[Second ten-year Index to tlie ( Condor.’ Vols. xi.-xx., 1909-1918. 
By ,T. H. Pemberton. Hollywood, California, 1919.] 
Readers of tlie ‘ Condor 5 and Members of Cooper Ornitho¬ 
logical Club ought to be very grateful to, Mr. Pemberton 
for his most carefully constructed and ingenious Index to 
the ten volumes of the ‘Condor,’ from 1909 to 1918. The 
preparation of it occupied eighteen months of his time, but 
the result appears to be extremely satisfactory, and all tlie 
information contained in the volumes can be referred to at 
once, without any trouble. 
The longest article contained in the two volumes of the 
‘Condor’ under review is that of Mrs.Merriam Bailey on her 
wanderings in the Dakota Lake region, in which she recounts 
in a charming style her experiences and observations on the 
birds of the western prairie region. A new feature of the 
‘ Condor ’ is a series of autobiographies, the longest and most 
important of which is that of Mr. H. W. Henshaw, until 
recently the Chief of the Biological Survey at Washington. 
In his early days, in the seventies and eighties of the last 
century, Mr. Henshaw was attached to the United States 
Geological and Geographical Survey and travelled extensively 
all over the Western States. It was during these years that 
he amassed the large collection of American birds which sub¬ 
sequently, through the generosity of the late Mr. Godman, 
found a home in our Natural History Museum at South 
Kensington. 
The 1919 volume contains, in addition, a number of 
articles on the nesting-habits of some of the less well-known 
western birds, generally illustrated by excellent photographs 
beautifully reproduced. Such are the accounts of the 
nesting of Townsend’s Solitaire (Myadestes townsendi) near 
the snow-line on Mt. Shasta in northern California by 
Mr. W. L. Dawson, of the Short-eared Owl in Washington 
State by Mr. E. H. Kitchin, and of the Red Crossbill in 
British Columbia by Mr. J. H. Munro ; Mr. G. Willett,
