The coarse holes or punctures above described, which are seen in the bark, are by no 

 means made by the puncture of the insect. He has no occasion for any such chasms; but 

 they are the result of the sloughing off of the poison he leaves wherever he goes, as you 

 will soon see by cutting into one of them. 



In conclusion, I would say that I have been advised by my friends to withhold the pub- 

 lication of these facts till I could take time to trace out thoroughly the history, changes, 

 and remedies, for this (\ital insect, whatever its name may be; though were I to christen 

 it, I should call it the " Pear Devil.'" 



I read the article of Mr. Allen, on pears, in your last number, with great interest, 

 and I reflected that there was millions of dollars worth, of valuable property, now in the 

 process of destruction in the United States, as well as my own; and at the hazard of great 

 mistakes, errors, and even of ridicule and contempt, in the present crude state of the in- 

 quiry, I have felt it m^' duty to testify as above, to what I have seen, and to turn all other 

 eyes, at once, and without delay, to this larvae, while it may yet be seen, thinking that this 

 course gave promise of more safety, and of a more extensive, prompt, and thorough in- 

 vestigation, than any one man, (especially one so busy as I am in other matters,) could 

 possibl}^ make alone. And at all risk of errors, I shall not hesitate to report progress 

 from time time, for we need the million eyes here, instead of one pair; and if others find 

 out and describe more accurately than I can now do, the nature and habits of this pest, 

 (as they surely will,) no one will rejoice more than myself — while I cannot but think that 

 the public will respect my motive for publishing without delay, even after the^' have from 

 a more thorough knowledge, corrected the errors which almost of necessity must lie latent 

 in an}' statement made at this point of our research. 



Allow me also to saj', that since I have been engaged in these inquiries, I have most 

 deepl}' felt the need of such an Industrial University,* endowed by Congress lands in 

 each of the states of the Union, as is recommended in the report of the Granville Conven- 

 tion, a copy of which I sent j'ou. They could be erected, and the nation would never 

 feel it; while it would in a few years double the intelligence, wealth, power, and glorj' of 

 each state, and the Union at large. 



Our state, and I hope several others, will move soon. Can you not say a good word for 

 us.'' Your own Governor Huxt takes the right view of this matter, I am happy to per- 

 ceive, as well as many other eminent men among your citizens. 



I hope, and barely hope, that either some of the many remedies I have applied, or bet- 

 ter, some change or peculiarity in the season, may check the career of this minute but pes- 

 tilent destro3'er, and save my trees yet a little longer; and when the scourge is once past, 

 it probably may not return again for years to come. I notice, also, that trees once severe- 

 ly affected, last season, have not so many, if any eggs on them this year, which incites 

 a hope that the same tree may not be visited but once in the course of its histor}"-, with a 

 course of the disease, and that those which escape with life will stand triumphant, as the 

 trees of olden time may have done before them. 



I am suspicious, after all, that this is the same identical disease attributed to fungus by 

 Mr. Knight, and others, for its phenomena are much the same; and I myself, settled 

 down in the conclusion that this little flocculi on the bark, (the evident cause of the dis- 

 ease,) was a fungus, until I chanced to hear an egg crack under m}' knife, and examined 

 with the microscope, and found it as above stated. 



I shall call a witness or two if I can, to the facts stated above, as I desire that 



* AVliich we shall noiice in our next. Ed.
