The remaining seventy miles lie in a clearrolling country mostly under cultivation. With the exception of afew angles near Guanajuato, the line is almost straight. Threemethods of construction were available: wood poles, iron poles andtowers. Since native timber is not durable enough for pole line pur-poses, and Texas timber is expensive to import, many high-tensionlines in Mexico are built of tubular steel poles. As the line was one of the vital points of this installation, it wasdesirable to make it both electrically and mechanically as strong anddurable as possible. Each insulator of a high-tension line is liableto puncture and breakage, and is, therefore, a point o
