THE Map is constructed and coloured to show the situation and possessions of the Clans, and the properties of the landlords, in the Highlands and Islands of Scotland. The Clans are enumerated in two Acts of the Scots Parliament, passed in 1587 and 1594 respectively. The names of the landlords are appended to the Act of 1587. There is thus historical authority for the names and possessions of the persons occupying all the north of Scotland at the end of the sixteenth century. This early date was selected, because then most of the Highland tribes were still in occupation of the lands which they had inherited from their forefathers. During the troubles of the following century some of the weaker clans were deprived of their possessions by their stronger neighbours. (1) In compiling the Map Mr Johnston and Colonel Robertson made every effort to secure accuracy. It will be understood, however, that in most cases the boundaries of clan territories can be only approximately indicated. The rotation and numbering of the Clans and Landlords have been made as they occur in the Acts of Parliament. On the Map the residences of the chiefs and heads of families are marked in black, having the number of the clan below in upright print, while the possessions of the landlords are named in italics with Roman numerals.
