At first these stones are few and scattered, but they are found to increase in number 

 as one approaches the "Waitotara Eiver. Projecting from the surface are masses of 

 stratified rock, composed of shell-conglomerate : these also havebeeu woruby the wind."

1. "The Red Sandstone Rocks of Peel (Isle of Man)." By 

 William Boyd Dawkins, M.A., D.Sc, F.R.S., F.G.S., Professor of 

 Geology in Owens College (Victoria University), Manchester. 



The Red Sandstone Series, ranging along the coast from Peel to 

 Will's Strand, is faulted into the Ordovician massif of the Isle of 

 Man, It has been referred to the Old Red Sandstone, the Calciferous 

 Sandstone, the basement Carboniferous, and to the Permian. The 

 series consists of red sandstones containing irregular conglomerates 

 and breccias, more or less chemically altered, known in the Lake 

 District as ' Brockram.' Sections at Ballagnane, Creg Malin, and 

 at the Gob and Traie Fogog are described in detail ; the rocks are 

 classified, and their range to the north-east and inland is described. 

 It is pointed out that the rocks are different in many respects from 

 the basement Carboniferous rocks of Langness and elsewhere, and 

 a list of the materials contained in the ' Brockrams ' is given. All 

 these materials have been derived from rocks similar to those which 

 form the Lower Carboniferous Series in the Lake District, with the 

 exception of one or two types which might belong to any other 

 pebble beach. The fossiliferous pebbles in the rocks in question are 

 described, and their fossil contents determined. The whole group 

 of fossils is Lower Carboniferous and Ordivician, and centres mainly 

 in the Carboniferous Limestone. A comparison is instituted with 

 the Permian rocks of Barrowmouth, the Vale of Eden, and elsewhere. 

 The rocks are much sheared and faulted ; the planes of shearing 

 intersect the bedding-planes, and divide the rock into lenticular and 

 diamond-shaped masses, which are scored and slickensided. The 

 earth-movement to which this is due took place in the interval 

 between the latest Palceozoic and earliest Mesozoic deposits. The 

 iron in the rocks was probably derived from the destruction of the 

 Carboniferous shales. 



2. " The Carboniferous, Permian, and Triassic Rocks under the 

 Glacial Drift in the North of the Isle of Man." By William Boyd 

 Dawkins, M.A., D.Sc, F.R.S., F.G.S., Professor of Geology in Owens 

 College (Victoria University), Manchester. 



The whole of the Isle of Man, north of a line drawn due west 

 from Ramsey, is covered with a thick mantle of Glacial Drift. South 

 of this line rises the ice-worn Ordovician massif. Six borings carried 

 out under the advice of the author have elucidated the geological 

 structure of the Drift-covered area. The borings at Lhen Moar, 

 Ballawhane, Knock-e-Doony, Ballaghenny, and two at the Point 

 of Ayre are described in detail, and the rocks classified. The first 

 shows Carboniferous Limestone under Drift ; the second and third, 

 Trias, Permian, Yoredale, and Carboniferous Limestone ; the fourth, 

 Trias, Permian (thin), and Yoredale ; the fifth and sixth, Trias, with 

 gypsum and 76 feet of rock-salt. The rocks all dip in natural order
