then in good roasting ears. The results are given in Table II.

On the same date a field of crop corn just tasseling was similarly 
studied. Tlie number of plants examined is not given, but simply those 
upon which worms were found. The larvae in nearly every case were 
found in the freshly protruded or protruding tassel. The facts are pre- 
sented in Table III.

Much error prevails among planters as to the causes of the shedding 
of the cotton crop, and that much of the blame has been misplaced is 
shown by the following tables. The data upon natural shedding (Table 
IV) and the natural or normal average number of bolls matured by a 
cotton plant under favorable conditions (Table V) were noted in fields 
entirely free from Boll Worm ravages.
