ill chiiryc' of the, head o'atos was thou iiistnu-tcd to hold the water at 

 the same hri<;lit chiriiiu' tlie sul)S('(|iu'iit lucasurcuuMits. The tichl pai'ty 

 then travi'k'd down the canal, inoa.suriiio- each di\('isioii and each 

 iiitlow as tlit'V passed it. At some suital)le point on the canal, prefer- 

 at>ly at a road crossint,^, the canal was ineasured a second time. Tiie 

 diti'erence hetween those measureinents, provided there wore neither 

 di\ersions nor intiows, re])resonted the losses in transit l)etween the 

 points of measurement. In case there were diversions through later- 

 als and intiows from creeks or other sources the canal was debited or 

 credited, as the case mij^ht he, w'ith the respective amounts. All 

 uieasurements of main canals were made w^ith current uiotoi's in the 

 customary wa}^ but the methods used in the measurement of laterals 

 depended somewhat on the accuracy of the measurincr devices beloni^ing 

 to each canal. As a rule all lateral diversions were measui'od over 

 weirs or with current meters. 



The results of all such mi^isuremonts made are sunuiiarized in the
