HUGHES : INGLEBOROUGH. 
In Geology, however, the method does not appear to have been 
systematically tried, though perhaps there is no other subject in 
which this method can be so well applied or be suitable for such 
a large proportion of its students. 
In the following Memoir I have endeavoured to put together 
some notes on one well-defined area in such a manner as it appears 
to me will be most useful for students who wish to avail them- 
selves of this concrete method of teaching the principles of Geology. 
I had no ti-ouble about the selection of a district, for I have 
long arrived at the conclusion that, of all the districts in the 
world that it has fallen to my lot to visit, there is not one to 
compare to Ingleborough and its surroundings for the grandeur 
and variety of its problems, or the clearness and accessibility of 
the evidence upon which we must depend for their solution. 
There are few subjects, moreover, with regard to which this 
term student has so wide a significance as in Geology. Few are 
too young to collect, and to learn to collect intelligently; and few 
too old to follow the progress of this ever-expanding study or to 
carry on the arrangement of and, with experience as a check, to 
speculate upon the significance of facts observed and collections 
amassed in the earlier more vigorous years of life. 
Having regard, then, to the requirements of those who are 
getting up the subject as part of their early education, as well as 
of those who wish to investigate geological phenomena for them- 
selves collectively as Field Clubs or Scientific [Societies, or those 
who rush off alone to take a short holiday in the pursuits of an 
intellectual character in the open air, I oJBfer this small contribu- 
tion, in the hope that it may forward their wishes. 
I have adopted the stratigraphical rather than the geographical 
arrangement, because I think it far more useful to work out the 
details of any district in that manner, and because I feel that 
those who can pay only one visit to each locality must take the 
trouble to get up some of the details beforehand. 
The position of Ingleborough is known to most visitors to 
the North of England. It is the grand terraced mountain along 
whose base you run by rail all the way from Settle to Ingleton
