Hardy Books

“As he bit into the oily green flesh, Fairchild couldn't have known he was holding in his hands the future crop of the American Southwest. But he had a hunch. It was a black-skinned fruit, a variety of alligator pear, or as the Aztecs called it, "avocado," a derivative of their word for testicle. It grew in pairs, and had an oblong, bulbous shape. The fruit had the consistency of butter and was a little stringy. But unlike the other avocados he had tasted farther north, in Jamaica and Venezuela, this one had remarkable consistency. Every fruit on the tree was the same size and ripened at the same pace, rare qualities for anything that grew in the consistent warmth of the subtropics.
In Santiago, where a boat had deposited Fairchild and Lathrop, the avocado had an even greater quality. Fairchild listened intently as someone explained that the fruit could withstand a mild frost as low as twenty-three degrees Fahrenheit. Such a climatic range suggested a perfect crop for America. From central Mexico, the worldwide home of the first avocados, centuries of settlers had carried the fruit south to Chile. David Fairchild mused about taking it the other way, back north. "A valuable find for California," he wrote. "This is a black-fruited, hardy variety."
Lathrop tagged along on the daytime expedition when Fairchild tasted that avocado. He agreed that a fruit so hardy, so versatile, would perfectly answer farmers' pleas for novel but undemanding crops, ones that almost grew themselves, provided the right conditions. Fairchild didn't know the chemical properties of the avocado's fatty flesh, or that a hundred years in the future it would, like quinoa, find esteem, owing to its combination of fat and vitamins. But he could tell that such a curious fruit, unlike any other, must have an equally curious evolutionary history. No earthly mammal could digest a seed as big as the avocado's, and certainly not anything that roamed wild through South America.”
