Fio. 15,— Loch Trool. View t'lora the Earl of Galloway's boat-house, looking 

 across the loch. The narrow channel formed by the two wooded promontories 

 (see also figs. 13 and 14) is indicated at the left centre of picture. The 

 narrow zone of rocky shore is very bare of littoral plants. 



Fig. 16.— Loch Grennoch (by Gairnsuiore of Fleet). View from the north-west 

 end, looking south. The sandy bays are not well shown as the scale is so 

 small. This wind-exposed loch has scarcely any littoral vegetation.
