No water was met with in the Keuper marls in this boi'ing, nor were 

 any brine or rock-salt beds reached. In a boring a few miles to the 

 east, at Preesal, on the east side of the River Wyre, a boring carried into 

 these marls had intercepted a bed of rock-salt more than 100 feet in 

 thickness, on the surface of which brine rested. The surface of th.e 

 ground is about 40 feet above the Ordnance datum-line. 



In last year's Report details of a boring at Mr. Hull's brewery at 

 Preston were given, the depth being 246 feet ; the rock, pebble-beds, of 

 the New Red Sandstone, the water rising to 65 feet above the Ordnance 

 datum. 



Two miles to the north the following well and boring have since been 

 made by Mr. Yivian of the North of England Rock Boring Co., for Mr. 

 Sumner, near Fulwood Lodge, Watling Street Road. Collected by Mr. 

 C. E. De Ranee from Messrs. Myers and Veevers, C.E., Preston. Surface 

 of bore-hole 160 feet above Ordnance datum.
