Branding cattle may evoke images of the old west a century ago, but it’s a still-active part of agriculture in the North Bay, with a lengthy history here, too.

Just as they were a century again, brands are used today to identify the legal owners of not just cattle, but horses, mules, burros, sheep and swine.

Ernie Ongaro (right) grew up on his family’s ranch along San Anselmo Creek, and began helping with the livestock branding at the age of 10. These days, he lives and raises beef cattle southwest of Sebastopol. Over the years he’s seen many familiar local brands go inactive (but his book includes both active and inactive brands from Marin and Sonoma counties). He’s also seen the shady practice of “overbranding” employed all the way into the present day.

You can see an array of sample brands below.

As seasoned baseball fans know, there's considerably more going on between the lines on the diamond than may be readily apparent.

Paul Dickson (right)  has written  more than 50 non-fiction books and countless articles on subjects from toasting to ice cream to baseball to slang to Sputnik. He says he wrote this book because he became interested in learning more about the "covert aspects" of the game of baseball.

One way in which modern major league baseball differs from the game of years past is the role of the umpires. Dickson says they are now coached to maintain a much lower profile than they once maintained.

A new analysis finds there are fewer foggy days along the Northern California coast than there were  100 years ago. That’s bad news for the venerable coast redwoods.

In addition to charting a reduction in the number of foggy days over the past century, U.C. Berkeley researcher Todd E. Dawson says their study also found fewer hours of foggy conditions on the days when the mist was present.

In their analysis, Dawson and  his colleague, James Johnstone, found there was a relationship between drought years and fog conditions, but it’s not what one might expect.
