The plot had an area of a little more than an acre. The land 

 had been in grass for several years and for the preceding two 

 seasons had been used as a run for growing chickens. The soil 

 is a rather heavy, fairly uniform loam, with a clay subsoil. It 

 was plowed about seven inches deep in the fall of 1902, and was 

 worked several times in the spring of 1903 with the Clark 

 double action cutaway harrow. Because of the unusual dry- 

 ness of April and May the turf was not as well rotted and broken 

 up as usual or desirable. The top however was thoroughly 

 pulverized and would in ordinary seasons have proven a good 

 seed bed. The seed was soaked in formaline solution for scab 

 before cutting. About a bushel of each variety were used for 

 seed. The piece was planted about May 12, 1903, six inches 

 deep, with a Robbins potato planter in rows 32 inches apart and 

 12 inches in the row. A fertilizer carrying 3 per cent 

 nitrogen, 7 per cent available phosphoric acid and 4 per cent 

 potash was applied in the drill at the time of planting, at the rate 

 of 1,000 pounds to the acre. The stand was imperfect but dif- 

 fered greatly with the different varieties, ranging from almost 

 no stand with the New Queen to 2-3 stand with the Irish Cobbler 

 and the Green Mountain. The stand w^ith the different varieties 

 as measured by the number of feet to obtain 55 plants (hills) at 

 time of digging was as follows : —
