that a circumcision of the bark has the same effect in inducing 

 lateral buds as the actual amputation of the branch has. In 

 either case the aim is to repair an injury, and hence the 

 vigorous development of buds in the region where the injury 

 is felt. 



These experiments give merely a glance into what might be 

 made as wide a subject as you please, and they claim no more 

 than what they show in the individuals dealt with.

The specimen of Juncus tenuis I have to show was found on 

 the roadside near Lochgilphead on the 29th September, 1902. 

 The road runs parallel with the Crinan Canal for some distance 

 on the Argyllshire side of the canal, and is probably the most 

 frequented in the district, being the coach road to Ford, which 

 links Lochgilphead and Ardrishaig with the railway, as well 

 as being the road to Crinan, which links Loch Fyne with the 

 Atlantic. 



The plant was growing in considerable quantity, associated 

 with such forms as Juncus hufonius, J. lamprocarpus, &c., and, 

 whatever its previous history may have been and its future fate 

 may prove, it was, to all appearance at least, flourishing there 

 with the freedom and confidence of an established denizen of 

 the district.
