6-year period. For that reason averages are given for two 4-year 

 periods, a 5-year period, and the 6-year period. In the first four 

 years, from 1914 to 1917, inclusive, the highest average was made 

 by the 15 to 18 inch spacing and the lowest by the 9 to 10 inch 

 spacing. In the four years from 1915 to 1919, omitting 1918, the

20 to 24 inch spacing ranks first, while the 6 to 8 inch spacing is 

 lowest in yield. In the 5-year period from 1914 to 1918, inclusive, 

 which includes only three rates for all years, the averages are approxi- 

 mately the same. In the 6-year period the averages are approxi- 

 mately the same for the two rates which are represented in all years.
