Question 21-31
Legend has it that sometime toward the end of the Civil
War (1861-1865) a government train carrying oxen traveling
through the northern plains of eastern Wyoming was caught in
a snowstorm and had to be abandoned. The driver returned
the next spring to see what had become of his cargo. Instead
of the skeletons he had expected to find, he saw his oxen,
living, fat, and healthy. How had they survived?
The answer lay in a resource that unknowing Americans
lands trampled underfoot in their haste to cross the "Great
American Desert" to reach lands that sometimes proved
barren. In the eastern parts of the United States, the preferred
grass for forage was a cultivated plant. It grew well with
enough rain, then when cut and stored it would cure and
become nourishing hay for winter feed. But in the dry grazing
lands of the West that familiar bluejoint grass was often killed
by drought. To raise cattle out there seemed risky or even
hopeless.
Who could imagine a fairy-tale grass that required no rain
and somehow made it possible for cattle to feed themselves all
winter? But the surprising western wild grasses did just that.
They had wonderfully convenient features that made them
superior to the cultivated eastern grasses. Variously known as
buffalo grass, grama grass, or mesquite grass, not only were
they immune to drought; but they were actually preserved by
the lack of summer and autumn rains. They were not juicy
like the cultivated eastern grasses, but had short, hard stems.
And they did not need to be cured in a barn, but dried right
where they grew on the ground. When they dried in this way,
they remained naturally sweet and nourishing through the
winter. Cattle left outdoors to fend for themselves thrived on
this hay. And the cattle themselves helped plant the fresh
grass year after year for they trampled the natural seeds
firmly into the soil to be watered by the melting snows of winter
and the occasional rains of spring. The dry summer air cured
them much as storing in a barn cured the cultivated grasses.
