 Draparnaldia plumosa, Vauch., D. glomerata, Ag., and Tetraspoi\i, 

 gelntinosa, Desv., which were also plentiful. 



Fungi were investigated by Mr. R. B. Johnstone, who obtained 

 a few of the larger forms, including Coprinus plicatilis, Fr., 

 Polyporits squamosus, Fr., Mitrula phalloides (Bull.) C'hev., kc. 



Braidwood to Tillietudlem, Gth June, 1908. — Mr. John 

 Robertson, conductor. In brilliant weather .six members pro- 

 ceeded bv rail to Braidwood Station. The route taken was down 

 alongside Fiddler Gill, and through the orchards to Crossford, 

 where a halt was made for tea. The road by the Ncthan was 

 afterwards followed to Craignethan Castle and Tillietudlem 

 railway station. 



As time only permitted a pleasant ramble, little of note was 

 observed. Only four birds' nests — two Blackbirds and two White- 

 throats — were seen. The Mistle Thrush was heard in full song. 

 This was a point of some interest, as the conductor had never 

 before heard the spring notes of that bird so late as the Gth 

 of June. 



Among Flowering-plants, mention may be made of Paris 

 quadrifoUa, L., and Keottia Nidus-avis, Rich., both seen in 

 Fiddler Gill; and of Ranuncidus bulhosvs, L., Oieiranthiis Cheiri, 

 L., and Arum macuJatum, L., observed at Craignethan Castle.
