wing by the loch side. A small Cockchaffer ( Rhizotragus 

 solstitialis) was captured. Many of this beetle were seen in 

 flight. The Cinnabar Moth (Etichelia J^acobcBcs) was taken ; 

 and the Humming-bird Hawk Moth was noticed in the 

 neighbourhood of the Castle visiting the wallflowers which 

 grow plentifully and naturally on the old ruins. 



The excursion having been brought to a close, the members 

 reassembled in the village to recross the sands to the main- 

 land. The sands are covered by the sea twice a day as the 

 tide flowed and ebbed eleven hundred years ago in the time 

 of Bede. Scott's lines in "Marmion" express the natural 

 relationship of the Island to the mainland in those distant 

 ages as follows : — 



"For with the flow and ebb, its style 



Varies from continent to isle ; 



Dry-shod over sands, twice every day, 



The pilgrim to the shrine finds way ; 



Twice every day the waves efface 



Of staves and sandall'd feet the trace." 



The success of the meeting was in a great measure due to 

 the kindness and untiring energy of Mr. Bolam, of Berwick, 

 who met the first detachment of members at Beal, and who 

 throughout the day ungrudgingly and pleasantly imparted 

 his experience and knowledge of the natural history of the 

 Island.
