I notice that cows never walk abreast, but in single file commonly, making a narrow cow-path, or the herd walks in an irregular and loose wedge. They retain still the habit of all the deer tribe, acquired when the earth was all covered with forest, of travelling from necessity in narrow paths in the woods.
At sundown a herd of cows, returning homeward from pasture over a sandy knoll, pause to paw the sand and challenge the representatives of another herd, raising a cloud of dust between the beholder and the setting sun. And then the herd boys rush to mingle in the fray and separate the combatants, two cows with horns interlocked, the one pushing the other down the bank.
My grandmother called her cow home at night from the pasture over the hill, by thumping on a mortar out of which the cow was accustomed to eat salt.
