Progress in Dams and Pipe Lines

augurating similar reports for itself this year has wisely divided the field among several speakers and the present speaker has been assigned dams and pipe lines. There is some overlapping since distribution which is largely pipe lines has been included in the assignment of Mr. Brush and pipe lines are included also in the speaker's assignment. Probably a difference in point of view will prevent real interference, and as pipe lines constitute more than half of waterworks they are worthy of double attention. The wording of the subject appears to confine the scope of the statements to progress during the year, meaning one would suppose, progress since May of 1934. Practically, no fixed period can be taken since progress is generally of slow growth and consists in the gradual adoption of improved designs or methods so that it may be observed best by a comparison extending over a decade or more rather than only a 12-month. It is generally impossible even for a thorough student of current literature which the speaker is not to detect when a new method becomes so well proved that it may be surely called progress and not merely novelty.
