in 1550, the same kind of a laborer earned 4 pence in a day. He paid 1
shilling 10-1/2 pence for a bushel of wheat and £1 16 shillings 7 pence
for an ox. This means that he paid nearly six days' (about 80 hours')
labor for his bushel of wheat, and 110 days' (1540 hours') labor for his
ox. The high price of the latter was justified by its great improvement
in weight and quality.
