High dams of great length

When an engineer undertakes a special study of any kind, he usually finds that certain considerations vitally affecting the problem before him have not received quite as much attention as their importance demands, and he sometimes finds, too, a new path of study, or investigation, or some neway of applying well established principles. In both cases he may gain much by putting his views before his fellows, and their opinions and criticisms will help to put these matters in the true perspective, to confirm or correct his opinion as regards what he thinks has been neglected or not fully grasped, and to point out where his new path has already been well trodden or where it leads to an impassable chasm.
