According to J. Colquhoun, Esq., they were first seen in the 

 western and major part of the county in 1830.* In 1863, 

 in consequence of damage done to larch trees, orders were 

 given to destroy them on Sir James Colquhoun's estates — 

 Rossdhu parish — and many hundreds were killed.f In 1864 

 they were still abundant there, and in 1877, Mr James 

 Lumsden reports that " they were still extending their distri- 

 bution." J 



We thus find that another flank movement is made 

 into Dumbarton, and we find them recorded from locali- 

 ties on either side of Loch Lomond, almost opposite one 

 another ; in Luss and Buchanan about the same time — viz., 

 1830. 



From Stirlingshire we now follow the more widely spread- 

 ing army ; First, eastwards and north-eastwards, populating 

 Clackmannan, and Fife, and Kinross, and rounding the north- 

 east end of the Ochils, or penetrating across them by the 

 various valleys. 



We will then, so far as practicable, trace their advance 

 through the southern parts of Perthshire until they meet the 

 army from another centre at Dunkeld (vide under Dunkeld 

 Centre, p. 142). 



We will find them also pushing their way through the 

 mountain passes of the Trossachs and Aberfoyle, reaching the 

 head of Loch Lomond and here joining forces with the Dum- 

 bartonshire wing, and with the westerly extension of the 

 Dunkeld army, — yet to be spoken of, — meeting also an ex- 

 tension in all probability from an introduction at Minard, in 

 Argyleshire (q.v.).

In Clackmannan a squirrel was killed on the coronation 

 day of her Majesty — June 20, 1837 — by one of a p^rty of 

 some twenty bark-peelers, in the Dollar district ; and James
