Nature and the Camera. By A. Rad- 

 CLYFFE DuGMORE. Illustrated by pho- 

 tographs by the author. New York. 

 Doubleday, Page & Co., 1902. 



Mr. Dugmore's well-known nature pho- 

 tographs are a sufficient guarantee of his 

 fitness to prepare a manual on methods in 

 nature photography, and he has placed the 

 lesson of his own experience clearly before 

 his readers. There are chapters on the 

 outfit, exposing, developing, etc., photo- 

 graphing birds and their nests, animals, 

 reptiles, insects, fish, trees, shrubs and 

 flowers, all so well illustrated as to show 

 that the author practices what he preaches. 

 Particularly would we call attention to the 

 photograph of the Woodcock facing page 

 22, which, made with an isochromatic plate 

 and a ray filter, and printed in sepia, is as 

 beautiful and satisfactory a picture of this 

 bird on its nest as we ever expect to see. 



The photographs of reptiles, fish, etc., 

 are equally good, and serve to confirm our 

 opinion that Mr. Dugmore is the leading 

 nature photographer in this country. A 

 slip on page 7 makes a decrease of one-half 

 in the diameter of the diaphragm, calls for 

 only twice, instead of four times as long an 

 exposure, and may lead the amateur into 

 difficulty if it be not corrected. — F. M. C. 



The Development of Color in the De- 

 finitive Feather. By R. M. Strong; 

 Bull. Mus. Comp. Zool., xl. No. 3; 

 pp. 146-186, pll. i-ix, Oct., 1902. 



Ornithologists constantly deal with the 

 color of birds' plumage, but the character 

 of the color, whether it be due to pigments, 

 feather-structure or both, are matters to be 

 determined by the histologist and physicist. 

 The ornithologist can describe results, but 

 a determination of the processes which have 

 brought them to pass requires a special train- 

 ing and knowledge of technique, such as 

 fevv ornithologists possess. It was therefore 

 exceedingly fortunate that Dr. Strong's in- 

 terest in birds should have led him to de- 

 vote portions of two years, while working 



in the Harvard Zoological Laboratory, to a 

 study of the colors of feathers. The results 

 of his labors form a contribution to science 

 of the first importance and are of especial 

 interest to students of birds. 



It is not possible at this time to present 

 even an abstract of Dr. Strong's researches, 

 but we may at least state that they not only 

 revealed no evidence of repigmentation of 

 a grown feather or of a change in the color 

 of existing pigment, but induced him to be- 

 lieve that changes of this character are not 

 possible. — F. M. C. 



Field Notes qn some Bahama Birds. By 

 J. L. BoNHOTE. From the 'Avicultural 

 Magazine,' Vols. VIII and IX. Brigh- 

 ton, England, 1903. 8vo. Pages, 33; 

 plates, 6. 



The birds of the Bahamas, so far as 

 specimens are concerned, are well known; 

 but few of the many naturalists who have 

 visited these islands have had Mr. Bonhote's 

 opportunities to study Bahaman birds in 

 their haunts. His ' Field Notes,' therefore, 

 form an acceptable and important con- 

 tribution to our knowledge of Bahaman 

 bird-life. 



Six excellent photographs from nature of 

 birds and birds' nests add not a little to the 

 interest and value of this paper, the picture 

 of the Noddy on its nest being an especially 

 good bit of bird photography. — F. M. C. 



A Partial Bibliography of the Eco- 

 nomic Relations of North American 

 Birds. By Clarence M. Weed. Tech- 

 nical Bulletin, No. 5, New Hampshire 

 College Agricultural Experiment Sta- 

 tion, Durham, N. H. 1902. Pages 

 139-179. 



Professor Weed has here brought together 

 a useful collection of titles of publications re- 

 lating directly or indirectly to the economic 

 relations of North American birds. Be- 

 ginning with Wilson, in 1808, he has 

 diligently explored the literature of orni- 

 thology, entomology, and agriculture for 

 titles bearing on his subject; and many of
