18 Anniversary Address 



And likewise the lard of Farnehurst and his tenants uppon the 

 other side north and west neare unto the same. And £oe w^li 

 their Oattell in Common they doe pasture and eate the said 

 ground in traverse in the sommer tyme but neither parte builded 

 thereuppon." In this outlandish place, duels appear also to have 

 been fought, in lawless times. Eobert Snowdon, born at Hepple, 

 in Eothbury parish, we are told, " in the 16th year of his age, 

 fought and slew John Grieve, a celebrated Scotch champion, in 

 a pitched battle, with small swords, upon Gamble path, on the 

 borders." This is said to have happened before the Union. 

 (Mackenzie, vol. ii., p. 76, Note). 



It was most interesting to alight upon Greywacke at Chew- 

 green, and to have its accompanying slates laid bare in the deep 

 foot drains ; the grey clay resulting from their decay forming the 

 subsoil. This had not been overlooked by one to whom the Club 

 owes much, the late Mr George Tate. In his memoir prefixed to 

 the " New Flora of Northumberland and Durham" pp. 3-4, he 

 says, " Cambro- Silurian strata are highly inclined against the 

 porphyry, in the bed of the Coquet a little above Philip, and ex- 

 tend beyond the source of that river into Scotland. In a deep 

 ravine, eastward of Makendon, they are well exposed ; and the 

 Eoman camp at Chew Green is formed out of tham ; for some of 

 the rampiers are natural walls of Greywacke m situ, the rock 

 having been removed on both sides. Southward of the Coquet 

 they extend for some distance along Watling Street." In his 

 "Outhnes of the Geology of Northumberland," p. 46, Professor 

 Lebour also refers to this junction on the Coquet, : "between 

 Philip and Makendon, the porphyrites which form the main mass 

 of the Cheviot range are seen in a beautifully clear section abut- 

 ting against grits of the Silurian age or Greywacke. The latter 

 are bent up on end by the intrusion of the former, thus giving a 

 limit of age to that event." On this point as bearing on the age 

 of the Cheviots, Professor Lebour thus recently writes me : "I 

 used to regard the whole mass of Cheviot rocks much in the same 

 way as George Tate did, i.e., as being a huge boss which had 

 been pushed through the old Silurian, and possibly other pre- 

 Carbonif erous rocks bodily. The recent researches of the Scotch 

 survey, however, as well as those of Messrs Gunn and Clough of 

 the English survey, incline me to think that I was wrong, and that 

 although undoubtedly, somewhere or other, the porphyrites, etc., 

 do pierce through the Silurian rocks of Makendon, etc., yet the
