EXCURSIONS TO LOCH LOMONDSIDE. 63 



(31st August, 1889) Ben Voirlich was ascended. The flora of this 

 hill was familiar to local botanists before our visit, nor was 

 anything noted which had not been known as occurring there. 

 On the second excursion, however (18th July, 1891), new ground 

 was broken, Ben Ime (3318 feet), which lies north of the familiar 

 Cobbler, being ascended. Following the course of the Allt 

 Bhallachan, a typical mountain torrent, the watershed to the north 

 of the Cobbler (2250 feet) was followed, thence up the long 

 grassy slope to the cairn at the summit of Ben Ime. The 

 descent was made down the course of the Allt Coiregrogan into 

 Glen Loin, which opens into the head of Loch Long. This part 

 of the route yielded by far the best results, most of the plants in 

 the list which follows having been gathered there: — Ranunculus 

 Flammula, Thalictrum alpinum, Viola lutea, Cerastium viscosum, 

 Silene acaulis, Polygala vulgaris, Geranium sylvaticum, Potentilla 

 Torme?itilla, Alchemilla vulgaris, A. alpina, Rubus saxatilis,

In the village of Arrochar a magnificent ash tree attracted 

 attention. The trunk measured 16 feet 5^ inches in girth at 

 5 feet 9 inches. 



At the Ben Voirlich excursion a handsome oak, half-way between 

 Ardlui and Voirlich Burn, on the east side of the road, was 

 measured (girth, 12 feet 6 J inches at 4 feet).
