§ 72. These analyses present the highest limit of the sul¬ 
fates not only for this month but for the whole time that the plot 
was under observation. The sample from well C, taken July 5, 
1897, six days after irrigation, shows the presence of 50.29 per cent, 
sulfuric acid, S0 3 , which is nearly 1.5 per cent, higher than the 
next highest one given and is the highest, with one exception, in the 
whole series representing the three seasons’ work. That the aver¬ 
age percentage of sulfuric acid for all of the analyses made of these 
well waters is lower than that shown by these for the month of 
July may be inferred from the fact that there are only 8 in the 105 
analyses made showing 48 per cent, or more of this constituent. 
§ 73. The analyses given show almost as great a range in the 
quantity of chlorids present as the whole number of samples taken. 
There are only a few exceptional samples which show either higher 
or lower figures for the chlorids than those given.
