HUGHES : INGLEBOROUGH. 
As we stand on the top of the highest Carboniferous beds 
of Ingleborough, we may ask how much is gone from above, 
and how much that represents what once extended over Ingle- 
borough has been thrown down and Hes under the drift-covered 
countr}^ below us as we look out seaward ? 
When we are speculating upon the age of the earth move- 
ments of which we have direct evidence in this district, we must 
bear in mind the Basement Beds containing corals, which appear 
to have been broken and overthrown and shifted from their 
original place, with the great stones to which they had been 
attached, while close by we find them still undisturbed in the 
position in which they grew. Xow these corals are not things 
that sprung up like mushrooms in a night ; they are large masses 
of slow growth by budding, and the manner in which they now 
occur is quite consistent with the view that there v/ere recur- 
rences of changes of current and disturbances of sediment, such 
as might be supposed to accompany earth movements. 
Here and there throughout the limestones, beds are found 
made up of angular fragments, which are not due to brecciation 
in place, and yet cannot have been far transported, while the 
broken corals and other fossils which occur in them suggest the 
breaking up of recently formed deposits. An interesting paper 
bearing upon this q uestion has recently appeared in the Bulletin 
of the Soc. Beige de Geologic.* 
No such thing is known, or probable, as that there should 
be an uplift of 5,000 feet or so a un seul jet, as Elie de Beaumont 
would have said ; and, if the relative displacement was gradual, 
that must have affected the character of the formations on the 
north and south side of the Craven Faults, which were the axis 
of the movement. Did that movement commence in Carboni- 
ferous times, and through what geological ages did it extend ? 
Here surely is question of la haute geologie worthy of a place 
in your programme of work. 
Let us now turn round and look inland. We see gently 
rounded hills moulded out of the old Sea Plain. Sometimes,
