Cooke’s ‘ Further Notes on the Birds of Colorado.’ !— This is a ‘ Sec- 
ond Appendix’ to Prof. Cooke’s ‘ The Birds of Colorado,’ published in 
1897, this, andthe ‘ First Appendix,’ published in 1898, being paged con- 
tinuously with the original catalogue. Several species are here added 
to the list of Colorado birds, making the number 387, of which 243 are 
known to breed. This is an addition of about 25 species during the three 
years since the publication of the original list. Many notes are also 
added respecting the distribution and breeding ranges of other species. 
Much space is given to notes based on the study of the collection of Col- 
orado birds made by the late Edwin Carter, representing “the work of Mr. 
Carter for more than thirty years. Much of the material was gathered in 
the immediate vicinity of Breckenridge, and the rest in Middle Park and 
South Park,” at altitudes of 7500 to 9500 feet. The ‘ Bibliography of 
Colorado Ornithology’ is continued to date. 
As showing the progress made in the study of Colorado birds, Prof. 
Cooke remarks (p. 220): ‘There are twenty-five Warblers given in the 
last edition of the A. O. U. Check-List whose range is said to be ‘ Eastern 
United States,’ or ‘Eastern United States to the Plains,’ thus not including 
Colorado in their habitat,” of which eleven have now been found in Colo- 
rado, and Prof. Cooke expects that the other fourteen will yet be found in 
that State. This large appendix of nearly 60 pages is provided with an 
index, and merits the high praise we gave the original catalogue (cf Auk, 
XIV, 1897, pp. 331, 332).—J. A.A. 
Economic Ornithology.—In the last number of this Journal (XIII, 
PP- 314, 315) attention was called to Dr. T. S. Palmer’s important con- 
tribution to the subject of Bird Protection, forming Bulletin No. 12 of 
the U.S. Department of Agriculture, Division of the Biological Survey. 
This was promptly followed by Circular No. 28 of the Division of the 
Biological Survey, also by Dr. Palmer, consisting of a ‘ Directory of State 
Officials and Organizations concerned with the Protection of Birds and 
Game,’ giving a list of the Fish and Game Commissioners of each State, 
and of each of the Provinces of Canada; also a list of National and State 
Organizations interested in this work, including their officers and ward- 
ens, with their addresses; and also a list of the Audubon Societies, 
organized especially for the study and protection of birds, with the 
addresses of their Secretaries.
