Lawn and Park Irrigation 393 



is so commonly the practice. The truth of this 

 statement will be readily appreciated when it is 

 observed that in order to saturate good lawns suffi- 

 ciently to force any water down where it will become 

 available to the roots of trees and shrubbery, the 

 ground must receive not less than 2 to 3 inches in 

 depth of water. But to apply this amount with 

 spraying nozzles is impracticable. 



If public parks and cemeteries were more gen- 

 erally laid out with a view to thorough irrigation 

 as a part of their proper care all through the cen- 

 tral and eastern United States, not only would the 

 growth of shrubbery and trees be far more luxuriant 

 and satisfactory, but dry seasons would not destroy 

 the many beautiful trees which so often succumb to 

 drought just in their prime. 



Wherever a good well can be had with abundance 

 of water and a lift not to exceed 50 feet, a lawn of 

 half an acre, with its shrubbery, together with a 

 vegetable garden or fruit orchard of several acres, 

 may easily be irrigated with a plant not costing 

 more than $300 to $500. Such a plant is repre- 

 sented in Figs. 121 and 122. This, including well- 

 house, 2% horse -power gasoline engine and double- 

 acting pump, having a capacity of 80 gallons per 

 minute, with over 1,000 feet of 2 -inch distributing 

 pipe and hose, cost, when put in place ready for 

 work, $440.

 lawn and garden, as represented at B, C and D,
