ILLUSTRATED BY ELEGANTLY COLORED LITHOGRAPHIC PLATES. 
Whilst several beautifiilly illustrated books on the birds ot our country have been presented to the public from time 
to time, it is much to be regretted that no regular work, containing, proper delineations of nests and eggs, had made its 
appearance, excepting a large folio at $5 per part. 
When we consider the interest manifested by the youth of our land in that highly attractive department of Orni- 
thology of which it treats, we are led to believe there is room for another, -which shall be none the less true to nature, but 
w'hich shall have, in addition to accuracy, the important quality of cheapness. , With this object in view, we have em- 
barked in tbe enterprise, hoping that our ornithological friends and others will give it ample encouragement. 
This work will be something more than a mere book of nests and eggs. It will endeavor to bring into prominence 
those interesting and curious phases of bird-life which are present during the breeding-period, and which have been the 
principal study of the author for the past ten years. The text, therefore, will mainly be the result of his own observa- 
tions and research. 
CONDITIONS OF PVBLICAIION. 
The work will be issued in monthly parts, quarto size, and sold only by subscription. Each part wall be printed on 
super-calendered plate paper, and will contain TWO magnificent chromo-lithographic plates, and about twelve pages 
of descriptive text. One of the parts will contain a fine Chromo Portrait of tee Author, without extra charge. 
The price will be ONE DOLLAK per part, and in no case will subscriptions be received for less than the entire work. 
The work will not exceed TWENTY-FIVE PAETS. Tbe design of the author is to figure the typical nests of our 
species, and the most marked variations therefrom. Since issuing the first three parts of this work, there has been such 
demtind for the Birds, in connection with the Nests and Eggs, we have' decided hereafter to figure them. Parts IV., V. 
and VI. each contain birds on one of the Plates. After Part’VI. the birds, in life-like colors, will appear on every Plate, 
drawn by the best ornithological artist in the country — Mr. ED if IN SUEPEA11I>. 
This will make one of the most beautiful, useful and instructive books ever published.
