Lavatre and not Concangium. But reversing the order, their route 

 would pass eastwards through Concangium, and hence not south- 

 ward again, but northward to the Wall. 



Thus the stations that are put after Braboniacum must be looked 

 for after Concangium, and in connection with the east end of the 

 Wall. Maglova and Mag^ may well be supposed to guard the 

 valley of the Tees, the possession of which was an absolute 

 necessity as an adjunct to the road over Stainmore. Then at 

 Longovicum (Lanchester), we are in direct communication with 

 the east end of the Wall at South Shields, via Epiacum (Chester- 

 le-Street), and by another arm to the central portion of the Wall 

 via Derventio (Ebchester-on-Derwent). 



At Braboniaaa/i, at least three arms run to the Wall : — 

 (i) Via the Maiden Way, reaching the central portion of the Wall 

 at Magna (Carvoran). (2) Via the second Iter to Luguvallum 

 (Carlisle). (3) Via Whitbarrow to Old Carlisle and Keswick. 



Granted then that we have shewn a perfect sequence of places, 

 so far as the thirteen stations just named are concerned, it seems 

 but natural that the same plan should be followed with regard to 

 the remaining stations "perlineam valli." 



Before we can fairly discuss the next part of the question, we 

 shall have to decide (i) that only eighteen are on the Wall, and 

 (2) which five are not actually on the Wall. Antiquarians are 

 tolerably in accord in placing eighteen as the number; and it 

 seems only reasonable that Timnocehwt, the eighteenth station, 

 should be on the sea coast, seeing that its garrison, according to 

 the Notitia, was the ist Cohort of the^lia Classica, i.e., a Cohort 

 of Marines. 



Following then the order as given, this station must have been 

 on the west coast, and hence at either Bowness or Skinburness. 



The Rev. W. Lytteil, writing to me on this point, says : — " I regard 

 Tunnocelum as derived from the Gaelic (or Celtic) dun a' chaoil, 

 signifying 'the fort of the firth — the fortress of the strait' This 

 is to be preferred to dun na caoile, meaning the 'fort of the narrows,' 

 literally 'the fort of the narrowness, or waist.' The somewhat 

 narrow mouth of the Gareloch (about opposite to Greenock) is
