Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
This type of beauty grows with each passing day. Utilitarian craftwares become more beautiful the more they are used, and the more beautiful they become, the more they are used.
Moreover, the heavens have ordained that these objects should attain an even greater beauty as they become worn by the handling of human hands.
Miscellaneous handicrafts are devoid of ambition. Their purpose is to serve the needs of the people, not to achieve renown. Just as construction workers who have built a wonderful highway don’t sign their work, neither do artisans append their names to their ware. From beginning to end, without exception, such handicrafts are made by nameless craftsmen. It is this lack of desire for personal recognition that produces their flawless beauty.
Rather than the craft object finding the most suitable material, it can be said that the material finds the right object. Folk crafts are invariably the product of a local environment. When a certain locality is rich in a certain raw material, that material gives rise to a certain craftware.
Nature tells us the shape and pattern a material should assume, and nothing good can be achieved by ignoring its dictates. A good artisan seeks nothing that nature does not seek.
