### A Texan farmer goes to Austral...

A Texan farmer goes to Australia for a vacation.
There he meets an Aussie farmer and gets talking.
The Aussie shows off his big wheat field and the Texan says, "Oh! We have wheat fields that are at least twice as large."
Then they walk around the ranch a little, and the Aussie shows off his herd of cattle. The Texan immediately says, "We have longhorns that are at least twice as large as your cows."
The conversation has, meanwhile, almost died when the Texan sees a herd of kangaroos hopping through the field. He asks, "And what are those?"
The Aussie replies with an incredulous look, "Don't you have any grasshoppers in Texas?"

### Centre-pivot irrigator

In 1952, a U.S. patent for a "Self-Propelled Sprinkling Irrigating Apparatus" was issued to Frank L. Zybach of Strasburg, Colorado (No. 2,604,359). A centre-pivoted pipe supported on a series of water-piston-powered wheels rotates and sprinkles water on the crops.A control system ensures that each wheel advances at the correct rate. This is the now-familiar centre-pivot machine that waters large circles of crops in those areas of a country which have limited rainfall but have a supply of surface or well water. It provides irrigation for large areas of even closely-spaced crops for which irrigation ditches are not practical and wasteful of water, or that would be expensive to supply with full coverage with stationary sprinklers.«[Image: a modern example showing the sprinkler pipe carried above a series of large wheels.]
