unites also of the percentage which would be used each month, if 
the irrigators under the present crop conditions could have the water 
whenever they wished. 
Similar statements and estimates were obtained from several of the 
officials of the larger ditches mid from such consumers as could be 
reached. With these statements, and a knowledge of the average 
How for each month, the conclusions were as shown on the diagram. 
The opinions unci figures were remarkably uniform in general state 
ment, the greatest difference of opinion being as to the relative use of 
water for July and for August. Those contending thai the use was 
greater in August were under a ditch with good reservoirs, while 
those who believed it was the greater in July were irrigating with water 
direct from the river. The commissioners were inclined to believe 
the use in July was the greater, and, considering the flow in the stream, 
such appears to he the case. The figures on which the diagram is based 
are e/iven in the following table:

The first column is simply the recorded flow of the stream; the 
second is an average of the amount of water used directly on the land, 
and is the result of a comparison of the reports of the superintendent 
and of the commissioners of irrigation who have direct control of the 
water distribution. The ilow of the stream as recorded, and the fact 
that much of the loss is during extensive Hoods, though this loss is 
generally for a very short period, have been considered in making the 
table. The conclusions given in the third column are taken from fig- 
ures furnished Irv the superintendents and commissioners, and it is 
probably the most nearly correct column in the table. After June and 
until October there is a greater demand than the average flow of the 
stream, and yet during June and July water is stored. The demand
