of Edinburgh, Session 1879-80. 383 
days, the area being 330 square miles of very difficult mountain 
country. 
The representation of the hill features was of necessity less exact 
than might be possible on the one-inch scale, but so far as the ridges 
and prominent features are concerned it is supposed to be accurate. 
The general slopes of the mountain sides were determined with a 
pocket level, and separate sheets of hill shading were prepared and 
carefully inked in before leaving the camp for a new district. 
The preceding notes will, it is hoped, give some idea of the 
character of the survey work. The rapid rate of progress had many 
advantages, amongst which was the economical character of the work, 
the map costing in the field not more than one penny per acre of 
ground, surveyed. 
In addition to the map work many other kinds of information 
were supplied. The ruins were explored, plans of all interesting 
places, special surveys of towns and ruined cities, and notes on the 
archaeology of the land, were regularly collected. The geological 
structure of the country was observed, collections of fossils and of 
lithological specimens were made, birds were shot and stuffed, notes 
on the traditions, manners, and language of the peasantry were 
recorded. Photographs of interesting places were also made, and a 
regular series of meteorological observations was kept for three 
years. 
It was also necessary to study carefully the literature of the sub- 
ject, in order that intelligent explorations might be attempted, and 
special observations taken in connection with the numerous contro- 
verted sites of importance throughout the country. The winter 
seasons were employed in reducing to order the field observations, 
and in preparing, by study of the literature, for the examination of 
questions connected with the topography of the district next to be 
surveyed. 
The results of these explorations are not as yet fully published. 
The lithographed sheets now on the table have been prepared at the 
Ordnance Survey Office, Southampton, from MSS. worked out in 
England after the return of the survey party. An engraved map to 
a smaller scale (-| inch per mile) is also in course of preparation, 
and the proofs seem to promise that the finished work will be of 
excellent execution.
