IRRIGATION ROUND TABLE 119 



Mr. Rogers: Yes. 



Mr. Work: Twenty-eight feet of elevation is the limit for suc- 

 tion. Does he ever move pipe lines 



Mr. Rogers: Yes, last fall we had a lot of lettuce so dry that 

 we put a few temporary lines in on trestles or on the ground. We 

 watered five acres with two lines by moving. 



Mr. Work: The question comes up, which is cheaper, to move 

 the lines or increase the investment? Mr. Wrigley, have you tried 

 moving? 



Mr. Wrigley: Yes. It is necessary to use a number of men 

 and be very careful. 



Mr. Work: Do you lose a good deal of time? 



Mr. Wrigley : We only move it once a day. 



Mr. Work: Would your policy be to put it in permanently? 



Mr. Wrigley: Yes. 



Mr. Work: Mr. Talmage, are you familiar w^ith the Hallock 

 farm? 



Mr. Talmage: I have been there. Mr. Hallock is located to 

 very good advantage for market garden business. His farm is natur- 

 ally very low, and he owns a steamer with which he brings large 

 quantities of manure from New York. He started two or three 

 years ago to use the Skinner system, and has increased up to sixty 

 acres. He is a very conservative man, and when I asked him for 

 results, he said he wasn't prepared to say. He said in his case he 

 had found it more valuable for starting the second crop than for 

 producing the first. Someone asked Mr. Hallock if he would advise 

 his neighbors to go into it, and he said no, to use more horse manure. 

 The idea was to save the moisture with the humus rather than to 

 put in a system which means an enormous expense. Where you 

 carry waiter in large quantities, you have got to have a very big main. 



Mr. Work: Where does he get his water? 



Mr. Talmage: He has dug a well not more than eight or ten 

 feet above the level of the sea.
