EFFECTS OF 
of the millstone grit ; but, besides its connexion with the Craven 
fault, there are other points of view which have determined me to 
place it here. The most important of these is the occurrence of red 
sandstone over the coal. My own knowledge of this curious coal- 
field, obtained during my residence at Kirby Lonsdale, was not con- 
siderable, but for this full amends has been made by the ready aid 
of Mr. Hodgson of Lancaster, an eminent Surveyor, joint proprietor 
of the Burton coal tract, who has had the kindness to furnish me 
with accurate sections, and valuable observations concerning this coal- 
field and its relations to many coal deposits of the millstone orit 
series in North Lancashire, with which his professional and geologi- 
cal researches had made him well acquainted. 
The situation of the Ingleton coal, in itself singular, is rendered 
doubly interesting to the geologist from its complete analogy to that 
of the Hartley burn coalfield on the south Tyne. Both of these 
little coal deposits are far detached from the large coal tracts to which 
they appear most related ; both extend from east to west : both lie 
at the foot of a lofty escarpment of rocks much older than them- 
selves ; both rest on those same rocks sunk perpendicularly more 
than two thousand feet by dislocation. Certainly the first view of 
these situations would lead to the impression that the dislocations 
had happened before the deposition of the coal, for not a span breadth 
of deposits of the same age lies on any hill of the whole Penine 
region from Lonsdale to the valley of the Tyne, from Wharfedale 
to the Tees.— More exact inquiry reverses this opinion, and leads to 
important reflections on the cause of this extremely limited deposition 
of coal before the production of the Craven fault, or its almost total 
removal afterwards. 
The section (No. 1,) from Burn moor in Bolland to InMeboroimh 
crossing the Ingleton and Burton coalfield, will sufficiently indicate the 
leading features of the deposits. It is not properly a basin, for its 
planes of stratification have scarcely any other dip than to the north- 
east ; not according to their original position, but under the influence
