All leaves and debris were first swept off the beds, the latter were then 
dug and the seed just buried in the surface soil on June 18th, 1915.

Very little weed growth established itself on the open plots during the 
first rains, and very little weeding was done. By July 1916, however, 
the weed growth had increased, and it was then markedly heavier in the 
larger clearings, Plots XVIII and XX, than in the smaller clearings, Plots 
XVII and XIX. As an illustration of the relative weed growth in Plots 
XIX and XX, see Plate V. Beginning with July 1916, therefore, in order 
to test the effect of weeding, one half of each bed in Plots XIX and
