use has been made of it by others, including Dr. Clark in the preparation 

 of his report on the birds of the 'Albatross' cruise of 1906 (re%aewed 

 above), but no full report upon it has been published until now. In 

 the meantime some of the birds first obtained in Korea by Jouy have 

 already been recorded by others, and in order to secure to him the proper 

 results of his labors this report is now offered in its present, as the author 

 states, not wholly satisfactory form. It is, however, the most important 

 contribution yet made relating distinctively to Korean ornithology. —

Walter's 'Wild Birds in City Parks.' — The fourth revised and enlarged 

 edition of this "handy pocket guide to the birds" ^ has been greatly ex- 

 tended since our notice of the first revised edition in 1903 (Auk, XX, p. 316), 

 the number of species treated having been increased from 100 to 200, the 

 amount of matter more than doubled, and the table of comparative distri- 

 bution greatly extended, it now covering the northern tier of States from 

 Maine to Illinois and Missouri. The note to the present edition states that 

 the entire subject has been thorouglily revised, "with the end in view of 

 making the book useful in all localities in northeastern United States from 

 the Mississippi to the Atlantic coast." That the book has proved useful 

 is to be inferred from the statement that the present printing is the "eight- 

 eenth thousand." — J. A. A. 



Collinge on Food Habits of the Rook.- — This investigation, which has 

 been carried on more like similar studies in the United States than any 

 other European work on economic ornithology we can recall, is based on 

 the examination of 830 stomachs of Rooks, collected at all seasons in 41 

 counties of England and Wales. The bulk of the food taken from these 

 gizzards was grain, chiefly wheat. A comparatively small amount of 

 weed seeds was present, and much acorn mast, some gooseberries, cur- 

 rants, grass roots and potatoes complete the list of vegetable foods. Ani- 

 mal food averaged in the 12 months only 15 per cent, of the total food 

 contents of the gizzards. The proportion varied from 1 per cent, in Janu- 

 ary to 40 per cent? in July. Beetles, their larva?, and caterpillars were the 

 principal items. Remains of the following vertebrates were found: long- 

 tailed field mice {Mus sylvaticus), rat (?>, rabbit, and young birds, includ- 

 ing blackbirds. Blackbirds' and pheasants' eggs were taken from 1 and 5 

 stomachs, respectively. From these details it is evident that the Rook
