That Mr. Glover contemplated such a work before he came to Wash- 
ington is evident from a number of plates on stone 1 still in existence, 
made early in the decade from 1850 to I860, lie has more than once 
alluded to it in conversations with me, and but for the counter interest 
in pomology, and in the preparation of his models of fruit, he would 
have attempted it at that time. I take pleasure in reproducing here a 
plate made by him in February. 1852, which contains some ten species 
of insects, all of which are tolerably well drawn. (Fig. 5.) His work at

that period had attracted the attention of Dr. Harris, and some ten 
months after this plate was made he was in receipt of a letter from the 
doctor acknowledging his superior skill in the delineation of insect 
forms, and asking his cooperation in the preparation of a new work on 
entomology. I give herewith the main portion of Dr. Harris's letter, 
only omitting a page or more of explanation of figures in the plates 
Mr. Glover had sent him. It is as follows: 
Cambridge, Ma-.. Decemberlb, L852. 
Dear Sir: Your letter of the 7th instant with the specimens <>f your engraving and 
the drawing of i lie pear-1 ree Insects, reached me this day, and J am very much grati-
