It is worthy of notice in this connection that, with scarcely 

 an exception, when squirrels are thus found on moorland, 

 they are travelling in a northerly direction ; in this matter 

 my correspondents' observations coincide in every case which 

 I have been able to inquire into. 



We have evidence also that planting to any great extent 

 did not take place around Crieff until the end of last century. 

 Torlum Hill, now said to be the highest hill in Scotland, 

 which is covered with wood to its summit, w^as, before being 

 planted, a singularly bare hill, as indeed its name signifies. 

 All the woods for some distance eastwards are of compara- 

 tively young growth, and the country was not nearly so well 

 wooded as it is now. 



The above would, in some measure, appear to indicate that 

 Crieff and Monzie parishes owe their population to the 

 southern army ; but it is almost impossible to decide whether 

 — taking 1821 as the date of their first appearance in the 

 south of Perthshire, and 1812 as that of their first appear- 

 ance at Methven {vide infra) — they would take longer to 

 press northward and eastward to Crieff from Kincardine, or 

 southward and westward from Methven. The distance be- 

 tween Frew Bridge and Crieff is eighteen miles as the crow 

 flies ; that between Methven and Crieff about twelve. We 

 know that they abounded in the woods of Kincardine in 

 1821, and so, probably, arrived there some years earlier; and 

 we also know that the first seen at Methven was in 1812, 

 and that they were rare in Crieff and Monzie even as late as 

 1841, and were only locally distributed, — as proved by the 

 late Sir Thomas Moncrieffe's notes on the specimen chased 

 by the tailor in 1832 or 1833, and the one shot by his game- 

 keeper's father in 1834, near Logiealmond. 



My idea at present is, that the southerly wave from Dun- 

 keld had not passed much beyond Methven between 1812 

 and 1845 in the directions of Crieff and Monzie, but had rolled 

 on in greatest force in a more south-easterly direction ; and 

 that these Crieff and Monzie records apply really to a 

 northern offshoot of the southern army, indicating, perhaps, 

 the furthest north point the Dalkeith and Minto army had 

 reached before mingling with the Dunkeld southern division.
