Before we go any farther, I ask you to rise and join me in giving three cheers for that great Conservationist, Captain White.

Three rousing cheers were given, led by Mr. Pack.

Mr. White—Ladies and Gentlemen, Delegates to the Congress, Mr. President: This is glory enough for me. I feel paid for the work I have done in the past year in having the appreciation of such a good class of people. (Applause.)

President Pack—The next speaker on the program is Mr. George M. Lehman, representing the Mayor of Pittsburgh, who will speak to us on “The Investigations of the Flood Commission of Pittsburgh.”

Address, “The Investigations of Flood Commission of Pittsburg”

Mr. Lehman—Mr. Chairman and Delegates of the Fourth National Conservation Congress: It has been the custom in this country to build dams and locks on lower reaches of rivers, for navigation; to build regulating works for forming and maintaining channel depth, etc., and to dredge deposits caused by erosion.

Our country has received large benefit from this process, particularly in certain sections. It would have thrived, however, to a far greater extent and much suffering, involving general living and business conditions, would have been avoided and a better foundation provided for future generations, if, in addition to the above-named developments, attention had been promptly and thoroughly given to the control and conservation of flood water. We have been woefully thoughtless and backward in bringing about a comprehensive treatment of this matter which is of such great national importance.

HISTORICAL AND GENERAL OUTLINE OF WORK.

Pittsburgh having been seriously troubled by destructive floods for over a century, attention was finally directed toward means of alleviation and in 1908 the Chamber of Commerce organized a commission consisting of business men, engineers and other professional men, to ascertain the character and extent of flood damage and make investigations of methods for relief. Later, an enlargement of the commission was made by the addition of city and county officials and representatives of manufacturing and various business concerns affected by floods. The expense of carrying on the work has been borne by public-spirited citizens, including the interests affected by the floods, and by county and city contributions. To this date about $137,000 has been expended.

The work has involved detailed surveys and soundings, within the city limits, of the Ohio, Allegheny and Monongahela Rivers, and a survey of the areas of overflow. The topography was fully developed, and streets, lines of transportation, buildings, etc., located. Extensive topographic surveys were made along the principal tributaries of the Allegheny and Monongahela Rivers for the purpose of determining the possibility of constructing storage reservoirs.
