Mr. Glover did not take up with this offer, as he doubtless had other 
plans in view for himself; but the letter is interesting, as furnishing 
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 stone, 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 the Ortalidse ; its larva unknown to me before No. 2, I 
have often seen the larva of this moth, hut 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 Natural 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 September 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 with 
you. He farther informed me that you were then absent from Washington, some- 
where in Georgia or South Carolina, and that on your return in November you would 
visit me in Cambridge. He also stated that he would communicate with me again 
on the subject on his return from Europe. 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 Double Mr. Browne’s communication was entirely forgotten till 
it was brought to my mind by a letter received from Hon. C. Mason on the 29th 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 you have not, let me beg you to request him to show it to you. 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 promised, 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*
