It will be noticed that the alkali has increased over 
fourteen times, and the presence of phosphoric acid would 
be another proof of seepage. It will also be noticed that 
the total solids have increased over ten times. In this case 
the seepage water was largely diluted with the river water. 
A sample of seepage water was taken from the garden of the 
College farm, 50 feet from the Town Ditch. Found 240.4 
grains of solid matter to the gallon:

It will be noticed that there is quite an agreement be¬ 
tween the river water and the seepage water in the pro¬ 
portion of sulphuric acid, carbonic acid and alkalies pres¬ 
ent, the seepage water having about four times as much 
solid matter to the gallon. 
The condition of the well water was examined with 
reference to alkali. A well was selected five miles from the 
foothills, away from surface drainage ; it was fourteen feet 
deep, and when the sample was analyzed (April, 1889) had
