The cost of irrigating lawns by this method is 

 far less than by the use of circular sprinklers, for 

 both time and water are saved and the lawn is 

 supplied with a more even distribution of moisture. 



There is another plan of irrigation which is 

 known as the underground pipe or tile system. 

 This is not often used because the first cost is too 

 great. In some cases, however, it has proven to 

 be satisfactory. 



The part of any sprinkler system that deteri- 

 orates most rapidly is the rubber hose. When it 

 can be replaced by iron pipe it should always be 

 done to save expense. 



Where hose is used it is usually necessary to 

 purchase a new supply each season. Its first cost 

 is two or three times more than that of a galvan- 

 ized iron pipe and the pipe usually lasts from ten 

 to fifteen years. There are several other systems 

 of irrigation of lesser importance, but it is not 

 necessary to describe them here. 



THE MENACE OF WEEDS 



However well the soil may be prepared for 

 garden or lawn, and whatever the attention given, 

 the cultivated plants of every description are per- 

 petually menaced by the rivalry of weeds. 



A weed may be said to be a plant out of its 

 proper place so far as the economy of man is 

 concerned.
