816 CONGRESSIONAL PROCEEDINGS. 



The manner in which Mr. T. Glover is carrying out his plan is in every way satis- 

 factory and deserves the highest commendation. By way of a certain combination 

 of labels or marks the useful and noxious are easily distinguished. The fruits repre- 

 sented by casts made by Mr. Glover himself, in an unsurpassed manner the different 

 kinds of seeds, their products, etc., give to everybody clear indications of which kind 

 of culture is best adapted for any State or even for a part of earth. 



The insects, noxious and useful, with their products, are largely exhibited, and 

 form in this manner an unrivaled museum. Mr. Glover has adopted for them a plan, 

 so far as I know, only comparable in a certain sense to the excellent catalogues in the 

 Hunterian Museum in the College of Surgeons in London. Mr. Glover has figured 

 all the insects, as most of them are too small otherwise to be recognized by the naked 

 eye or to be understood by visitors not initiated in the technicalities of the science. 



If necessary, figures of the transformation or product are added. 



These figures, mostly very superior to any thus far published, are engraved by him- 

 self, and as the catalogues of the Hunterian Museum form for the visitors and stu- 

 dents a sure and excellent guide to the drawers in which the specimens are exhibited. 



I confess I have no idea how one man had the power alone to accomplish so much 

 work in such a superior manner. I have seen in the papers it would perhaps be 

 possible to have the extensive entomological works of Mr. Glover published. With- 

 out any doubt such a publication would not only be of the greatest use for Ameri- 

 can students, but even accepted by the whole scientific world with the greatest satis- 

 faction. 



Respectfully, yours,

COALBURG, W. VA., December 28, 1878. 



DEAR SIR: I am very glad to hear that an effort is making to secure for the coun- 

 try Professor Glover's copperplates of the insects of the United States, and his manu- 

 script relating thereto. These materials are invaluable to us, and should Professor 

 Glover dispose of them in England or elsewhere the loss could never be made good. 

 Being an enthusiastic entomologist, as well as artist, these plates have been to him a 

 labor of love, and he has given to them the better part of a lifetime and executes 

 them with the greatest fidelity. His work on the cotton insects is beyond all praise. 

 I know of nothing comparable to it on the range of entomological illustrated litera- 

 ture, and the plates of this work and notes belonging to them are worth, in my opin- 

 ion, to the country the full sum that Professor Glover requires for the entire lot of 

 plates and manuscript. This work ought to be circulated broadcast over the cotton 

 States for the instruction of the planters and growers. So the insects that infest the 

 sugar cane, the orange trees, the grains, roots, etc., and the several forest trees are 

 nearly all, so far as they are known, figured on these plates. It is of very little use 

 attempting to convey knowledge of the insects injurious to agriculture to the people 

 at large unless colored figures of the insects accompany the text. Such figures 

 appeal to the understanding and memory, and for instruction are absolutely neces- 

 sary. The loss to the nation by the ravages of insects is annually hundreds of millions 

 of dollars, and the agriculturists everywhere need to be instructed as to the appear- 

 ance of their enemies before they can intelligently comprehend advice as to over- 

 coming or counteracting them. By all means let us have those plates of Professor 

 Glover as the first step in proper education on this subject. 

 Yours, truly, 



W. H. EDWARDS.
