The principal enclosure is an irregular circle, or rather a square 

 with the angles rounded off, of about 250 feet in diameter. Subsidiary 

 to this, there is on the western side an annexe of the same general out- 

 line, of about 180 feet in diameter, showing much the same relation 

 to the principal enclosure as that described at Relig-na-ree. Counting 

 this as one division in the general ground-plan, there appears to have 

 been here, as at Relig-na-ree, a five-fold partition of the enclosed space. 

 Each division contains the remains of tumuli, the more prominent of 

 which only are indicated on the plan : —

Ground-plan of Cemetery at Usnach. 

 [Ord. Map, Westm., sheet 24.] 



Some of these appear to have been erected on the intersection of the 

 mounds of demarcation, and all have been opened. In the western 

 division, the mouth of a cave has been exposed, and other holes injihe 

 surface show where the roofing stones of the passage have fallen in. 



All the constructions, so far as visible, are of the same rude 

 character as at E-athcroghan ; the interments are below the surface. 

 There is no appearance of stone cutting or of decorative work of any 

 kind, and no trace, so far as I could observe, of any Christian 

 emblem. 



The general aspect of this cemetery seems hardly reconcil- 

 able with the suggestion of such monuments as those of Slieve-na- 

 Calliagh, not to speak of the New Grange group, having proceeded 

 from the same race of builders, or having been cotemporaneously 

 erected for similar purposes.
