As the variation between the extremes of these figures are no 
greater than occurred in our designed duplicates D 18 and E 17, as 
heretofore discussed, these series may be considered as duplicates 
and we note that the mulched plats were superior in crop two out of 
the three times, but the average yield of the mulched was 445.5 lbs. 
of the unmulched 464.4 lbs., or as near a duplicate yield as could be 
expected, the figures, however, slightly against the mulching. 
In D and E series we have duplicates again. The yield in order

We have in this series the mulched plats the better both trials, as 
also better results upon the average, there being an average yield of 
807.9 pounds merchantable from the mulched plats, and 686.6 pounds 
merchantable from the unmulched. Yet the difference is no greater 
than between designed duplicates, and hence cannot be considered 
as decisive. 
As all the seed did not furnish plants we append a corrected table, 
caleulated to an even plant of 594 hills per plat, whereby it will be 
seen that the correction does not change our conclusions
