pistillate at the apex. This is very unusual, the species being 

 generally distinctly dioecious. 



Mr. John Paterson reported that the fine Black Poplar which 

 stood at the side of the Luss Water, near the bridge, has been 

 cut down. It measured 13 feet in circumference, at 5 feet, 

 thirteen years ago (vide Annals, Andersonian Naturalists' 

 Society, L, p. 60). It is stated to have been planted in 1804, 

 but only fifty-four annual rings of growth could be counted at 

 the base of the trunk. The apparent annual increase of wood 

 was uniformly large throughout that period. There is much 

 natural Holly in Luss Glen, some of it pretty old, and individual 

 trees of large size are quite a feature of the place. The Tulip 

 tree and curiously-shaped Larch, in the Hotel garden, the old 

 Wych Elm, opposite the Hotel, the large Silver Firs, Great 

 Maples, Limes, and Walnuts all received their due meed of 

 attention and admiration, but no fresh measurements were 

 taken. 



Dungoynb, 7th June, 1902. — This excursion was undertaken 

 jointly with the Geological Society, and was under the leader- 

 ship of Mr. James Steel. Notwithstanding a wet forenoon, 

 which did not promise well for an afternoon on the moors, 

 nineteen members and friends assembled at Queen Street Station, 

 and on reaching Dungoyne Station the number was swelled by 

 the addition of several others. The fact that there had been 

 so recently the terrible eruptions in the West India Islands 

 induced the members to pay special attention to the signs of 

 former volcanic energy around them. On the way to the 

 summit of the hill several vents were noticed, from which the 

 andesite lavas which cap the Strathblane hills were poured 

 forth, which in turn at a later period were traversed by in- 

 trusive diabase. Dungoyne itself is the most conspicuous of 

 the vents, but among others in the vicinity are Dungoil, Bin 

 Bairn, and the Meikle Bin. According to Sir Archibald Geikie, 

 there are fifty vents, large and small, between Dungoyne and 

 Loch Lomond. There was a beautiful and extensive view from 

 the top of the hill, and many quick-passing shadows varied with 

 sunshine gave diversity to the scenery, making the visit a truly 

 memorable one. Returning round the south face of the hill at
