the characteristics of a common fault , for here the strata of different inclinations 
seemed to he morticed together as if they had been dovetailed by a joiner. He 
stated that what he had brought forward was not hypothesis, but the result of 
intimate acquaintance with the country, and he had brought forward the particular 
points adverted to because they were very remarkable. But how the dislocations 
took place, and the discussion of the why and the wherefore, he would leave to 
better judges to consider. 
Mr. Morton said, both gentlemen seemed to agree as to the effect produced* 
But the question was whether it had been by a vertical or a lateral movement? 
He thought Mr. Thorp’s argument for the vertical movement conclusive, and 
even the sections served to show beyond a doubt that the movement must have 
been upward. 
Mr. Hartop explained that he did not dispute the vertical movement, but had 
always admitted it. 
Mr. Morton understood Mr. Hartop to have contended at Wakefield, and 
before the British Association, that the great dislocation of the strata in the Don 
valley was the effect of a lateral movement to the Eastward, and not of a lift up 
to the North. 
Professor Johnstone said, the question appeared to be, whether besides the 
vertical movement there had been a lateral movement, and whether that would 
explain the phenomena observable. 
Mr. Hartop said it was useless to argue that there had been a throw-up, for 
instead of disputing that, he had calculated it to be a throw-up of 700 yards. 
Mr. Morton said the notion was extensively entertained that the movement 
had been lateral and not vertical; and, therefore, he had addressed himself to 
that part of the argument respecting which Mr. Thorp brought before them much 
valuable information, and whose sections proved that there is an enormous 
elevation of the strata to the Northward, and not a sliding of the strata towards 
the East. 
Professor Johnston remarked that Mr. Thorp’s explanation would account for 
all the phenomena he had observed, that Mr. Hartop had brought under their 
notice one or two other effects, which seemed to have escaped Mr. Thorp’s notice; 
and if these were correct, they would require some further explanation, on which 
the professor made a few further remarks. 
Mr. Charles Morton then proceeded to read a paper “ On the Utility of 
Geology, as applied to Mining, Agriculture, and the Arts.” We are not able to 
give more than a few lines in reference to this interesting paper. He remarked, 
that geologists had too long been considered to be mere antiquarian theorists; but 
his object was to show the high utility of Geology. He adverted to the internal 
condition of the earth, as capable of being known from its exterior surface, and
