(VIII-36 and onwards) while recommending the four-fold sites for the laying out of forts shows a clear cognizance of this fact with the provision of these natural defences—the mountain (top level), the forest (a belt of dense trees round water reservior), the river-islands, and the artificial make up with the parapets and and ramparts, etc. Here the first three serve as natural forts, the last is the constituent of the artificial one.
