406 PRESIDENTIAL ADDRESS. 



met at the station by Mr. Inglis, his lordship's head gardener, 

 who acted as our cicerone during the day, and showed us all the 

 beauties of the noble mansion and the lovely park. 



The following paper, contributed by Professor Lebour, was 

 read at the fourth Field Meeting : — 



In the past year the chief geological points wbich require 

 notice are the Seaton Carew Boring, the Dunston Excavations, 

 and the Publications of the Geological Survey. 



Beginning with the last, attention must be drawn to Mr. 

 Clough's Memoirs on the Cheviot country and on the country 

 around the Plashetts district of the North Tyne. These memoirs 

 contain a very large amount of new information, perhaps the 

 most important and newest of which is the unexpectedly large 

 area occupied by Granite in the Cheviots. Both are the con- 

 densed resume of a very detailed series of observations, and 

 cannot be usefully abstracted. They must be carefully studied 

 themselves. The same may be said of a very elaborate Memoir 

 on the Lower Carboniferous Rocks of the Rede Water, by Mr. 

 Hugh Miller, published before the past year, but which has 

 scarcely attracted the attention which it deserves. The lists of 

 fossils from various horizons in the Limestone Series are unique 

 and of the greatest value. 



The Seaton Carew Boring has been put down by subscription 

 between the village and the railway, and the interest of its re- 

 sults can scarcely be over-estimated. After proving the Salt- 

 measures (Triassic or Permian according to different authorities) 

 without, however, finding any salt, and after giving the first 

 known complete section of the Magnesian Limestone, and prov- 

 ing that rock to be some 800 feet thick, a series of grits, sand- 

 stones, and shales, with thin coals, was struck, which may in 

 part belong to the Millstone Grit Series, but in all probability 

 comprise a very large amount of Coal-measure rocks (probably 

 Lower Coal-measures or Gannister beds). However this may 

 be (and a boring about to be put down at Hart will soon prove 

 this), we have here an undreamed of extension of the Coal- 

 measures, which may mean another Coal-field between those of 

 Yorkshire and Durham. Borings at Middlesbro', or a little
