The identification of Duma na Bo is a problem of some difficulty. Duma 

 na nGiall is conspicuous enough. West of it Petrie marks on his map, and 

 describes, 1 a mound 6 feet high and 40 feet in diameter at the base, which 

 he calls Duma na E N withstanding the most careful search neither 

 Mr. Westropp nor I could discover the .slightest trace of it. I find it hard 

 ■elieve in the total disappearance of so large an eaithwork within the 

 past eighty ; ggers vould have left trace of their

 It has escaped notice that there is a mound incorporated with the north-
