Lumber companies, which make their money on trees, depend on those that grow quickly. Therefore, they are always looking for methods to make trees grow faster. So far, the secret to fast growing trees seems to lie in "super-seeds." These are seeds that are gathered from the quickest growing trees in a forest. One company searched 100,000 acres of trees and selected the seeds from just fifteen trees. These two ounces of seed were enough to plant several hundred new trees. Eventually, when these trees have grown, seeds will again be taken only from the fastest growing trees of crop.

National characteristics are not easy to pin down, and when pinned down they often turn out to be trivialities or seem to have no connection with one another. Spaniards are cruel to animals; Italian can do nothing without making a deafening noise; the Chinese are addicted to gambling. Obviously such things don’t matter in themselves.

They have a horror of abstract thought; they feel no need for any philosophy or systematic ‘world-view’. Nor is
