I'm standing there guarding cattle. Psych!
It was an early departure, and the
ranger was waiting for us to clear the gate so he could get in with a truckload
of maintenance materials, so I just had time to grab a couple quick
pictures. That accounts by my shadow in
the picture. Anyhow, I chuckle every
time I see one of these any more. This
is a cattle guard. For those not
familiar with them, it is a pit across the drive where a gate would otherwise
have to be. It is to keep cattle in a
field where they graze free, but where vehicles have to frequently travel
without always having to open and close the gate. The pit is covered with a bridge of pipes
that have spaces between them. The
spaces are narrow enough that a vehicle can drive across them, but wide enough
that the cattle fear getting their legs trapped, so they rarely attempt going
out of the opening in the fence line.
The humor comes from a line budget hearing Pres. George W. Bush was
having with the Department of the Interior.
They have a lot of open public lands that cattlemen are permitted to use
for grazing, but which have to be open to public access, so all the roads have
cattle guards in the fences. Pres. Bush
saw the line for cattle guards, and wanted to know why the government had to
pay men to guard privately owned cattle.
Having a farm in Texas, famous for its cattle industry, one would think
he would have known what a cattle guard was without having to have it
explained, but……oh, well.
Early powered thresher. The large pipe turned back over the machine
was turned out over open ground and discharged chaff from the threshing
operation.
This is a very nicely preserved steam
thresher. Harvesting grain involves
three steps: reaping, threshing, and winnowing.
Reaping is cutting the grain.
Originally, all of this grain would have to be bundled and carried back
to the barn. There it was beaten on the
threshing floor, which knocked the grain loose from the plants, but a lot of
bran, or chaff (broken plant bits), remained mixed with the grain. This had to be winnowed. A basic process would be to throw shovels
full of grain into the air. The breeze
would carry the chaff and dirt away, and the heavier grain would fall back onto
the threshing floor to be bagged. In
1789 a Scottish engineer devised a mechanical thresher that allowed the
operations of threshing and winnowing to be done more quickly, but since these
were stationary threshers, the grain still had to be carried back to the barn
where the thresher was set. Here is a
steam-driven mobile thresher. Before gas
tractor engines were common, farm machinery was powered by steam engines. The long tongue in front was used to pull the
threshing machine into the field with a steam tractor or a team of horses. Allowing threshing to be done right in the
field permitted farmers to follow the grain cutting operation through the
fields and do the threshing and winnowing on site without having to haul all
the grain back to the barn. A steam
engine would be set nearby, and long belts, which you can see rolled and
carried in a rack on the side of the thresher, were run between a power wheel
on the steam engine and the drive wheel on the thresher. Steam engines are extremely dangerous for
those inexperienced in their use, and boiler explosions frequently injured and
killed farm workers. My father was a
fireman on steam locomotives on the Pennsylvania Railroad, so being an expert
in steam power, he always had non-stop employment every harvest season. The threshing work is now done by the combine
harvester, which is engine powered, and as the name implies, now performs all
three harvesting operations simultaneously.
