Lammastide: How to keep hired reapers on their feet during the harvest.

'For the lethargy, or extreme drowsiness provoked by heat, you shall by all violent means, either by noise or other violent disturbances...keep the party from sleeping; and whensoever he calleth for drink, you shall give him white wine and hyssop water, of each a little quantity mixed together, and not suffer him to sleep above four hours in twenty-four, till he come to his usual wakefulness.  Which as soon as he hath received, you shall then forthwith purge his head with the juice of beets squirted up into his nostrils.'

from 'The English Housewife', Markham, 1683
