Gardner an acre 0. 3. 24 Makepace a half 0. 1. 34

The result of all this is that anyone who lives in a village knows how many 'acres' its fields contain. He has not to measure anything; he has only to count strips, for he is not likely to confuse 'acres' with 'half-acres' and that is the only mistake that he could make.

[Irregular length of acres.]

If a shot had a curved boundary, little or no pains seem to have been taken to equalize the strips that lay within it by making additional width serve as a compensation for deficient length. The width of the so-called acre remained approximately constant while its length varied. Thus, to take an example from the map of Heyford, we see a shot which is bounded on the one side by a straight line and on the other by a curving road. At one end of it the acre contains 2 R. 8 P.; this increases to 2 R. 30 P.; then slowly decreases until it has fallen as low as 1 R. 36 P., and then again rises to 2 R. 2 P. When they were dividing the field, men attempted to map out shots in which approximately equal areas could be constructed; but, when a shot was once delimited, then all the acres in it were made equally broad, while their length could not but vary, except in the rare case in which the shot was a true rectangle[1295].

[The selions or beds.]

It is probable that the whole system was made yet more visible by the practice of ploughing the land into 'beds' or ridges, which has but recently fallen out of use. In our Latin documents these ridges appear as selions (_seliones_). In English they were called 'lands,' for the French _sillon_ struck no root in our language. Anyone who has walked through English grass fields will know what they looked like, for they triumph over time and change[1296]. Now it would seem that a fairly common usage made four selions in each acre[1297]; in other words, each acre-strip was divided longitudinally into four waves, so that the distance from crest to crest or trough to trough was a perch in length. Where this usage obtained, you could tell how many acres a shot or field contained by merely observing the undulations of the surface. Even if, as was often the case, the number of selions in the acre was not four, still the number that went to an acre of a given shot would be known, and a man might argue that a strip was an acre because in crossing it he traversed three or six terrestrial waves[1298].

[Acres divided lengthwise.]

If we look at old maps, we soon see that when an acre was divided, it was always divided by a line that was parallel, not to its short ends, but to its long sides. No one would think of dividing it in any other fashion. Suppose that you bisected it by bisecting its long sides, you would force each owner of a half-acre to turn his plough as often as if he had a whole acre. Besides, you would have uneconomical furrows; the oxen would be stopped before they had traversed what was regarded as the natural distance for beasts to go. Divide your acre into two long strips, then your folk and beasts can plough in the good old way. Hence it follows that when men think of dividing an acre they speak only of its breadth. Hence it follows that the quarter of an acre is a 'rood' or 'yard[1299]' or _virga_ or _virgata_ of land. Its width is a rod or land-yard, and its length--but there is no need to speak of its length[1300].

[The virgate.]

How then does it happen that these terms 'virgate' and 'yard of land,' though given to a quarter of an acre, are yet more commonly given to a much larger quantity containing 30 acres or thereabouts? The explanation is simple. The typical tenement is a hide. If you give a man a quarter of a hide (an equitable quarter, equal in value as well as extent to every remaining quarter) you do this by giving him a quarter of every acre in the hide. You give him a rood, a yard, a _virga_[1301], a _virgata_ in every acre, and therefore a rood, a yard, a _virga_, a _virgata_ of a typical tenement[1302].

[The double meaning of a yard.]
