188 THE NATURAL HISTORY [LETT. 



As I have seen no modern map of Scotland, I cannot pretend 

 to say how accurate or particular any such may be ; but this I 

 know, that the best old maps of that kingdom are very defective. 

 The great obvious defect that I have remarked in all maps of 

 Scotland that have fallen in my way is a want of a coloured 

 line or stroke that shall exactly define the just limits of that 

 district called the Highlands. Moreover, all the great avenues 

 to that mountainous and romantic country want to be well dis- 

 tinguished. The military roads formed by General Wade are 

 so great and Roman-like an undertaking that they will merit 

 attention. My old map, Moll's map, takes notice of Fort 

 William ; but could not mention the other forts that have been 

 erected long since : therefore a good representation of the chain 

 of forts should not be omitted. 



The celebrated zigzag up the Coryarich must not be passed 

 over. Moll takes notice of Hamilton and Drumlanrig, and such 

 capital houses ; but a new survey, no doubt, should represent 

 every seat and castle remarkable for any great event, or cele- 

 brated for its paintings, &c. Lord Breadalbane's seat and beau- 

 tiful policy are too curious and extraordinary to be omitted. 



The seat of the Earl of Eglintoun, near Glasgow, is worthy of 

 notice. The pine-plantations of that nobleman are very grand 

 and extensive indeed.
