SCOTLAND AND IRELAND 



slabs, the outer being still beneath the cover- 

 slabs. On the upper surface of the covers 

 are several small cup-shaped hollows, some of 

 which at least have been produced artificially. 



These wedge-shaped structures are of remark- 

 able interest, for exactly the same broadening 

 of the west end is found in Scandinavia, in the 

 Hiinenbetter of Holland, in the corridor-tombs of 

 Portugal, and in the dolmens of the Deccan in 

 India. 



In some Irish tombs the corridor leads to a well- 

 defined chamber. In a curious tomb at Carrickard, 

 Sligo, the chamber was rectangular and lay across 

 the end of the corridor in such a way as to form 

 a T. The whole seems to have been covered with 

 an oval mound. In another at Highwood in the 

 same count}' a long corridor joins two small 

 circular chambers, the total length being 44 feet. 

 The corridor was once divided into four sections 

 by cross-slabs. The cairn which covered this 

 tomb was triangular in form. 



In the county of Meath, in the parish of Lough 

 Crew, is a remarkable series of stone cairns ex- 

 tending for three miles along the Slieve-na- 

 Callighe Hills. These cairns conceal chamber- 

 tombs. The cairns themselves are roughly 

 circular, and the largest have a circle of upright 

 blocks round the base. The chambers are built 

 ofjjupright slabs and are roofed by corbelling.
