Anniversary Address. 187 



Mr. D. Milne Home went across the country, in carriages 

 provided by him, to the circle of standing stones near Grindon 

 Eidge, and to the ruins of Duddoe Tower. The other party 

 — ^led by Mr. G. Tate — strolled up the river to explore the 

 botany and geology of the valley ; Asplenium Ruta-muraria 

 was found growing sparingly amongst the rocks. The 

 rocks examined belong to the Tuedian group, the lowermost 

 division of the carboniferous formation ; teeth and scales of 

 Rhizodus Hilherti and of other ganoid fish were discovered, 

 and the remains of Lepidodendron and other plants. A 

 large slab was seen opposite to Milne Graden, telling the 

 story of an ancient estuary beach j long, deep, wavy ripple 

 marks were there, and the tracks of numbers of organisms, 

 which had crawled over that beach ; and besides, there were 

 the borings of other creatures passing perpendicularly through 

 the strata. A little above Milne Graden — at Tweed Mill — 

 are remains of Araucarian trees associated with species of 

 Orthoceras, Pleurotomaria, and other marine moUusks. 



The two parties reunited, by appointment, about 3 o'clock 

 at Twizel Castle. This castle belongs to the Blake family, 

 and stands upon the margin of the river Till, near its junction 

 with the Tweed ; it commands a most extensive and beautiful 

 view ; the Cheviot range to the south, the Eildon Hills to 

 the west, Berwick Law to the north, and the sea to the east. 



At Milne Graden, a remarkable and magnificent specimen 

 of a fossil tree, above 20 feet in length, found in an adjacent 

 quarry, was shewn by Mr. D. Milne Home, who afterwards 

 conducted us to dinner. 



After dinner, Mr. Robert Embleton, read a paper " On the 

 Nidification of the Fifteen Spined Stickleback," and exhi- 

 bited two of its nests; and the Rev. Robert Greenwell, 

 " Notes of the Opening of Ancient British Tumuli in North 

 Northumberland in 1863." The Rev. W. C. King was 

 requested to undertake the exploring of the stone circle near 

 Grindon Ridge. 



The Members proposed at the last Meeting were elected ; 

 and the following nominations were made, viz. : — the Rev.
