WHERE WATER GARDENS CAN BE MADE I5 



from a pipe with a^piget. It is not necessary 

 to maintain a continuous flow and change 

 of water. Just as a balanced aquarium will 

 go for weeks or months without attention, 

 so it is with the pond. It is only requisite tol 

 replace the water lost by evaporation and s, 

 leakage. I 



WATER LOSS BY EVAPORATION 



From a surface of sixteen square feet, about ; 

 a bucketful of water escapes every day by 

 evaporation and transpiration of the plants. 

 Stagnation is prevented by having a few , 

 fish and some submerged plants like Cabomba 

 or Myriophyllum. It is therefore very easy 

 to care for a garden up to six by twelve feet, 

 even with only a bucket to supply water. 

 On the other hand, a large pond fed by a 

 natural stream will often be in danger from 

 floods. Unless the stream be very small in l 

 proportion to the lake it will be necessary to 

 have means of diverting it into a culvert or 

 sluice on occasion.
