Note 604 — Chapter X · THE CONNEXION BETWEEN THE OPEN-FIELD SYSTEM AND SERFDOM OF ENGLAND AND OF THE ROMAN PROVINCES OF GERMANY AND GAUL.

There are two other points which bear upon the Roman connexion with the acre.

(1) If the length of the furrow was to be increased, it would be natural to jump from one well-known measure to another. The stadium, or length of the foot race, was one-eighth of a mile, and was composed of ten of the Greek ἅμμα. The 'furlong' is also the one-eighth of a mile, and contains ten chains. But the stadium contained 625 Roman feet or 600 Greek feet—about 607 English statute feet. How does this comport with its containing 40 rods? The fact is, the rod varied in different provinces, and the Romans adopted probably the rod of the country in measuring the acre. 'Perticas autem juxta loca vel crassitudinem terrarum, prout provincialibus placuit videmus esse dispositas, quasdam decimpedas, quibusdam duos additos pedes, aliquas vero xv. vel x. et vii. pedum diffinitas.'—Pauca de Mensuris, Grom. Vet., Lachmann, &c., p. 371. Forty rods of 10 cubits, or 15 feet each, would equal the 600 feet of the Greek stadium. In fact, the English statute furlong is based upon a rod of 1612 feet. There is also the further fact that the later Agrimensores expressly mention a 'stadialis ager of 625 feet' (Lachmann, Isodorus, p. 368; De Mensuris excerpta, p. 372). So that it seems to be clear that the stadium, like the furlong, was used not only in measuring distances, but also in the division of fields.

(2) We have seen that the acre strips in England were often called 'balks,' because of the ridge of unbroken turf by which they were divided the one from the other. We have further seen that the word 'balk' in Welsh and in English was applied to the pieces of turf left unploughed between the furrows by careless ploughing. There is a Vedic word which has the same meaning.

The Latin word 'scamnum' had precisely this meaning, and also it was applied by the Agrimensores to a piece of land broader than its length. The 'scamnum' of the Roman 'castrum' was the strip 600 feet long and 50 to 80 feet broad—nearly the shape of the English and Bavarian 'acre'—set apart for the 'legati' and 'tribunes.' The fields in a conquered district, instead of being allotted in squares by 'centuriation,' were divided into 'scamna' and 'striga;' and the fields thus divided into pieces broader than their length were called 'agri scamnati,' while those divided into pieces longer than their breadth were called 'agri strigati.' Length was throughout reckoned from north to south; breadth from east to west. Frontinus states that the 'arva publica' in the provinces were cultivated 'more antiquo' on this method of the 'ager per strigas et per scamna divisus et assignatus,' whilst the fields of the 'coloniæ' of Roman citizens or soldiers planted in the conquered districts were 'centuriated.' See Frontinus, lib. i. p. 2, and fig. 3 in the plates, and also fig. 199; and see Rudorff's observations, ii. 290–298. The whole matter is, however, very obscure, and it is difficult to identify the 'ager scamnatus' with the Romano-German open fields. Frontinus was probably not specially acquainted with the latter.
