DUTY AT HEADS OF LATERALS. 
During the investigation, records of discharge and acreage irri- 
gated were obtained for a number of laterals to afford a comparison 
of the duty measured at the head of the lateral with the duty meas- 
ured at the head of the canal. The results of the measurements, to- 
gether with the comparisons, are shown in Table 14. These erratic 
variations may be occasioned by a number of conditions. There are 
no restrictions on holdings of shares of ditch stock with reference to 
the acreage irrigated, and under a single lateral the ratio between 
the two may be as much as 20 per cent above or below the average 
ratio for the entire canal. Such a lateral would be entitled on its 
shares to an amount of water 20 per cent above the average for the 
entire canal. What is true of canal shares is true to a greater degree 
of reservoir rights carried in the canals which act as common carriers, 
for water from this source is limited only by the number of rights 
Tvhich can not be bought, rented, or borrowed. A considerable part 
of the variation may be attributed to systems of distribution to 
laterals. A few of the canals, including the Little Cache la Poudre 
and the Jackson ditches, have no measuring devices for distribution
