boom its advertisers, they must speak for 

 themselves, but we would especially 

 remark on the advertisement of Mr. 

 Abbott H. Thayer in this issue. This 

 gentleman has made a special study on 

 Protective Coloration among Animals ; 

 his views were partially published in The 

 Auk of April and October, 1896. At 

 present Mr. Thayer is engaged in writing 

 a book on this subject and any photo- 

 graphs that our readers might be able and 

 willing to furnish him with we are sure 

 he will be very grateful for. 



Prof. T. J. Fitzpatrick, of Iowa City, 

 Iowa, has very kindly favored us with a 

 number of his pamphlets on the flowering 

 plants of that state. These pamphlets 

 are very interesting and we regret that 

 lack of space will not permit a further 

 reference to them in this issue. 



Pennsylvania is fortunate in possessing 

 in Governor Pennypacker an executive 

 who fully realizes the great importance 

 of the preservation of our forests. A 

 portion of his time this month has been 

 spent with Dr. Joseph T. Rothrock, For- 

 estry Commissioner, tramping over some 

 of our forest areas for the purpose of 

 making a careful inspection of the same. 



Mr. J. Warren Jacobs, of Waynesburg, 

 Pa., in his " Story of a Martin Colony" 

 recites in an extremely interesting manner 

 his efforts, which were attended ultimately 

 with success, in the establishment of quite 

 a colony of these birds. The Purple 

 Martin {Prog7ie subis) as we all know, in 

 thickly settled districts is no longer com- 

 mon and Mr. Jacobs during a period of 

 seven years from 1896 to 1902 erected 

 bird-houses for them and in every manner 

 catered to their comfort. The detail of 

 his work cannot be described here, but 

 suffice it to say that a census of his mar- 

 tin colony taken May 28th, 1902, states 

 the following : Rooms occupied, 72 ; 

 containing eggs, 50 ; containing both eggs 

 and young, 2 ; nests being constructed, 

 20 ; total eggs and young to date men- 

 tioned, 245. All interested in the study 

 of bird life should possess this pamphlet. 



It may be obtained of Mr. Jacobs, price 35 

 cents. 



Mr. Willard N. Clute has favored us 

 with a copy of his "Fern Collectors' 

 Guide." It is a volume of convenient 

 size for field work and covers in an 

 excellent manner the subject upon which 

 it treats. 



Dr. Carl Gegenbauer. 



Carl Gegenbauer, the famous Ger- 

 man anatomist, died at Heidelberg on 

 June loth, 1903. 



Carl Gegenbauer was born at Wurz- 

 burg on August 21, 18'2fi. He studied 

 in the gymnasium of his native city, 

 and was a pupil of Koelliker and of 

 Vircliow at the university of rhe same 

 place. He received his doctor's de- 

 gree in 1850, and began life as an 

 assistant physician in the "Wurzburg 

 Hospital, but soon abandoned medical 

 practice to devote himself exclusively 

 to anatomical studies. After study- 

 ing the organization of the infe- 

 rior animals of the Mediterranean 

 region, he became a private docent at 

 Wurzburg in 1854, was called thence 

 to the Chair of Anatomy at the Uni- 

 versity- of Jena, and was transferred in 

 the same capacity to the University of 

 Heidelberg in 1So3. Professor Gegen-

Early Risers. 



By Thos. G. Gentry, Sc.D., Philadelphia, Pa. 



While recovering from an attack of 

 typhoid pneumonia, many years ago, 

 sleep being banished from my eyelids by 

 the weariness incident to a protracted 

 illness, my early morning hours were 

 spent listening to the strains of music 

 which in the June breezes delightfully bore 

 to my bedside through the half-open 

 windows. 



Observing for some time that the same 

 feathered choristers were, by some good 

 genius, thus made to contribute to my 

 pleasure and happiness by drawing my
