Types of Bears

A married couple was vacationing in Yosemite Park in the United States. The wife expressed her concern about camping because of bears and said she would feel more comfortable in a motel. The husband said he would like to camp outside in the woods. To calm her concerns, he suggested they talk to the park ranger to see what the likelihood of a bear encounter would be.

The ranger told them, "Well, we havewn't seen any grizzlies in this area so far this year, or black bears, for that matter."

The wife shrieked, "There are TWO types of bears out here? How can you tell the difference? Which one is more dangerous?"

The ranger replied, "Well, that's easy -- see, if the bear chases you up a tree and it comes up after you, it's a BLACK bear. If it SHAKES the tree until you fall out, it's a grizzly."

The motel room was quite nice.

Ice cream freezer

In 1843, a U.S. patent was issued, antedated to 29 Jul 1843, for a hand-cranked ice-cream freezer invented by Nancy M. Johnson (No. 3,254). In previous designs, the ice-cream mixture was held in an inner container, which vessel was itself was rotated within an outer container of ice and salt. Her invention was to add a vertical shaft with curved, perforated paddles within the inner vessel, and reaching nearly to its inside wall. Stirring in one direction would carry the the liquid or semi-fluid mass from the centre to the circumference. Turning in the opposite direction would scrape frozen material and carry it from the inner walls to the centre of the freezer. Thus fresh matter continuously reached the freezing surface.«[Image: detail from patent diagram showing inner container and its paddle.]
