Works for the manufacture of salt formerly existed at Tod Point ; bat, 

 Mr. Peacock states, whether sea water or the brine spring from the sea 

 was used, is doubtful. About 1856, a 6-feet shaft was sunk on the marsh 

 near Coatham, by the late Mr. Slate, of Redcar, in a fruitless seai'ch for 

 coal ; a strong brine was met with, to find which, the above boring was 

 put down, but the brine spring met with did not realise expectation. 



This boring is valuable as showing the actual junction of the lias and 

 marls with gypsum, which latter, as pointed out by Mr. Peacock, are 28 

 yards thick in the Middlesboro' boring. The limestones, thick salt-beds, 

 and gypsum in that boring, are probably referable to the Permian ; the 

 intervening beds of red sandstone, 673 feet, are probably referable to the 

 Water Stones and Lower Mottled Banter, the Upper ^lottled and Pebble 

 Beds having thinned out. 



It would appear that a gradual overlap eastwards takes place in all 

 the Triassic strata, along a north-east and south-west line, the more marked 

 transgression being that at the base of the Keuper Water- stones, and at 

 the base of the Pebble Beds of the Bunter, lines of extensive erosion 

 occurring at the base of the Keuper building stones and conglomerates, 

 and on the base of the Pebble Beds of the Bunter. The great thickness 

 of these Triassic deposits in the north-west, is proved by these borings, 

 and their thinning out to the south-east is established, and has an im- 

 portant bearing on the depth to concealed coalfields as well as on the 

 water-bearing capacity of the Triassic sandstones.
