Federated Institution of Mining Engineers VOL. II, PLATE II To illustrate McGeorge Lewis's paper on "A Geological Sketch of the Town & District of Nottingham Transactions 1890-91. VOL. II, PLATE III To illustrate McGeorge Lewis's paper on "A Geological Sketch of the Town & District of Nottingham. The question of the causes which have led to its formation is far too complicated to be thoroughly treated in a short paper of this description; but it certainly appears an interesting subject. In the writer's opinion, various causes have led to the formation of these deposits; but those immediately in question have, he believes, been deposited in inland lakes, the waters of which have been evaporated. Whatever the cause may have been, they find a useful place in the manufactures of this country, and point to another instance of a wise provision that nature has formed and stored up in the crust of the earth for the uses of man. The CHAIRMAN-I am sure Mr. Lewis will be willing to respond to any question any member would like to ask him, although the paper is more of a descriptive than of a controversial character. Mr. W. BEATTIE-SCOTT (H.M. Inspector of Mines, Birmingham) asked Mr. Lewis if it was to be understood that the water-bearing strata he spoke of in Nottingham extend only to the Magnesian Limestone, or that they descend into the lower geological horizon? If the former, do they take the form so well known in the north as "quicksand formation?" Mr. G. LEWIS-We find on sinking, in the upper strata and the limestone also, large quantities of water, but very little water after reaching the Coal-measures. So far as I am aware, quicksand has not been found at any sinkings in this district. We always find sand, but it is pretty strong and being very porous holds a large quantity of water. It is full of crevices. No one else asking any questions, the CHAIRMAN said he was sure they were very much obliged to Mr. Lewis for his paper. Those who were going with the excursions on the morrow would now be able to enjoy themselves much better than they otherwise would have done if the route had not been explained. Mr. G. LEWIS expressed his acknowledgments. Mr. M. H. MILLS read his paper. A few Notes on the Ironstone Deposits of Leicestershire," as follows: |
