Plenty of clean water must be conveniently at hand for the cows to
drink. The water must be sweet and clean enough for the human stomach.
Abundance of such water is more essential in the pasture--for the cows
to drink while secreting milk that contains 87 per cent. of water--than
it is in the daily-house, where a small amount of water will answer, if
ice is used, and hence can more easily be obtained pure.
