FORTY-FIFTH CONGRESS, 1877-1879. 813 



account of its practical utility, but because during all the years of its 

 preparation it has been progressively identified with the Government 

 in the protection it has extended to the agricultural interests of the 

 country and is, to a very large extent, familiar to the agricultural 

 people; but, in his pecuniary circumstances, it would be unjust to 

 himself nay, impossible to donate in full what has been produced at 

 so great a sacrifice of time, labor, money, and health. He therefore 

 respectfully proposes a compromise that will doubtless be recognized 

 as liberal on his part and satisfactory to all concerned. 



The intrinsic value of the copperplates, including their purchase, 

 preparation, and the work of engraving them, is, at the lowest esti- 

 mate, $100 each, and this would be the charge of an engraver for the 

 plates and mechanical labor after having the insects figured for his 

 use. Your memorialist asks no compensation for the manuscript vol- 

 umes; these he proposes to donate entire; but he respectfully suggests 

 that it would be just to give him an equivalent to what would be 

 exacted by any skilled engraver at the rates which govern for such 

 work and which the Government would have to pay for the illustra- 

 tions requisite for a work of this kind: Therefore, 



Your memorialist prays that your honorable bodies appropriate the 

 sum of $27,900, to be paid to him on his delivery to the Commissioner 

 of Agriculture all his manuscript volumes on entomology and two 

 hundred and seventy-nine engraved copperplates illustrating the same. 



And he will ever pray.

ACCOMPANYING LETTER. 



To the Senate and House of Representatives: 



The undersigned begs leave to accompany his memorial to your honorable bodies 

 with some explanations and suggestions that may more properly and explicitly be 

 presented in a communication of this kind than in a memorial. 



A protracted experience in his profession has demonstrated that his work has been 

 greatly appreciated by students in agricultural colleges, by the farming people of all 

 sections of the country, and by all who are interested in this branch of natural science, 

 as its accurate and correctly colored figures, drawn from the insects themselves, 

 enable any person of ordinary education and capacity to identify the principal inju- 

 rious species known to affect our agriculture, as well as the beneficial species which 

 prey upon them. 



In many cases the species are so marked that persons having little or no knowl- 

 edge of entomology as a science are enabled to recognize the name of a given 

 insect, and, by referring to the text of the work, to trace its larval or other stages, 

 the food plants upon which it thrives, the time the eggs are deposited, the length of 

 time consumed by the insect in going through its changes, and lastly, the means by 

 which they may be destroyed. As the habits of insects do not change with their 

 nomenclature, and as their forms remain the same, the work must always be found 

 invaluable for reference and identification. In the few instances in which names 

 have been changed during the past two years the new names can be substituted with 

 slight trouble when the work is finally revised for publication.
