great exactness, enabling me to trace their further eastward 

 progress. Around Huntly, at Dunblade, they appeared 

 " about fifteen years ago " — say 1864; and on the estate of 

 Haddo, parish of Forgue, south side of tlie river Doveran, and 

 in parish of Inverkeithnie, about the same time. Then at 

 Lathers, parish of Turriff, and Netherdale, parish of Marwick, 

 "about thirteen or fourteen years ago" — say 1865-66. In 

 about the year 1867 (" about twelve years ago") they appeared 

 at Fyvie and Delgaty, in the parishes of Turriff and Fyvie 

 (Aberdeenshire), which "are the most easterly localities 

 where they at present (1879) occur." * In about the same 

 year, they also appeared in Auchterless parish, at Ardmiddle, 

 and on the estates of Forglen and Carnoustie (Banffshire). 

 Here the Kev. W. Gregor gives me the further note, that 

 " some sixteen years ago they were not seen at Duff House, 

 near Banff, but are now said to be there." And, subsequently, 

 he adds, that he has found the squirrel in Deer parish. 



We will now cry back again, and in order to trace their 

 advance to districts south-west of Beaufort on both sides of 

 Loch Ness, I give the record supplied to me by Mr Morrison, 

 factor on the Dochfour estates, that " about the year 1848, it 

 was first seen on Loch Ness side [north side] in the hazel 

 plantations belonging to Lord Seafield, about four miles west 

 of Dochfour, and it was supposed to have crossed the hill 

 from the plantations near Beaufort. It, of course, speedily 

 increased in numbers, and in course of twelve months later 

 it was first met with on the south side of Loch Ness, in the 

 plantations of the late Sheriff Tytler of Aldourie, and in 1850 

 it had spread over the Ness Castle plantations east of Aldourie ; 

 and by this time it was discovered that its introduction into 

 the north was likely to prove seriously injurious to planta- 

 tions generally." 



The above, I think, goes to prove its eastward advance 



* Since the above was written, I have learned that two squirrels were 

 killed upon the Aberdour portion of the Brucklay estates, in a deep wooded 

 glen called the Den of Glasslaw, three or four years ago — say 1875 or 1876. 

 They have not as yet been seen at Brucklay. The Aberdour part is close to the 

 sea, and about twelve miles from Brucklay Castle, and adjoins the estate of 

 Troup, where there are also a few reported to have appeared. I am indebted 

 to my friend, Mr W. Horn, for this additional note.
