PROSPECTS. 



The rapid spread of the boll weevil in the past few years and its 

 apparent adaptability to most of the conditions prevalent in the 

 cotton region of t\w United States indicate that it will ultimately be 

 able to exist in all except the semiarid portions of the entire eotton- 

 growing country. In order better to estimate the probable move- 

 ment in the future, we present Table V to illustrate 4 its progress since 

 the year 1892:
