Mr. Clarke is peculiarly well qualified to write on the 

 migration of birds, for he has made the closest study of 

 the subject for aome thirty years, and in 1903 prepared the 

 digests of the several annual Reports of the Migration 

 Committee of the British Association, of which he became a 

 member in 1883. While engaged upon this task he found, 

 that a much greater number of observations than had been 

 already made were necessary for safe generalizations, and he 

 therefore decided to devote his spare time to visiting those 

 excellent observation-stations which Great Britain, from her 

 geographical position, possesses in abundance. After a 

 somewhat unlucky trip to Ushant in 1898, Mr. Clarke 

 obtained leave to pass a month on the Eddystone in 

 September and October 1901, to study the cross Channel 

 migration. At the same period of 1903 he spent a month on 

 the ' Kentish Knock ' Lightship, corroborating and enlarging 

 upon his Eddystone experiences, and viewing the extra- 

 ordinary east to west movements across the North Sea. In 

 1904 the Flannan Isles, to the west of the Hebrides, were 

 chosen for observation-purposes, while Sule Skerry^ to the 

 north-west of Orkney, was visited for a few hours during 

 the voyage home. The year 1905, however, provided the 

 greatest success, when Fair Isle, between Shetland and. 

 Orkney, was visited ; for not only were a marvellous number 

 of rare species proved to touch there on passage in autumn, 

 but several occurred that were new to the British and Scottish 

 lists. Accounts of this expedition and others subsequently 

 undertaken are given at length in three chapters. Two
