DR JOHNSTON'S ADDRESS. 46 



and the gradual growth of the latter. Etchings from these speci- 

 mens were promised by our zealous member to adorn the present No. of 

 the Club's Proceedings. Mr Selby next laid before th^ meeting a 

 table of the first appearance of our Migratory Birds at Twizel for about 

 twenty years, accompanied with remarks ; and this valuable table will 

 form a prominent article in our Proceedings. 



The station of our meeting in June afforded a strong contrast with 

 that of May. Horckloy stands on the verge of a steep precipice, and 

 overhangs the Tweed where the noble river has reached its full breadth 

 and depth, and where it winds

 a subsidiary burn, while it opens westwards and to the north in a wide 

 common and barren muir, which no poetry can elevate into beauty. 

 It was across this common and muir that our morning walk lay, travel-

 borealis, the ever-green memorial of our groat master. In our pro- 

 gress a few plants were picked that are worthy of notice. The pretty 

 Sedum villosum drew occasional attention ; a Pyrola was examined, and 

 was considered to be the P, mediae but the unexpanded state of the 

 blossoms forbad more than a conjecture ; the Potamogeton oblongwn 

 occurred in almost every shallow ditch, flowering freely; and in a ditch near 

 the Eden, which was crossed in our walk, there grew in profusion Potamo^
