Show ( fiho 'the the ) ( cuiSi'G cuiSiG ) water in , ( ifiebas'i'll ifiebasill ) ( 70 76 ) runs off during one month . Now , the tables on pages 40 , ( 41 4-1 ) , and 42 are ( espe espe- espe ) cially illuminating , in that they show , for ready Teferencey the flow by months , in order that they may be compared with the same flow for the same ( months nioliths ) in another year . In this particular case , I think they are very important . For instance , on page 42 is shown the mean ( run-off runoff ) of the Colorado River at Lees Ferry , for the month of September 1921 to ( 1928 1.928 ) . 1921 was the period in which all of the river surveys were made . The topographers were working ( 011 on ) the river . ( In Iii ) 1922 ( , ) ) ( he lie ) believes they have a record of the river asnoticed by the party of engineers who made a trip ( from ftom ) Halls Crossing to Lees Ferry . The ( Stabler-LaRue StablerLaRue Stabler-La-Rue StablerLaRue ) party . The table showsthat during 1921 the ( mean ineall ) flow was 12,500 ( second-feet secondfeet ) during September . The mean flow for September , 1922 , was 7,000 , or nearly half as much as the flow during September , ( 1921 1-921 ) . The flow is also given for all of the Septembers in that same total , ( which -which which ) shows that the September flows during the various years have ranged from a mean of only 5,000 during 1928 , to 34,000 during 1927 . The average flow for September , ( , . ) based on these records , is 12,600 ( "second-feet secondfeet -secolid-feet secolidfeet ) . ( In Ili ) other words , a party going through the river in ( Septem- Septem ) |
