Reading edition
Two Centuries of Irish History, edited by Bryce, p. 21. Sir Horace Plunkett estimates that Ireland can now support about 2,500,000 agriculturalists or 500,000 families (Ireland in the New Century, p. 30). The population in 1790 was estimated at over 4,000,000. In the sixteenth century it was probably less than 1,000,000.
