A GARDEN IN VENICE 



pump is disconnected, the small tube is drawn 

 up, unscrewed length by length, and the driving 

 of the main tube process is continued 



Good water at last reached, the ordinary pump 

 is again put to work, and for a day or two more 

 is kept continually going to draw up the sweet 

 water from outside through the holes in the 

 bottom tube, and so to entice and show the way, 

 as it were, to the spring below. 



Naturally this comes charged with sand, and 

 the sucking process is carried on until some 

 cubic metres of solid stuff are brought to surface, 

 leaving a hollow chamber or reservoir below of 

 corresponding size. In this the water collects, 

 and the flow, at first dribbling and spasmodic, 

 becomes regular and full.
