Happy grass is happy

"Marram Grass is often found on coastal dune systems - where plants have adapted to cope with a potential dearth of fresh water - so they have to be fairly economical with the fresh water they do have access to.

This is a cross section of the leaf. It has a tough exterior, it is rolled along its length and the interior side is covered in fissures and hairs. The purpose of these features is to minimise the airflow over the stomata - the apertures where gas exchange occurs - which are buried in the area shown in blue on this image. When the stomata open, the plant can take carbon dioxide from the atmosphere, but it loses water through transpiration. Transpiration is an important process and the plant can regulate it in dry environments through adoptions such as those displayed in this image."
Of course, if there were a spider on this grass, it would have to be this spider:

Theridion grallator, also known as the “happy face spider,” is a member of the Theridiidae family.

The Hawaiian name is nananana makakiʻi (face-patterned spider). The binomial grallator is Latin for “stiltwalker”, reference to the species’ long spindly legs...

As the pattern may change according to what food the spider has eaten (Gillespie, 1989) and as T. grallator is very small, hides during the day, and is thus not a significant prey item for any species of predator, it is more likely that the bizarre variety of patterns serves no significant adaptive purpose at all.
Spider via animals, animals, animals.

Update:  I think I finally found the source for the photo - Phil Gates at Beyond The Human Eye, a microscopy blog that appears to have a lot of interesting content.

What the Donner party ate


Excerpts from a column at Discovery News:
A new book analyzing one of the most spectacular tragedies in American history reveals what the 81 pioneers ate before resorting to eating each other in a desperate attempt to survive. On the menu: family pets, bones, twigs, a concoction described as "glue," strings and, eventually, human remains.

The book, "An Archaeology of Desperation: Exploring the Donner Party's Alder Creek Camp," centers on recent archaeological investigations at that campsite near Truckee, Calif., where one quarter of the 81 emigrants spent their nightmarish winter of 1846-47...

Co-editor Kelly Dixon, an associate professor in the Department of Anthropology at The University of Montana, told Discovery News that she and her colleagues "are emphasizing the fact that the historical and archaeological sources present a complicated story about humans doing whatever possible, including eating hide and strings as well as consuming their dogs, before making the desperate decision to cannibalize..."

Dixon and co-editors Julie Schablitsky and Shannon Novak identified rodent, canine, deer, rabbit, horse and oxen/cattle bones within the over 16,000 bone fragments...

The historical record, consisting of letters and journals kept by members of the Donner Party and rescue groups, as well as the memories of some survivors, supports that the trapped members first ate all of their animals, including captured mice and the family dogs, as well as wild game.

Of the family dog "Cash," emigrant Virginia Reed Murphy wrote, "We ate his head and feet -- hide -- every thing about him."..

Johnson reports that James Frazier Reed, who left and then returned with men to help at Jacob Donner's camp, "found a gruesome scene."

Hair, bones, skulls, and the fragments of half-consumed limbs were said to be around the fire. Jacob Donner's body was found with his heart and liver removed and his limbs and arms cut off. Another account describes children having blood on their faces, after trying to consume such flesh.

Addendum:  My thanks to  Phillip Sexton, District Interpretive Coordinator for the Capital District of California State Parks, who reviewed this post and offered the following information [boldface added by me]-
I’ve attached a screenshot [bottom] from Google Earth showing the relationship between the George/Jacob Donner campsite , a USFS facility that I had connections with and Donner Memorial State Park. The Donner family was actually not at the lake; they never made it that far because one of their wagons broke an axle at this point. If I recall correctly, George Donner was limbing a lodgepole pine (common in this area) for a new axle and cut his arm quite badly, so they were stuck. Eventually, George developed Gangrene and died. Tamsen Donner, his wife, remained with George even after rescuers arrived. She sent her children to safety and they survived, but Tamsen died sometime after George.

A German immigrant, Lewis Keesburg, was part of this party and if memory serves, he and Phillipa, his wife, were camped at the Donner lake site. Keesburg admitted to cannibalism of (I think) both George and Tamsen as a way to survive.

Keesburg was not well liked in that party, and of course his admission of cannibalism didn’t help him fit in with early Sacramento society. When he arrived at Sutter’s Fort in the spring of 1847, Sutter hired him as a clerk of some sort. Later on, in an incredibly poor business decision by someone in 1850s Sacramento, he was hired to manage a restaurant in a building that still exists in Old Sac, called the Lady Adams building. Newspaper accounts state that he was followed down the street by children and presumably others who would taunt him. The restaurant of course, failed.

This all sounds quite awful, but Keesburg was not a nice man. His grave is unknown because when he died in the charity hospital he was interred in an unmarked grave. Later on, McKinley Park was developed on the site, and charity interments were disinterred and I’m told put into a mass grave in the old City Cemetery on Broadway in Sacramento. Phillippa, his wife, is buried in this cemetery. She divorced her husband due to his physical cruelty toward her, which, for this to have been a reason in the 19th century, had to be awful, and quite well documented.

Oddly enough, I found comments that I made in a Google Earth forum in 2006 that comment on the discoveries that were made by the Discovery TV show crew, which probably shot there in 2005.  The most significant discovery was that the actual Donner campsite where a lean-to was built against a tree, was not where everyone since the 1920s had thought it was. I won’t share the exact location, but it’s about 100 yards from where it was thought to be. This was confirmed due to an ash/midden pile where many of the bones referenced were found. The 1920s location was determined by an amateur historian named Patrick Weddel, who mapped, mostly accurately but with some bad assumptions, the trail. The Donner diaries describe the leanto against a large “wolf” tree, and Waddel found a very large Jeffery pine that was of the right age and it had a fire scar, so that was his determination. Good guess, and the science wasn’t developed then, but he wasn’t correct. Close but no cigar.

In 2006 when this all came out at an Archeological meeting, the whole thing was somewhat misconstrued, I think due to the passion that people have for history. It clouds some people’s judgement, so you started seeing assertions that cannibalism did not happen, such as at this link. The report actually says no such thing; the discoveries made in 05 indicated that their diets were more complex than previously known, but there were admissions by participants (such as Keesburg) that they consumed human flesh.

The comment by your reader “TD” is simply a bomb thrown by an ignorant person. Members of the group did in fact try fishing as well as setting traps, and they were remarkably unsuccessful, which leads me to one of my grand theories that I throw out only for thought, but it fits my grand theory of life:

The Donner Reed party, when you look at the sum total of their experiences, made nearly every single stupid decision that they could have made, from starting late, taking Hastings cutoff, pausing to rest when it was late in the season, ultimately camping in three disparate locations near the lake (there is a third known site basically on I-80 today) and so forth. They also chose a very poor leader. George Donner was affable and friendly, but was not a leader. James Reed would have been a far better leader, but his arrogance and hubris prevented that, so the entire party suffered mightily. All of this was known of pretty quickly in the spring and summer of 1847 and stories spread around the US and around the globe. Also, I want to emphasize that I’m not demeaning these people or criticizing them. All of us have had things go south and then later on thought “what was I thinking?” At the time, the decisions they made seemed to make sense, and I can understand that.

In the same year that the Donner Reed party emigrated, a man named T.H. Jefferson also was an emigrant, and in fact he interacted with the Donner Party. Many people feel that he was a descendant of Thomas Jefferson, but its not known. He drew a remarkable map in four sheets, of the emigrant trail, that was published in 1848. Jefferson’s map is remarkable, and it was essentially the AAA map of its day. It has mileage between campsites and very helpful notations. On the LOC map, zoom in on the sheet showing the crossing over the Sierra and read the very prescient notation about the Donner-Reed party and conditions crossing the mountains.

But I digress. Between stories of the Donner-Reed party and exemplars like the Jefferson map, I really believe that the stories and information about the Donner party helped save the lives of perhaps thousands of hapless people who came overland to CA but who were tenderfeet. The Donner experience served as a list of things NOT TO DO and in a karmic sense, I think served a greater good in the long run, but of course that’s just my personal opinion.

The "Warsaw Concerto"


I heard this while driving today; it has a number of very familiar passages which I'm sure I"ve heard a dozen times, but couldn't remember where.  It sounds like it should be soundtrack from Brief Encounter, but a quick search reveals that it was composed by Richard Addinsell for the 1941 British movie, Dangerous Moonlight.
The film-makers wanted something in the style of Sergei Rachmaninoff's Rhapsody on a Theme of Paganini or the Second and Third Piano Concertos, but were unable to persuade Rachmaninoff himself to write a new piece or to afford to obtain the rights for any of these existing pieces. The music was later used in another film, The Sea Wolves (1980)... 
I've not seen either of those movies.  I suspect my familiarity with it stems either from this: "The Concerto is frequently used in championship figure skating (especially in Japan)" or from its use as a filler for 10-minute spaces in classical music radio programming.

And now I can't resist reposting that parody of the closing scene of Brief Encounter.

Brief Encounter



The closing six minutes of the famous David Lean film. Celia Johnson parting from Trevor Howard, then returning to her husband, all to the music of Rachmaninoff's second Piano Concerto.

This is absolutely one of my favorite movies of all time, and winner of the Palme d'Or at Cannes in 1946, and #2* in the British Film Institutes list of the Top 100 British Films.

There are excerpts of many of the iconic moments from the film available on YouTube. The one embedded above is the tear-jerking finale. For a total (and refreshing, for film buffs) change, try the parody embedded below, starring Victoria Wood. It's exceptionally well done.

"Chocolate pud"

This is reportedly world's most expensive dessert, with the eye watering price tag of £22,000. Styled like a Faberge Easter egg, the extravagant chocolate pud is believed to have broken all previous records thanks to its pricey list of ingredients which includes gold, champagne caviar and a two carat diamond. Layered with champagne jelly and a light biscuit joconde, the creation is finished with bitter dark chocolate and glazed with edible gold leaf. It has been created by Marc Guibert, head chef at Lindeth Howe Country House Hotel in Windermere, Cumbria.
In an effort to learn something while posting this, I looked up the history of pudding:
It seems that the ancestor of the term was the Latin word botellus, meaning sausage, from which came boudin and also pudding... Though time, many different kinds of foods have been known by this name. The creamy, rich pudding dessert we (Americans) think of today is more closely related to custard...

Food historians generally agree the first puddings made by ancient cooks produced foods similar to sausages... Medieval puddings (black and white) were still mostly meat-based. 17th century English puddings were either savory (meat-based) or sweet (flour, nuts & sugar) and were typically boiled in special pudding bags...

The distinction between European custard and American pudding became muddled sometime in the 1840s. At that time in America, traditional boiled puddings were no longer necessary to feed the average family. There was plenty of food. This also happened to be the same time when Alfred Bird, an English chemist, introduced custard powder as an alternative to egg thickeners. It wasn't long before Americans began using custard powder and other cornstarch derivatives as thickeners for custard-type desserts. This proved quite useful for overlander (conestoga wagon) cooks who did not have ready access to a reliable supply of fresh eggs...

A day in the life of a college quarterback

The Wall Street Journal offers an excerpt from a book about the football program at the University of Michigan.  A day for superstar quarterback Denard Robinson is described as hectic and exhausting.  Herewith an summary:

0630 - to the sport facility
1000 - attend a class (80 minutes long)
Lunch at a restaurant
One-hour meeting with a professor to discuss a paper
1400 - return to athletic facility
1930 - dinner
Watch films of game
2230 - leave athletic facility
2300 - to bed

Why don't they just pay these guys as performers and stop the charade of pretending they are students. 

p.s. - I note the athletics refer to nonathlete students as "normies."

High-speed photos of splashing liquid

From a gallery of photos of splashing liquid, by Markus Reugels

A memorable first line

\
“Francis Marion Tarwater’s uncle had been dead for only half a day when the boy got too drunk to finish digging his grave and a Negro named Buford Munson, who had come to get a jug filled, had to finish it and drag the body from the breakfast table where it was still sitting and bury it in a decent and Christian way, with the sign of its Savior at the head of the grave and enough dirt on top to keep the dogs from digging it up. Buford had come along about noon and when he left at sundown, the boy, Tarwater, had never returned from the still.”
Text via First Lines, an interesting tumblr blog comprised exclusively of first lines from books.   That text comes from The Violent Bear It Away, written by Flannery O'Connor, pictured above as an adult when she needed crutches to help her cope with the ravages of lupus.

Here's an excerpt from her biography:
O'Connor described herself as a "pigeon-toed child with a receding chin and a you-leave-me-alone-or-I'll-bite-you complex." When O'Connor was six she taught a chicken to walk backwards, and this led to her first experience of being a celebrity. The Pathé News people filmed "Little Mary O'Connor" with her trained chicken, and showed the film around the country. She said, "When I was six I had a chicken that walked backward and was in the Pathe News. I was in it too with the chicken. I was just there to assist the chicken but it was the high point in my life. Everything since has been anticlimax.”
The photo below shows her reading at about that age -


Photo found at Printed and Bound, via Uncertain Times, which included this marvelous quote:
“Everywhere I go I’m asked if I think the university stifles writers. My opinion is that they don’t stifle enough of them.”
Flannery O'Connor died at age 39 in 1964 as I was heading off to college.  Two years later I encountered her work in a course on American Southern writers, and eagerly read her two novels and most of her short stories.

(Originally posted February, 2010. Today I found a nice biography of her in the New Georgia Encyclopedia.)

"Child sacrifice" in modern-day Africa

Excerpts from a report at the BBC:
The villages and farming communities that surround Uganda's capital, Kampala, are gripped by fear. Schoolchildren are closely watched by teachers and parents as they make their way home from school... The mutilated bodies of children have been discovered at roadsides, the victims of an apparently growing belief in the power of human sacrifice...

Many believe that members of the country's new elite are paying witch doctors vast sums of money for the sacrifices in a bid to increase their wealth.

"Child sacrifice has risen because people have become lovers of money. They want to get richer," the pastor says. "They have a belief that when you sacrifice a child you get wealth, and there are people who are willing to buy these children for a price. So they have become a commodity of exchange, child sacrifice has become a commercial business."..

[UK-based charity, Jubilee Campaign] says in a report that the true number of cases is in the hundreds, and claims more than 900 cases have yet to be investigated by the police because of corruption and a lack of resources...

Clarke and Dawe explain Europe's monetary crisis


The striking thing is that this skit was performed in May of 2010.  And it still is relevant.

This is not an optical illusion

The nail passes through a hole in the two center "teeth" of the wooden block.  It's more-or-less in the center, parallel to the long axis of the block - not at a significant angle.

The nail is a normal carpentry item that has not been modified in any way (not cut and reassembled).

The wood is normal wood; the three notches were cut in a solid block of wood before the nail was inserted.  The wood has not been broken apart or glued together.

How was this done?  See if you can puzzle out the method before viewing the solution in the video below.  Credit to the Steve Ramsey at Woodworking for Mere Mortals, via within the crainium. YouTube link.
