Plutarch's Natural Questions by Plutarch

Whether is it because the wild beasts leave off going far abroad by reason of the cold, and so leave but few signs of themselves? Therefore some say, beasts spare the neighboring places, that they may not be sore put to it by going far abroad in winter, but may always have food ready at hand.

Or is it because that for hunting the track alone is not sufficient, but there must be scent also? And things gently dissolved and loosened by heat afford a smell, but too violent cold binds up the scent, and will not let it reach the sense.
