The article also noted that 10,000-year-old cultivated squash seeds had recently been reported in Mexico, along with evidence of domesticated corn there by 9,000 years ago. Scholars now think that plants were domesticated independently in at least 10 “centers of origin,” including, in addition to the Middle East, Mexico and Peru, places in Africa, southern India, China and New Guinea.

In the Fertile Crescent of the Middle East, an arc from modern-day Israel through Syria and Turkey to Iraq, wheat and barley were domesticated by 10,000 years ago, and possibly rye by 13,000 years ago. Experts in ancient agriculture suspect that the transition from foraging to cultivation had started much earlier and was not as abrupt a transformation as indicated in the archaeological record.

The distribution of building structures, canals and furrowed fields, Dr. Dillehay said, indicated that the Andean culture was moving beyond cultivation limited to individual households toward an organized agricultural society.

“One of the best management techniques for controlling Goss’s wilt is crop rotation — corn, then soy or another crop,” Mr. Anderson said.

nother possible factor is the growth of no-till farming, which leaves cornstalks, on which the bacteria can linger, to decay in the field after harvesting, rather than being plowed under.

The next headache should be contagion.

What has been offered to Greece cannot be refused to other Eurozone governments

An alternative to spreading mutual underwriting is debt monetisation.

The ECB does not buy assets outright, so the loss would be borne by the banks that used the Greek bonds as collateral for repo operations with the ECB. But banks are the ECB’s counterparties; if they default, the loss is the ECB’s.

Was there no other way? It would have been very easy to let Greece go straight to the IMF months ago and reschedule its debt with IMF’s assistance. This would have been a partial default, and the haircut could have been quite small. Most banks that are exposed to the Greek debt should have been able to withstand such losses. With a grace period of, say, three years, Greece would have had the breathing space that the latest plan tries so hard to organise

The logs are shipped to a mill in San Leandro, California.

The slats are waxed and kiln dried again.

The cedar logs are cut into small, pencil-length slats less than one-fourth of an inch in thickness. These are kiln dried and then tinted for the same reason women put rouge on their faces.

Don't overlook the ancestors present and distant who have a hand in transporting sixty carloads of slats across the nation.

Once in the pencil factory—$4,000,000 in machinery and building, all capital accumulated by thrifty and saving parents of mine—each slat is given eight grooves by a complex machine, after which another machine lays leads in every other slat, applies glue, and places another slat atop—a lead sandwich, so to speak. Seven brothers and I are mechanically carved from this "wood-clinched" sandwich.

The graphite is mined in Ceylon.

The graphite is mixed with clay from Mississippi in which ammonium hydroxide is used in the refining process. Then wetting agents are added such as sulfonated tallow—animal fats chemically reacted with sulfuric acid. After passing through numerous machines, the mixture finally appears as endless extrusions—as from a sausage grinder-cut to size, dried, and baked for several hours at 1,850 degrees Fahrenheit. To increase their strength and smoothness the leads are then treated with a hot mixture which includes candelilla wax from Mexico, paraffin wax, and hydrogenated natural fats.

My cedar receives six coats of lacquer. Do you know all the ingredients of lacquer? Who would think that the growers of castor beans and the refiners of castor oil are a part of it? They are.

Observe the labeling. That's a film formed by applying heat to carbon black mixed with resins. How do you make resins and what, pray, is carbon black?

My bit of metal—the ferrule—is brass. Think of all the persons who mine zinc and copper and those who have the skills to make shiny sheet brass from these products of nature. Those black rings on my ferrule are black nickel. What is black nickel and how is it applied? The complete story of why the center of my ferrule has no black nickel on it would take pages to explain. RP.18

An ingredient called "factice" is what does the erasing. It is a rubber-like product made by reacting rape-seed oil from the Dutch East Indies with sulfur chloride. Rubber, contrary to the common notion, is only for binding purposes. Then, too, there are numerous vulcanizing and accelerating agents. The pumice comes from Italy; and the pigment which gives "the plug" its color is cadmium sulfide

Actually, millions of human beings have had a hand in my creation, no one of whom even knows more than a very few of the others.

There isn't a single person in all these millions, including the president of the pencil company, who contributes more than a tiny, infinitesimal bit of know-how.

Here is an astounding fact: Neither the worker in the oil field nor the chemist nor the digger of graphite or clay nor any who mans or makes the ships or trains or trucks nor the one who runs the machine that does the knurling on my bit of metal nor the president of the company performs his singular task because he wants me.

There is a fact still more astounding: the absence of a master mind, of anyone dictating or forcibly directing these countless actions which bring me into being. No trace of such a person can be found.

For, if one is aware that these know-hows will naturally, yes, automatically, arrange themselves into creative and productive patterns in response to human necessity and demand—that is, in the absence of governmental or any other coercive masterminding—then one will possess an absolutely essential ingredient for freedom: a faith in free people. Freedom is impossible without this faith.

From a standing start, China now has 12% of graduates in the world's big economies - approaching the share of the UK, Germany and France put together. The incumbent superpower, the United States, still towers above with 26% of the graduates.
