Note 3 — Chapter I · INTRODUCTORY.
Reading edition
Coll is also a very interesting island for the antiquarian. It contains distinct traces of twenty-nine Hill-forts or Duns, so that there must have been lively times out there long ago. Some fine shells, beads, pins and pottery have been found in the prehistoric kitchen-middens. Before the Reformation the island was thickly peopled, and sites of old churches and deserted crofts are numerous. Coll has gone back in population; in 1901 it had 432 inhabitants; in 1755 the number of natives was 1,193.
