EXPLANATION OF PLATES. 

 Plate I. 



Fig. 1. Section through the older stratified peat deposits in the Dale of Burn, W. Shetland. 

 Fig. 2. Showing the older stratified peat deposits on the Weisdale Hills, Shetland. The measurements 

 and position of the trees in the forest bed at this spot are given in PI. V. fig. 36. 



Plate II. 



Fig. 3. Section opposite Lunga Water, W. Shetland, showing the junction of the newer unstratifipd peat 

 and the weathered boulder clay. The base of the peat is shown at the top, and the weathered boulder clay 

 containing birch bark in the middle of the photograph. The unaltered boulder clay is shown at the base 

 of the figure. 



Fig. 4. Showing the denudation of the peat at 600 feet on Stanevatsoe Hill, W. Shetland. 



Plate III. 



Fig. 5. Section through newer unstratified peat deposits on Mousa Vord, W. Shetland, showing 

 indefinite banding of Sphagnum. 



Fig. 6. Pinus sylvestris in the second tier of forest at Slochd, Inverness-shire, described on p. 818.

 Fig. 8. Viola palustris. x 12. Lower Forest, Shetland. 



Fig. 9. Lychnis diurnal x 15. Lower Forest, Shetland. This agrees very closely, but the spines are 

 longer and more slender than in modern seeds.
