There are also numerous local Guide-books to certain parts of 
Caithness, written to induce the British tourist to visit the principal 
lions of the county, many of which contain much interesting local 
matter. Amongst those known to us we may mention the follow- 
ing :— 
A Handbook to Thurso and Vicinity, and Guide to the County of Caith- 
ness. Thurso. Miss Eussell. n.d.

Descriptive passages occur in Hugh Miller's Testimony of the 
Bocks, and his Footprints of the Creator (in which Mr. Eobert Dick 
is conspicuous for his share of the material supplied), and in 
the writings of Sir Eoderick Murchison. In Hugh Miller's Old 
Bed Sandstone (p. 57) occurs a descriptive passage, and the geology 
is epitomised. Professor Geikie has also many references — 
descriptive or geological — to the county, which are deserving of 
attention.
