Still another series of observations made by Doctor Morrill, at Austin, 

 Tex., shows that similar conditions prevailed in localities nearly 100 

 miles apart. For each of these percentages 300 squares were exam- 

 ined, thus making 14,400 observations in the series.

As the first records at Austin were made about ten days earlier 

 than were those at Calvert, they serve to show a much greater total 

 increase in the average infestation during August, though the average 

 daily increase in the percentage of infestation agrees very closely in 

 the two localities, being 1.8 per cent at Calvert and 1.9 per cent at 

 Austin. 



A decrease in square production accompanies the maturity of the 

 bulk of the crop, owing to the fact that the assimilative power of the
