Q Well, were there nineteen different plottings on this one sheet ( indicating)? Mr, Fransworth. That is how many? The Witness. Well, for each measurement all of these factors can be obtained from it. I can determine the dis-charge; I can determine the cross- section; I can determine the mean velocity; I can determine the maximum velocity; and I can determine the mean flow. Each measurement used showed me all of those things. Now, approximately we make 365 measurements a year at Lees Perry. Since 1921 there have been thousands of measure-ments made, from which any one of these points could have been determined. I took simply those measurements for 1921 and 1922 to show a picture. I could have taken 1921, 1923, 1927 and 1928 -- any one of the thousands of others -- as long as I had a composite picture there, high water and low water in all seasns.
