[From Isle of Man, Cumming 1848]


All these are lithographs - contrast on the originals is not great and I have attempted to enhance it as much as possible.

The size of all illustrations is 163 x 88 mm with a title below the illustration - they were drawn by Edward Dalamotte, one time art master at the college - most are intended to show the geological structure.

Creggan's Hill is about 1km northwest of the College - today's view would be across Ronaldsway Airport as the hill is just across the road from the terminal

The Creggins Hill from the Silverburn

The Creggins Hill from the Silverburn

I think this might be looking south from near the one-time Cotton mill (now Cumming's flax mill ?) though Cumming's description is I think from a point near today's Ronaldsway halt station where there exists a small foot bridge across the Siverburn

As we pass down the Silverburn, a few hundred yards below the flax-mill,... for about 300 yards till we come to a rustic wooden bridge, and then on the other side (the eastern side) take a seat upon the steps which carry the footpath alongside of the first gate which stops up the bridle-road hence to the Creggins. It is an enchanting station for the lover of scenery, and deeply interesting will it prove to the geologist...

The Creggins Hill in front is of an oblate hemispheroidal shape, and rises to the height of 130 feet above the high-water sea-level. To the north of it is a lower hill of similar shape and character, and the major axis (so to speak) of each of them runs nearly magnetic east and west,.... A flat terrace of gravel fringes round the base of these hills at a bright of twenty-six feet above high-water mark. Yonder group of trees to the eastward, hard by the high road and the Creggins farm-house, have fixed their roots deep into and luxuriated upon this pebbly platform. But the steps on which we are seated are on the level of a still lower platform of fine alluvial sandy loam, upon which the river in its meanderings has made great inroads, and deposited in its stead a considerable quantity of montane detritus, boulders, gravel and sand. In the corner of the field on our right, on the opposite side of the road from the cottage, is a patch of turfy ground, from underneath which, in a whitish marl, have been turned up some remains of Cervus megaceros. The drift-gravel directly before us is worn into cavities, presenting all the appearance of a low sea cliff exposed to the action of breakers.

The figure in the arch would appear to be a geologist!

A further set of Plates had a description section following the contents page


1. General Map of the Isle of Man, coloured geologically, with a Table of Signs and Colours. The outer dotted line represents the coast at low-water; the continuous coast-line is high-water-mark.

2. General Section across the south-western part of the Island from Lhergydhoo, north-east of Peel, across the granite boss on South Barrule to Langness Point, south-east of Castletown.


Geological Map of the Limestone Basin and other parts of the southern district of the Island, as it is supposed they would appear if denuded of the gravels, sands and clays of the Tertiary period.

This Map exhibits the relations of the Carboniferous limestone to the Old Red sandstone formation and the great Schistose series of the Island, and the intersection and contortion of this area by igneous rocks.


In this Map we have included the Tertiary formations denuded in Plate II. The different shades of yellow and green represent the Boulder-clay, the Drift-gravel and the newest Marine and Freshwater alluvium with raised beaches, and exhibit the formation of long valleys of denudation during a period of elevation of the Island, and the manner in which some portions of the Tertiary series have been preserved by the peculiar arrangement of the palaeozoic rocks.

Map derived from Durham/Speed 1595/1611 map


Map of the Isle of Man in 1595, performed by Thomas Durham, as given in Camden's ' Britannia,' Speed's 'Chronicles,' Chaloner's History,' and Bleau's 'Atlas,' published at Amsterdam. It exhibits ancient lakes both in the north and south of the Island, which arc now drained.


1. Ground Plan of a portion of Poolvash Bay, as seen at low-water at the n.outh of the streamlet which flows from Balladoole into the sea. It exhibits a remarkable series of Bosses on the surface of the limestone, caused apparently by the intrusion of trap rocks, which are abundant in that neighbourhood.

2. Section North and South magnetic in the above Plan across the Bosses, snowing the undulations.


1. Ground Plan (coloured geologically) exhibiting the details of the Coast from Ronaldsway, near Derby Haven, to Coshnahawin, at the mouth of the Santon-burn, and marking the position of the faults, cracks and axes of disturbance connected with the elevation of the Brough, and the formation of a series of Bosses in connection with trap dykes along the axes of disturbance.

Sections 1, 2, 3 and 4 to the above Plan, are intended to illustrate the elevation of the Brough at the mouth of the Santon-burn, and the manner in which the Bosses may be supposed to have been formed by the intrusion of trap amongst the pebbles of the old red conglomerate. The letters of reference, O P, A T, S R, Q K, shore the direction of the lines of section.


Various Sections exhibiting the arrangement of the different formations in the South of the Island, the intersection of the area by dykes of trap and porphyritic greenstone, and the consequent faults and undulations of the surface.

1. Section from Brada Head to Coshnahawin, showing the denudation of the older rocks after the formation of the great faults and undulations, the deposit of the tertiary gravels, sands and boulder-clays on the abraded surface, and the formation of alluvial basins by the action of the sea, during a still subsequent elevation of this area.

2 & 3. Sections from the Mull Hills to Langnes, and from Black Hill to Scarlet Head, illustrating the formation of the stratified trap-tuff with the included Posidonian schist.

4. Ground Plan, showing the ramifications of trap when traversing beds of the Old Red conglomerate on the eastern side of Castletown Bay. See page 84 of this work.

5. Section near the Stack of Scarlet, exhibiting the contortion of the limestone and the trap-tuff by a second volcanic disturbance.

6. Section at the Calf of Man, showing the remarkable position of a mass of stratified gravel and sand at an elevation of nearly 400 feet above the present sea-level. See page 155 of the present work.


l. Section in the North of the Island from the mountain range near Ballaugh to Jurby Point, showing the formation of the great Curragh and the freshwater marl basins, in which have been found the remains of the great Irish Elk.

N.B. The arrangement of the limestone and Old Red conglomerate is theoretical, as detailed in the body of the work, page 210.

2. Section through Hango Hill and King William's College to the Creggins, exhibiting the Cliff of Boulder Clay and the arrangement of the drift-gravel and alluvium.

3. Section at the mouth of Glen Willan, near Kirk Michael, showing a valley of denudation in the drift-gravel and boulder clay, with terraces of alluvium at different levels.
