SUTHERLAND, CAITHNESS, AND WEST CROMARTY. 19 
areas, to be described with an intelligent appreciation of their 
part in the great plan of creation. Nor does the work of the 
geographer or the naturalist cease here, for we have still the 
coast-lines, and we have still the wonders which lie beneath 
and around in every branch of science. Topography and place- 
names claim no inconsiderable share of attention ; yet if we look 
around, how few works have ever treated of this mine of wealth. 
Let no one say our knowledge of our own. country is nearly 
yet complete.
