the progress of the work. Success seems an ultimate certainty, but the 

 time at which perfectly obvious results will be apparent is as yet un- 

 certain. By perfectly obvious results I mean a marked diminution in 

 the numbers of gypsy moth and brown-tail moth over a region of some 

 extent, which by expert examination can be shown to have been brought 

 about through the work of introduced parasites. 



SUMMARY OF RECOMMENDATIONS. 



Recommendations are : - 



1. To continue the field work at its maximum efficiency, 

 an appropriation of $150,000, in addition to that already pro- 

 vided for the year 1909, should be made. 



2. To continue the work of importation of parasites and for 

 work on fungous and bacterial diseases, an appropriation of 

 $15,000, in addition to any unexpended balance, should be made. 



3. To provide for the uninterrupted continuation of the 

 work against the gypsy and brown-tail moths, that the work 

 may not suffer from legislative delays in the winter and spring, 

 when most effective work can be done, a suitable appropria- 

 tion should be made for a period of at least three years.
