everywhere in large numbers both here and beyond the Firths 

 in Stirlingshire * (q.v.). 



In North Lanarkshire, we find that, " though formerly a 

 stranger in these parts, it has become of late common through- 

 out all the wooded districts of Clydesdale, f It had reached 

 into Cadder, J Cambuslang,§ and Cambusnethan,|| where it 

 had established itself throughout the whole of the district." 



Of its occurrence in Lanarkshire, we find no mention in the 

 wonderfully exact work of David Ure — "The History of 

 Eutherglen and East Kilbride," published in 1793. 



Before tracing their advance further northwards, we must 

 cry back and pick up a dropped loop in our chain of evi- 

 dence, and recount the interesting particulars of the Minto 

 restoration in Eoxburghshire, which, as I will show, must 

 be considered as the centre for another tract of country. 

 Thereafter, an examination of the Map (Plate IV.) will assist 

 in making the areas populated from each centre more easily 

 understood.

Eegarding the former occurrence of the squirrel on the 

 Borders, see remarks on " Historical Evidence in Scotland " 

 (Part IL, antea, p. 37). 



Squirrels were unknown in the county when the present 

 century began, and it was a rare sight fifty years ago, — say 

 1830.1F Tate** states that it was "not resident so much as 

 half a century in Wolflee woods, near Hawick." Tate, 

 writing in 1868, would place this date within 1830. There 

 were '' none in 1820, when Sir Walter Elliott left his home : 



only seen one or at most two in that time. Captain Leckie is quite sure 

 there has been no organised destruction of them on the adjoining properties 

 nor there, and he suggests the possibility that the smoke from neighbouring 

 paraffin works may have driven them away. This is quite possible, I believe, 

 if the trees are affected by the smoke (Letter from Captain N. H, Leckie, 

 The Thorns, Uphall, Linlithgow).
