86 BRITISH BIRDS. [vol. vi. 



arc such rarities as Eversmann's Warbler and the Siberian 

 Chif^chaff. The curious absence of the Starling. SkyT.ark, 

 and Chaffinch as reqnlar autumn-visitors is worthy of note. 

 Apparently by an oversight the Gannet is omitted from the 

 list of Sule Skerry birds. 



The last chapter gives an account of an abortive visit to 

 Ushant, \\hich island certainly must be, from its position, 

 an ideal one for observing migrants, as it should catch the 

 westerl^^ and southerly coasting streams. Mr. Clarke was 

 just able to prove that much migration does take place there, 

 before he was hustled out of the country as a spy ! The rest 

 of his vacation was spent on Alderney, where a fair amount 

 of migration was witnessed during his short stay, though it 

 was impossible to say whether the birds were travelling west 

 or south. Even in such a limited time he A\as able to expand 

 the status of many species, and add a few new ones, which 

 shows how very little we know of the birds of the Channel 

 Isles. 



In conclusion, we may say that we have nothing but praise 

 for Mr. Clarke's book, and congratulate him on bringing it to 

 such a successful conclusion. It is eminently the product 

 of a worker ; to the beginner in the study of migration it 

 will point out the right lines of investigation ; to the student 

 it gives much interesting matter for consideration, and it 

 will be read with great pleasure by every ornithologist.
