Laing's Knox, vol. ii. pp. 369-70.

The year of God 1563, there was an universal dearth in Scotland. But in the northland, where, the harvest before, the Queen had travelled, there was an extreme famine, in the which many died in that country. The dearth was great over all, but the famine was principally there. The boll of wheat gave six pounds; the boll of bere, six merks and a half; the boll of meal, four merks; the boll of oats, fifty shillings; an ox to draw in the plough, twenty merks; a wether, thirty shillings. And so all things appertaining to the sustentation of man, in triple and more exceeded their accustomed prices. And so did God, according to the threatening of his law, punish the idolatry of our wicked Queen, and our ingratitude, that suffered her to defile the land with that abomination again, that God so potently had purged, by the power of his word. For the riotous feasting, and excessive banqueting, used in Court and country, wheresoever that wicked woman repaired, provoked God to strike the staff of bread, and to give his malediction upon the fruits of the earth. But, O alas! who looked, or yet looks to this very cause of all our calamities.
