elms iu Wasliingtou. Aud please, if you 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 entouiological works, as I shall order them here ? I 

 have Morton's Encyclopajdia of Agriculture, Westwood, and sundry other English 

 works; have ordered Eatzburg'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 {tio 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 bis forty-seventh year. Of Lis work during 

 the hist six mouths 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 iu better position to push his work. Living in the country, there 

 were more opportunities for observation and for tbe 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 a[)peared 

 in almost every box ; single wings, antennii:', nnd lejis were often want 

 mg, 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 

 l)iue 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 Maryland 

 Agricultural College. It must have been the latter part of 1H59.
