 area of about one square mile, being mixed with the native blue 

 form. Prof. Hine spent the greater part of the summer at the 

 Gulf Biologic Station in the interest of the Crop Pest Commis-

 of the Mississippi River. Prof. Ball reported that the Codling 

 Moth and the Grasshopper cause a million dollars worth of dam-

 thousand dollars last year, while this year it caused practically 

 no damage at all. Prof. Griggs reported on the fruiting habits
