This is distinctly evident in the planting of colonies at widely different 

 1 mints, so as to avoid their destruction or loss by any local condition, 

 ;ni(l the placing of colonies :il such distances from points under artificial 

 treatment that they will not be lost by various methods of artificial 

 destruction. I was specially impressed with the advantages in this 

 select inn. since it will serve a double purpose, that of controlling 

 the insect in places in which its artificial control is impossible, thereby 

 lessoning the power of overproduction and consequent migration, while 

 at the same time giving the greatest promise of permanent establish- 

 ment of parasites. I may say that, while my own hope with regard to 

 the value of the introduction of parasites for this purpose heretofore 

 lias been rather slight, the plan and methods adopted in your work 

 have given me much greater confidence in its value. It certainly is 

 deserving of the most careful and extended trial that can be given. 



While it was not specified as a part of my program, it was a matter 

 of much interest to me to note the methods adopted in the control for 

 these introduced pests; and I was very much impressed, in travelling 

 through infested districts over some hundreds of miles, over roads the 

 borders of which had all been cleaned and treated, with the extreme 

 care and the great efficiency that has been attained in this work. Evi- 

 dence is at hand at every point that a thorough study has been made, 

 and an application of every known method by which the successful 

 control of these insects may be reached. It was a matter of much 

 interest to me, also, to see the system of accounts in your office, which 

 has been so simplified and perfected that the expenditures in each dis- 

 trict and for every purpose may be learned with the least expenditure 

 of time and effort. This system must be a great satisfaction to the 

 authorities both of the State and of the townships interested, inasmuch 

 as it affords such complete information as to all classes of expenditures. 

 While this report might be much extended were I to include all of the 

 different features of your work which were of interest to me, it seems 

 to me that nothing can be gained by such a statement of facts as are 

 already familiar to those who have looked into your work and which 

 must be well known to the residents of the locality. 



To sum uj) in brief, therefore, I may say that the work of your 

 department appears to me to lie directed in a most intelligent manner 

 towai'd the accomplishment of its purpose; and that, in the efforts to 

 introduce parasitic enemies that will lie of service in the control of 

 these introduced pests, there is evident the utmost care and intelligent 

 study of all the conditions which will favor the success of the under- 

 taking. The success that it is hoped to attain in this direction, while 

 undoubtedly of most particular interest to the re-inn infested, is of 

 extreme infcre-i to the residents of the surrounding States; and it 



gives me exlre pleasure to find that the work of control is being so 



efficiently administered. 'Willi sin h work in progress there is certainly
