EFFECT OF PRESENT STOBAGE ON FLOW. 19Y Plate X shows a ^mass diagram for the period embraced by theMiUinocket records (1901-1909) made up from the foregoing tableby plotting the values given in column 5 as ordinates and the timein months as abscissas. Plate X was engraved before the data for1910 in the foregoing table were available. The features of this dia-gram of especial importance are as follows: 1. For the interval of time between any two dates represented onthe axis of abscissas, the surplus or deficiency is obtained by sub-tracting the ordinate corresponding to the earlier date from the ordi-nate corresponding to the later date; if this difference is positive itrepresents a surplus; if it is negative it represents a deficiency. Anascending part of the curve, therefore, shows a period during whichthe quantity of available water is increasing, and
