ceased and most of the cotton plants were pulled up 

 previous to the date mentioned. Cultivators in Upper 

 Egypt still continued to cut their cotton after having 

 sown berseem (clover) in the standing crop, and volunteer 

 cotton was frequently found in the late spring in conse- 

 quence. Insufficient attention also was paid to the 

 destruction of bamiah and tehl. 



Nevertheless a beneficial effect was apparent in almost 

 every instance where a comparison was made between 

 the bolls attacked by Earias in 1912 and those from the 

 same localities in 1913 (see Appendix I). It is true that 

 in some cases more bolls were attacked by boll worms 

 than before, but upon examination it was found that the 

 depredator was not Earias, but the new pest, the pink 

 boll worm. 



In consequence of the rather sudden appearance of 

 the pink boll worm in Egypt, a proposition was made 

 early in May, 1913, by myself, in my capacity as Member- 

 Reporter of the Cotton Worm and Boll Worm Commis- 

 sion, to the said Commission that a clause might be 

 inserted in the existing Boll Worm Law No. 19 (1912) 

 to the effect that it should be made compulsory to detach 

 and destroy all bolls upon cotton plants immediately 

 after the last picking of cotton. This measure would be 

 equally efficacious for the destruction of hibernating 

 Earias boll worms as for the other species. 



The Commission having at its meeting of May 8 

 favourably entertained the above proposition, submitted 

 the same to the Government, with the recommendation 

 that the proposed necessary steps be taken for the eradi- 

 cation of the pests. 



In a subsequent letter, dated July 3, to the Govern- 

 ment the Commission expressed a wish that it be made 

 compulsory for cultivators to detach immediately after 

 the last picking all the bolls remaining on the cotton 

 plants before the removal of the plants ordered by Law 

 No. 19 (1912). 



Further, the Commission was of the opinion that the 

 destruction of the worms in the bolls detached in the 

 above way could be done by their submission to the heat 

 of ovens. This system would have the double advantage
