ILLUSTRATED BY ELEGANTLY COLORED LITHOGRAPHIC PLATES. 
Whilst several beautifully 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, whieli shall be none the less true to nature, but 
whicli shall have, in addition to accuracy, the important quality of cheapness. With this object in view, we have em- 
barked in the enterprise, hoping that our ornithological friends and others will give it ample encouragement. 
This w'ork will be something more than a mere book of nests, eggs and birds. It will endeavor to bring into promi- 
nence 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 many years. The text, therefore, will mainly be the result of his own observa- 
tions and research. 
CONDITIONS OF PUBLICATION. 
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 wdll contain TWO magnificent chromo-lithograph ic plates, and average twelve pages 
of descriptive text. One of the parts will contain a Chromo Portrait of the Author, without extra charge. 
The price will be ONE DOLLAR per part, and in no case will subscriptions be received for less than the entire work. 
The work will consist of TWENTY-FIVE PARTS. The 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 
demand for the Birds, in connection with the Nests and Eggs, we have also figured them. After Part VI. the birds, in 
life-like colors, appear on every Plate,drawn by the best ornithological artist in the country — 3lr. EI> WIN SHEFPARU 
—and with the •2;ith Part, we will furnish all the Birds, on other plates, which belong to the nine Nests where they have 
not been figured. 
This makes one of the most beautiful, useful and instructive books ever published.
