square rod in area, as they were the year before, and separated from 
each other by strips of oats 1 yard wide. Two plats of each variety 
were planted side byside. (See fig.39.) Plate X shows a part of the 
experimental plats used this season. The moths were not quite so 
destructive this season as last, 2.5 per cent being the greatest damage

Table III gives the data of this season’s work and is self-explan-

done to all plats which came into full bloom on any one date. Figure 
. 40 graphically illustrates these results and very clearly shows that 
varieties which were in full bloom prior to June 28 were practically 
unmolested.
