their fordid way of life, will extort from him many ufeful reflec- 
tions. He fliould alfo take with him an able draughtfman ; for 
he muft by no means pafs over the noble caftles and feats, the 
extenfive and pidurefque lakes and waterfalls, and the lofty 
ftupendous mountains, fo little known, and fo engaging to the 
imagination when defcribed and exhibited in a lively manner : 
fuch a work would be well received. 
As 1 have fcen no modern map of Scotland, I cannot pretend to 
fay how accurate or particular any fuch may be ; but this I know, 
that the beft old maps of that kingdom are very defedive. 
The great obvious defed that I have remarked in all maps of 
Scotland that have fallen in my way is, a want of a coloured line, or 
Jlroke, that fliall exactly define the juft limits of that diftrid called 
The Highlands. Moreover, all the great avenues to that moun- 
tainous and romantic country want to be welt diftinguifhed. The 
military roads formed by general IVade are fo great and Roman -like 
an undertaking that they well merit attention. My old map,^ 
MolVs Map, takes notice of Fort JVilUam ; but could not mention 
the other forts that have been erected long fince : therefore a good, 
reprefentation of the chain of forts fhould not be omitted. 
The celebi\ited zigzag up the Coryarich muft not be palTed over. 
Moll takes notice of Hamilton and Drumlanrig, and fuch capital 
houfes ; but a new furvey, no doubt, Ihould reprefent every feat 
and caftle remarkable for any great event, or celebrated' for it's 
paintings, &c. Lord Breadalbane's feat and beautiful policy are too 
curious and extraordinary to be omitted. 
The feat of the Earl of EgUntoun, near Gtafgow, is worthy of 
notice. The pine-plantations of that nobleman are very grand 
and extenfive indeed.. I am, &c.
