SANITARY DRAINAGE OP WASHINGTON. 23 



I am sure some will agree with me that the special means proposed 

 will effect these desirable ends not only more economically, but 

 also more cheaply than it could be done by other plans that have 

 been suggested. A constant free outlet for the natural land drain- 

 age several feet below the surface of the drained flats is in itself a 

 most important object.
