Lycksele Lappmark, 05/06/1732, ¶380:

When times get hard around here, the farmers eat chaff and even pine bark, which they peel off, remove the scales, grind and bake. They also keep it for their cattle, cutting it obliquely in pieces the size of 2 fingers and giving it to the cattle, goats and sheep. This economises considerably on fodder. The bark is peeled off when the sap is rising and then dried in the sun and kept for the winter. They grind it and bake bread from the flour. They also use it to make swill for fattening pigs and the animals fatten up well on it, thus making a saving on grain.
