Mr. Glover did not take up with this offer, as he doubtless had otluT 

 plaus in view for himself; but the letter is interesting, as funiishiug 

 evidence that Mr. Glover not only worked upon copper at that early 

 date, but also upon stone. I have in my possession proofs of a number 

 of these plates engraved upon stoue, the execution of which is far bet- 

 ter than the work on his copper plates of the same period. Of one of 

 these, illustrating parsnip insects, Dr. Harris says : 



No. 1 is apparently one of tlie Ortalidae ; its larva unknown to me before No. 2, I 

 have often seen the larva of this moth, but never succeeded in obtaining the perfect 

 moth. 



So Mr. Glover was a good observer, as well as a tolerably skillful 

 engraver at this time. 



Mr. Glover's reply to Dr. Harris's letter would be interesting could 

 it be produced. I have searched for it among the Harris correspond- 

 ence at the IvTatural History Society rooms in Boston, but without avail. 

 The letter was very flattering to Glover, as he has himself told me; but 

 he was not then ready to enter into such an arrangement. What other 

 correspondence may have passed between them at that time can not be 

 stated, but a little over two years after Mr. Harris wrote another letter, 

 which not only gives some interesting facts in Harris's life hitherto un- 

 published, but is certainly most complimentary to Glover. This is the 

 letter : 



Cambridge, Mass., February 13, 1855. 



Dear Sir : On the 4th of Septeisber I received a letter from D. J. Browne, esq., 

 then at New York, and on the point of sailing for Europe, informing me that you had 

 been engaged in making drawings of insects to illustrate the next agricultural re- 

 port of the Commissioner of Patents, and wished to pre-engage my co-operation Avith 

 you. He farther informed me that you were then absent from Washington, some- 

 where in Georgia or Sonth Carolina, and that on your return in November yon would 

 visit me in Cambridge. He also stated that he would communicate with me again 

 on the subject on his return from Euroj)e. Under these circumstances there seemed 

 nothing for me to do but to wait till I saw you or till I heard from him. Moreover, 

 my oldest son was dangerously sick and remained so till his decease on the 19th of 

 October, and in our trouble Mr. Browne's communication was entirely forgotten till 

 it was brought to my mind by a letter received from Hon. C. Mason on the gOth of 

 November. To this letter I replied on the 8th of December, since which time nothing 

 has been heard of the subject therein proposed. I hope that you have seen my answer 

 to Mr. Mason ; if yon have not, let me beg you to request him to show it to yon. I 

 shall be happy to render you any service that is in my power consistent with my 

 other duties and engagements. These will fully occupy me from the 1st of March 

 till the middle of July ; so that you must not count on me for any assistance from me 

 during that time. At this present time, having a vacation in college, I am more at 

 leisure than usual. I regret not to have received the expected visit before the open- 

 ing of the college session. 



Indeed, I have been long expecting a visit from you as jiromised some two years 

 ago, in which I hoped to have made some arrangements with you for illustrating my 

 work on insects. The time is .-ome in which 1 have an expectation of being able to 

 defray the expense of illustrations to the work, and in which it will become neces- 

 sary for me to take some decided measure for having them done, if they are to be 

 done at all. The committee on agriculture of the legislature of Massachusetts are 

 now considering the expediency of printing another (the third) edition of my work>
