Placing work and commerce near residences, but buffering it off, in the tradition set by Garden City theory, is fully as matriarchal an arrangement as if the residences were miles away from work and from men. Men are not an abstraction. They are either around, in person, or they are not. Working places and commerce must be mingled right in with residences if men, like the men who work on or near Hudson Street, for example, are to be around city children in daily life—men who are part of normal daily life, as opposed to men who put in an occasional playground appearance while they substitute for women or imitate the occupations of women.
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.
