dip and strike as the underlying Skiddaw slates ; and they extend 

 north-eastward to near Clay Head, where the thin-bedded Skiddaw 

 slates again make their appearance. 



The Skiddaw slates continue along the coast by Garwick to Laxey. 

 They are much contorted, but have a prevailing south-east dip. 

 North of Laxey, also, Skiddaw slates occur having south-east dips. 

 They are well seen on the high-road to Ramsey, about two miles 

 from Laxey, where a considerable cutting has been made through 

 them; and below this cutting, on the coast, they were formerly 

 worked for slating-purposes. 



About half a mile beyond the cutting, and nearer Ramsey, granite 

 is seen on the roadside at a spot called Dhoon ; and north of this, 

 about three miles from Laxey, on the road leading to Maughold 

 Head, the Skiddaw slates again appear, also with south-east dips. 

 A little north of this, and on the same road, at Regnabb, a granite 

 similar to that of Dhoon occurs. Purther north, at Cornah, a hard 

 light-grey rock with no distinct bedding is seen, and at a short 

 distance to the north-west, at Marebreck, haematite has been worked 

 in the Skiddaw slates. About two miles north-east of Marebreck is 

 a bay on the south side of Maughold Head, called Forth Moar ; and 

 in the north side of this bay the Skiddaw slates are well seen, dip- 

 ping north-west at 33°. Here they consist of hard flaggy rocks, 

 grey in colour. On the south side of this small bay the same hard 

 flaggy Skiddaw slates occur with a south-east inclination. An anti- 

 clinal axis appears in the Skiddaw slates of Forth Moar ; and inland 

 for some distance, either along or near this axis, haematite has been 

 wrought.

Maughold Head is composed of Skiddaw slates which dip north- 

 west ; and the same rocks and dip prevail along the road from Maug- 

 hold Head to Ramsey, as far as Ballure. 



At Ramsey, and in the country to the north, no rocks are seen. 

 Boulder-clay being the only substance exposed in this flat country ; 

 but to the west of Ramsey, as far as Sulby, the mountains, which 

 here rise abruptly from the Boulder- clay plain which forms the 

 northern portion of the island, exhibit exposures of the Skiddaw- 

 slate series. 



On the south side of the road leading from Ramsey to Feel, about 

 three miles from Ramsey, is a quarry where road-metal is now 

 worked. The bulk of the rock here is grey hard quartz-rock, with 

 occasional rounded pebbles of quartz imbedded therein. The quartz-
