The number of seeds that failed to vegetate is very noticeable. 
In 125, the sparrows removed some kernels from the heads and also 
there were some kernels which did not fertilize.

For the purposes of this presentation we have the records of the 
same plats for three years, and the figures which are to be given are 
as below for each half plat of one-twentieth of an acre, in sod in 
1881. The yields in ear corn: ; 
1882. 1883. 1884, Total, 3 years.

In series . A Waushakum corn was used, in series II. A, a yel- 
low flint corn without name in 1882, and Waushakum in 1883 and 
1884. In series II. A lower, in 1883 the plats were root-pruned 
to the injury of the plants. We must therefore observe that the 
conditions are not precise duplicates between the two series, yet are 
such as to admit of averaging the results, which we proceed to do, 
as follows :

The average yield on the face of the figures is therefore 52.8 
bushels per acre, the greatest variation from this average 4.1 
bushels, or seven per cent. 
We have now given the actual figures as obtained, but these fig- 
ures are really not comparable for this purpose until we have cor- 
»cted them through allowance for missing hills. By planting six -
