this fact is sufficient in itself to make it particularly useful 

 tp agriculturists, as well as to others by whom it will 

 doubtless be consulted, who do not possess the time or the 

 facilities for reference to entomological subjects that are of 

 importance to them. My thanks are due to Mr. Ballou, 

 for the careful way in which the work has been compiled, 

 and it is due to him, also, to place the fact on record that 

 the book derives an additional value, which will be recog- 

 nized to an increasing extent as it comes into general use, 

 from the circumstance that it presents information that is 

 the outcome of his special work and observation in the 

 West Indies information that in many cases relates to 

 forms of insect life, both injurious and beneficial, that were 

 not known previously to be of economic importance.
