elms in Washington. And please, if yon send any, at the same time send the scien- 
tific names, as I can then identify them by referring to English works. By the way, 
what are your best agricultural entomological works, as I shall order them here ? I 
have Morton’s Encyclopaedia of Agriculture, Westwood, and sundry other English 
works; have ordered Ratzburg’s Forst Insecten, etc., so that I shall also be able to 
compare with the German. Dr. Girard, who is at present in Germany, has promised 
to send me all the German insects he can procure. If you know of any one who has 
about £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 are finished I 
shall send you a copy, as likewise of the cotton and orange insects I finished whilst 
in the service of the Patent Office. 
Mr. Glover was now in his forty-seventh year. Of his work during 
the last six months of 1859 there is little to record, save that he applied 
himself most industriously to his undertaking. After becoming con- 
nected with the Maryland Agricultural College, about I860,* he found 
himself in better position to push his work. Living in the couutry, there 
were more opportunities for observation and for the study of the habits 
of insects. Then he was accompanied in 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 in 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 sticking 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 
* I can not learn the exact date of Mr. Glover’s connection with the Marylaud 
Agricultural College. It must have been the latter part of 1859.
