iug the wells located as we Lave described, must in time become saturated with organic 

 filth of a most objectionable character. Such soil is then no longer able to purify 

 the water passing through it, but rather serves to contaminate it more seriously. 



We strongly advocate the bored or drilled well, tapping a deep-seated source. It 

 cannot be stated that such a well will necessarily yield a good drinking water, but 

 nevertheless it is the source of supply to be generally recommended for the isolated 

 household. If there are no fissures in the overlying strata and there is no oppor- 

 tunity for water to flow downwards between the piping and the sides of the boring, a 

 good water will in all probability be obtained. 



To those, who for one reason or another, must rely on the shallow well, we would 

 Bay that the area around the well, say for a radius of at least 50 yards, be kept free 

 from mannre and all filth. It may preferably be kept in sod. Another precaution 

 of considerable value towards the protection of the well water from organic filth, 

 is toi line the well to a depth of say 10 to 12 feet and to a thickness of say 6 inches 

 with concrete or puddled clay. This lining should project some G to 12 inches above 

 the mopth of the well. This will prevent the direct inflow of wash and of water 

 from the surface soil and will in all probability ensure a certain amount of filtration 

 through clean layers of soil. 



During the year 168 samples were submitted to analysis. The analytical data 

 and a summarized report as to quality are given in the appended table. Sixty-two 

 were pronounced as pure and wholesome, forty-four as suspicious and probably 

 dangerous and twenty-five as very serioiisly contaminated. Thirty-four samples were 

 too saline for potable use. 



Farmers desiring an examination of their water supply are invited to send for 

 a copy of the directions to be followed in the collection and shipment, of the sample. 

 Saraplee are constantly being received at tb.e laboratories which, owing to insuffi- 

 ciency in quantity, dirty containers or corks, or through other causes cannot be sub- 

 mitted to analysis; trouble and expense to the farmer will, therefore, be saved if these 

 instructions are first obtained and faithfully r arried out.
