elms iu Washington. Ami please, if yon send any. at the same time semi the scien- 
tific names, as I can then identity them by referring t<> English works. By the way, 
what are your best agricultural entomological works, as 1 shall order them here f I 
have Morton's Encyclopaedia of Agriculture, West wood, and sundry other English 
works; have ordered Eat/hurl's Foist Insecten, etc., so that I shall also be able to 
compare with the German. Dr. Girard, who is at present in Germany, lias promised 
to send me all the German insects he can procure. If you know of any one who has 
ahout £5 worth of common (no rare) insects to sell, please let me know. I want those 
principally that injure crops, and of all orders. As soon as my plates an- finished I 
shall send you a copy, as likewise of the cotton aud orange insects I finished whilst 
in the service of the Patent Office. 
Mr. (Hover was now in his forty-seventh year. Of his work daring 
the last six months of 1859 there is little to record, save that he applied 
himself most industriously to his undertaking. After becotniug eun- 
nected with the Maryland Agricultural College, about I860,* he found 
himself in better position to push his work. Living in the country, there 
were more opportunities for observation and for the study of" the habits 
of insects. Then he was accompanied iu his field rambles by his stu- 
dents: and with their aid, and the material contributed from his breed- 
ing cages, he soon accumulated a fair collection of the principal insect 
forms of the locality. Always ready with his pencil and colors, he fig- 
ured everything he saw that was thought to be new, even making draw- 
ings of caterpillars and chrysalids of species that he was unable to rear 
to the perfect state, and which in many instances he was not able to 
identify until years after. Some have never been identified. This par- 
tially accounts for the incongruous arrangement of the insects on the 
later plates, as relating to classification, in comparison with the earlier 
ones, where family grouping of well-known forms is the rule. 
It is to be regretted that Mr. Glover did not regard his insect collec- 
tion of more value, and had not shown more care in the preparation 
and after-preservation of the specimens. After figuring an insect the 
specimen had little further interest for him. Indeed he did not take the 
trouble to set some of them at all, or only iu such manner as would ad- 
mit of their being correctly drawn. He used for the purpose entomolo- 
gical pins, the ordinary pins of the dressing-case, or even needles : the 
specimens were set at various heights, and were sometimes badly dam- 
aged in the mounting. Many of the Lepidoptera, as well as other forms 
with large wings, were most carelessly prepared, these appendages 
drooping or stickiug out in several directions. When I first saw his 
cases, in 1866, the ravages of mold, verdigris, and anthrenus appeared 
in almost every box ; single wings, antenna . and legs were often want 
ing, and now and then a body. Nor could it have been otherwise, for 
the boxes, made to open like books, were mostly without cork, the tough 
pine wood at the bottom making it difficult to secure a specimen, the 
pins being frequently bent or broken at the points and sometimes turned 
at a right angle. Had his collection been better preserved and his types 
"lean not learn the exact date of .Mr. Glover's connection with the Maryland 
Agricultural College. It must have been the latter part of 1859.
