large yield from the two eye pieces is one of those erratic conditions that 

 often result in experiments of this kind. It shows the need of many experi- 

 ments under varying conditions in order to establish a scientific truth. 



We find the variation from our other results even more strongly empha- 

 sized in the table of relative profits. Here the two eyes are most profit- 

 able, with the half second, the one eye third and the whole least of all.

drills. The hills were 33 inches apart each way, the pieces being 16^ 



inches apart in the drill row. 



Size of the plat, 4x16 rods.
