On other parts of the Wall Dr. Macdonald has gained further successes. Evidence seems to be coming out as to the hitherto missing forts of Kirkintilloch and Inveravon. More details have been secured of the fort at Mumrills--fully 4-1/2 acres in area and walled with earth, not with the turf or stone employed in the ramparts of the other forts of the Wall. The line of the Wall from Falkirk to Inveravon, a distance of four miles, has also been traced; it proved to be built of earth and clay, not of the turf used in the Wall westwards. Dr. Macdonald suggests that the eastern section of the Wall lay through heavily wooded country, where turf was naturally awanting.
(iii) _Traprain Law._ Very interesting, too, are the preliminary results secured by Mr. A. O. Curie on Traprain Law. This is an isolated hill in Haddingtonshire, some twenty miles east of Edinburgh, on the Whittingehame estate of Mr. Arthur Balfour. Legends cluster round it--of varying antiquity. It itself shows two distinct lines of fortification, one probably much older than the other, enclosing some 60 acres. The area excavated in 1914 was a tiny piece, about 30 yards square; the results were most promising. Five levels of stratification could be distinguished. The lowest and earliest yielded small objects of native work and Roman potsherds of the late first century: higher up, Roman coins and pottery of the second century appeared, and in the top level, Roman potsherds assigned to the fourth century. One Roman potsherd, from a second-century level, bore three Roman letters IRI, the meaning of which is likely to remain obscure. As the inscribed surface came from the inside of an urn, the writing must have been done after the pot was broken, and presumably on the hill itself. Among the native finds were stone and clay moulds for casting metal objects. The site, on a whole, seems to be native rather than Roman; it may be our first clue to the character of native _oppida_ in northern Britain under Roman rule; its excavation is eminently worth pursuing.
(iv) _Northumberland, Hadrian's Wall._ On Hadrian's Wall no excavations have been carried out. But at Chesterholm two inscribed altars were found in the summer. One was dedicated to Juppiter Optimus Maximus; the rest of the lettering was illegible. The other, dedicated to Vulcan on behalf of the Divinity of the Imperial House by the people of the locality, possesses much interest. The dedicators describe themselves as _vicani Vindolandenses_, and thus give proof that the civilians living outside the fort at Chesterholm formed a _vicus_ or something that could plausibly be described as such; further, they teach the proper name of the place, which we have been wont to call Vindolana.
