SOME SUNKEN TRACK-WAYS NEAR SAFFRON WALDEN. 243 developed in the course of centuries into one of these deep sunken track-ways. Finally, what is the age of these sunken track-ways ? This is a question it is not easy to answer with precision. There has been, of course, a certain amount of pack-horse traffic from extremely early times, and it is difficult to fix any definite limit to the possible antiquity of these track-ways, which appear to have been caused by that traffic. In the case of the track coming from Newport, however, there does seem to be some evidence as to its age. Thus, there can be little or no reasonable doubt that it is the "Short Ditch" which gave name to the Manor of Shortgrove, in which it is situated ; for, in Domesday Book,8 that manor appears as "Scortegrave" and as "Sortegrave" (the latter evidently a scribal error). This name is obviously derived from the O.E. words scort, short, and graef, a ditch or trench.9 The track-way must, therefore, have been already in existence at least as early as Saxon times (say, in the fifth, sixth or seventh century), when our manors were first organised.10 It may be, indeed, of much earlier date ; for it has the appear- ance or having once been an early tribal boundary, as well as (or before it was) a track way ; and the existence on its southern side of two parallel banks, suggests that it may have been intended to defend the country lying to the south of it from some enemy threatening from the north. However all this may be, we may assume, that these narrow sunken track-ways continued to be used until the period when travel on horseback and horse back transport of merchandise gave place, in the Middle Ages, to travel and transport by means of wheeled vehicles. 8 Sec V.C.H.
