Texan Farmer Travels

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 asks with an incredulous look, "Don't you have any grasshoppers in Texas"?

Screw pointing and threading machine patent

In 1852, Cullen Whipple, of Providence, R.I., patented his "Mechanism for Pointing and Threading Screw-Blanks in the Same Machine" (U.S. No. 9477). His new design incorporated additional cutters in the same threading machine he had patented on 18 Aug 1842 (No. 2754, reissued 5 Mar 1850). Before machines provided a point on screws, they had blunt ends, and it was necessary to drill a starter hole. In Oct 1840, he was one of ten incorporators of The New England Screw Co. After his original thread-cutting machine, he invented another for shaving the heads of screws (patented 6 Apr 1843) and one for removing the burs left in cutting the slots in the heads (patented 19 Apr 1843). He patented seven other screw-manufacturing devices.«
