Professor Shaler. You know that about twenty years ago an 

 interesting Frenchman brought an interesting bug to this country. 

 His name was Trouvelot, and he brought the creature thinking to

 Legislature and begged for some money, advising them to put a hun- 

 dred thousand dollars at the disposition of a trustworthy commission. 

 They appropriated fifty thousand dollars and appointed a commission 

 which did a good deal of work and expended a good deal of money 

 and energy. I begged them to bend their energies to bringing in the 

 boundaries as far as possible, to pay the market price for eggs and 

 grubs, and to put their inspection work in progress ; but they went 

 into a miscellaneous sprinkling and burning over the whole terri-

 would take a line thirty miles long to enclose the area these insects 

 occupy. They are found in a territory of not far from fifty square 

 miles, though not all over it. I should think that not more than 

 ten square miles were solidly occupied. On the rest of it there

 great distance. Another encouraging fact is that, as far as I can 

 learn, save at two or three very limited points south of the Charles 

 River, the creature may be enclosed in this line on this side the
