of it IS required. On time and thoroughness are 

 virtues. First application should be made about 

 the last of June, when potatoes are about one 

 foot high. Spraying should be discontinued 

 from September 1st to 15th, depending on the 

 season. 



"The results of spraying for 1906 to 1911 follow: 

 This is the net profit, not gain: 1906, $42.07; 1907, 

 $32.42; 1908, $48.80; 1909, $20.08; 1910, $24.00. 

 The total cost of thorough spraying ranges from 

 $8 to $15 per acre. 



"Inside measurements of potato crates are 

 12 X 14 X 15j inches. Outside 12| inches high, 

 14f inches wide, and 17 inches long. They nest 

 up and fit endwise a three-foot wagon box. They 

 contain 2,562 cubic inches, and hold sixty pounds 

 potatoes level full. Ends are |-inch pine or white- 

 wood boards, 12 inches wide, cut to length; sides 

 and bottoms are |-inch basswood. We have 500 

 crates. 



"For harvesting the crop the Hoover digger is 

 used, digging every other row, beginning on lower 

 side of field and digging in divisions of four rows. 

 Four rows of potatoes are picked into two rows of 

 crates. The truck wagon passes to farther end of 

 field, distributing the empty crates. The wagon 

 is loaded on return by driving between the two 

 rows of full crates. One or two men on each side 

 set on to the wagon the crates of potatoes without 

 stopping. The truck wagon platform is 6 x 19 

 feet and only 30 inches above the ground. It 

 holds sixty crates, one crate high. Often 100 to 

 110 bushels are drawn. In 1906, 1,501 bushels 

 were dug and picked up in one day and over 1,000 

 bushels drawn one mile and loaded on to cars. 

 Selling direct from field to car is highly satisfac-
