with crossing the line of the Way almost at right angles. This 

 and the Devil's Ditch an i 90 -imilar ti one another thai they 

 may be described together. Both Ditches are furnished with 

 a mound or rampart on their eastern side; so that, if defensive 

 works, their makers must have anticipated attacks from the 

 west. Both run from the fenland in the neighbourhood of 

 the Cam, and after crossing the open country between fen 

 and forest, end in the latter, the Devil's Dyke crossing New- 

 market Heatli from the fens at Heche to the woodlands near 

 Wood Ditton (Ditch-town); while the Fleam Dyke is trace- 

 able from near Fen Ditton (Ditch-town) to the wooded country 

 near Balsham. But there are some differences to he noted 

 between these two great Dykes: for the Devil's Dyk 

 straight throughout, while the Fleam Dyke is sinuous in cor- 

 respondence with the requirements of the ground; and 

 whereas the former is continuous throughout its length, the 

 Fleam Dyke is interrupted at Wilbraham Fen (whicli rendered 

 a special dyke unnecessary), and again shortly before its ter- 

 mination at Balsham. To the foregoing must be added 

 mention of two other ditches, though these are of much 

 smaller dimensions. The Pampisford Ditch, about a mile and 

 three-quarters in length, is to be seen at Brent-Ditch End at 

 Pampisford (eight miles from Cambridge) and it crosses the 

 Icknield Way just as the three other ditches do ; there is 

 some uncertainty as to which side of the ditch was occupied 

 by the rampart. Further to the south, and also crossing tin 1 

 Icknield Way, is the Brand or Heydon Ditch, two miles in 

 length, with ramparts on the eastern side. 



It is not possible to enter into a detailed description 

 of these remarkable remains, but it must suffice to insist upon 

 their impressive character, especially in the case of the larger 

 examples, consisting as they do of the combination of hank 

 and ditch traceable for miles across the county. IN' or is it 

 possible to discuss their significance. From the Heydon 

 Ditch comes some evidence to shew that the L-knield Wax- 

 existed before the trenches were cut. Though popularly sup-
