the cost of such completion." We applied to Dr. Emmons for aa 
estimate of the remaining expenses incident to the completion of the 
3d volume and received the papers herewith communicated and mark- 
ed D. There are several omissions which we have supplied below 
and w^e now present our own estimate of the expense of completing 
the volume in question, according to existing contracts. 
Coloring of 60 plates of fruits, at $1.50 per plate, 
each 3,000 impressions, $7,500 00 
Insects, one plate paid for, both for drawings, en- 
graving, and coloring : 
19 plates, containing 453 figures, drawing the same at 
$1.50 each, $679 50 
Engraving the same, at 3.00 each 1,359 00 
$2,038 50 
30 plates, containing 750 figures, drawing 
the same, at $1.50, $1,125 00 
Engraving the same, at $3, 2,250 00 
3,375 00 
Coloring 46 plates of insects, at $1.50 per plate, each 
3,000 impressions, 6,900 00 
Lettering 49 plates of insects, at $3.50,.. $17150 
Printing 49 plates of insects, 3,000 im- 
pressions of each, at $45, 2,205 00 
Paper, (say $30 for each plate) 49 plates, 1,470 00 
3,846 50 
Printing and paper for 3,000 title pages, 76 25 
$23,736 25 
We do not include in the above any estimate of charges for print- 
ing and binding, as these are paid for from the general appropriation 
for the above purposes, and are understood to be under the control of 
a special contract ; and above all, as from the length of time that 
this volume, and also Mr. Hall's second one on Palaeontology, have 
been in press, they probably have been either partially or w^holly paid 
for. We doubt the propriety Dr. Emmons' adding any new matter 
as proposed in his letter, how^ever valuable it may be. There cer- 
tainly should be some terminus.
