We noted that the solids in solution and the chlorine were 

 lowest to the west and north of the city, while to the south and 

 east they are much higher and in the deeper wells are very high. 



The normal chlorine maps of Massachusetts and Connecticut 

 are so helpful in those states, giving a standard for comparison, 

 that we would like one here. The analyses of these country 

 wells from all sides of Lawrence, together with the city wells, 

 show that such a map of this district would be difficult to make, 

 and, if made, valueless, for chlorine alone cannot be used as a 

 test for contamination.
