And others. 



The following trees have been discovered: — Hawthorn, elder, common ash, 

 birch, alder, hazel, oak, willow, yew, and fir, all of which, with the exception of 

 the ash, are considered natives of Scotland. The cones of the silver fir have been 

 dug out of the peat in Orkney, but this tree is not now indigenous to Scotland. 

 Several shrubs, including the juniper and raspberry, as well as many flowering 

 plants, have also been discovered. 



On a map prepared by the author the localities are marked where the various 

 trees have been found. The records are probably not complete, but are sullicient 

 to show the distribution. 



It will be seen that there are few parts of Scotland, however treeless at the 

 present day, that were not in remote, and even iu comparatively recent times 

 covered with woodlands. This is also shown ^}J the place-names. As regards 

 the special trees : — 



The oak is very widely distributed. Its most northern occurrence is Caithness- 

 shire, and it is recorded in every other county. It has even been found iu the 

 peat bogs in the now treeless islands of Lewis and Tiree. 



It is interesting to note that many of the oaks have been found at high altitudes, 

 c.ff., 800 feet above sea-level (parish of Croy, Inverness-shire), and of considerable 

 size, e.</., 70 feet in length (Drumcrief). 



The Scots fir, probably the rinns sijlvesfris, is another widely distributed tree. 

 It is common in the Northern Counties, in the Orkneys and Lewis, in all the 

 Midland Counties, with the exception of Forfar and Fife, but in the Southern 

 Counties it is only recorded in Renfrew, Edinburgh, Roxburgh, Dumfries, and 

 Wigtown. 



The hazel has been found in the submerged forests, and in many other parts of 

 the mainland, as well as in the Orkney and Shetland Islands and in many of the 

 Western Isles. No record has been found of its occurrence in Sutherland, but 

 throu<^hout the Midlands it is fairly plentiful, and in the Lowlands it has been 

 noted in all the counties, with the exception of Haddington, Linlithgow, Selkirk, 

 Dumfries, and Wigtown. 



The birch is recorded in the Orkney and Shetland Islands, and in the majority 

 of the counties from Caithness to Wigtown. 



Reo-ardinc the other trees few records have been discovered. The alder is 

 recorded from Lewis, Banff, Aberdeen, Kincardine, Perth, Fife, Argyll, Lanark, 

 and Edinburgh. Willows (species unknown) are noted in both Caithness and 

 Sutherland. They have also been obtained from the peat bogs in Renfrew, Lanark, 

 and Roxburgh. The ash is generally regarded as a probable native in the soutli 

 of Scotland.
