I PUBLICATIONS OF SPENCER F. BAIRD. 



1844. Baird, Spenceu F.— Continued. 



"To the purpose of copying a coarse print, a piece of music, an embroidering pattern or a 

 leaf this process is admirably adapted. It is for the latter object that the art has been 

 mostly used by the writer, who last summer copied leaves of nearly all the trees and shrubs 

 of Cumberland County (Pennsylvania), amounting to nearly two liundred species. These 

 photographs are as valuable for scientific purposes as good engravings of the same would be, 

 perhaps more so, as not only is the outline perfectly given, but in most cases the fine and 

 delicate nervation, whose arrangement frequently forms a specific character, is distinctly 

 preserved." 



This collection of leaf photographs, still preserved in tht; National Museum, has been one 

 of the standard resources of American paleophytologists, and has been used in the prepara- 

 tion of many of the works on the Fossil Botany of the United States.

After introductory remarks on the geology and topography of Cumberland County and the 

 relations of peculiarities of vegetation to the soil, a list of the trees and shrubs is given, 

 with common names, stations, and notes regarding abundance. The whole number of species 

 enumerated is 150, 20 of which had been found in Chester County.

1845. Baird, Spencer F. Catalogite of birds found in the neighborhood of Carlisle, 

 Cumberland Co., Pa. <^Lii. Rec. and Journ. Linnwan Assoc. Pennsylvania 

 College, i, No. 12, Oct., 1845, pp. 249-257. 

 A revision of No. 2. 



A list of the species of birds collected by the writer between 1840 and 1845 (with a very few 

 exceptions) within a few miles of Carlisle. "None are admitted without having been actu- 

 ally killed and preserved ; in no case have any been admitted on the authority of others. A 

 residence nearer the Susquehanna would no doubt liave enabled us to increase this number 

 considerably, as wo have heard of several not in this list which have been killed about Har- 

 risburg. Some of these will be found in a catalogue of additional species procured at Mari- 

 etta, Pa. (25 miles south of Cumberland Co., by Mr. J. Libhart), most if not aU of which 

 touch on our eastern border. The nomenclature employed is based on that of Prince Bona- 

 parte, . . . with the additions, however, of the authority for each species, and various alter- 

 ations called for by a strict regard to the law of priority. The name immediately succeeding 

 each species is that of its first deseriber, aud if in parenthesis, under a different genus. The 

 second name is his who first placed that particular specific appellation under its present 

 genus. A (t) prefixed shows that this bird breeds here." 



The list of .species is supplemented by references to Audubon's names, by the common 

 names, and notes on relative abundance and season of appearance. The paper is summed up 

 as follows (p. 257) : 



"Total of species in Cumberland Co 202 



of which : — Breeding 104 



Summer visitors 66 



Resident 38 



Transitory ui spring 90 



Seen in autumn only 8." 



The Marietta list includes 9 species, and 6 others are mentioned "of whoso existence in our 

 vicinity we have had strong proof (but) are not included for want of specimens." None of 

 these are included in the summation. 

 The following combinations appear in this paper for the first time : —
