VI MEMOIR. 



eggs, and he was then particularly interested in the Phylloscojpi, 

 or Willow Warblers, on which group of birds he wrote an elaborate 

 paper in the "Ibis," for 1877 (pp. 66—108). At all times 

 Warblers interested him immensely, and he never left off the 

 study of these puzzling birds. 



In 1875 he went with Mr. J. A. Harvie-Brown to explore the 

 Petchora River in North-eastern Russia. The travellers met 

 with considerable difficulties, but came back to England with a 

 rich harvest of skins and eggs, the most interesting being those 

 of Anthus gustavi and PJujlloscopiis tristis, of which some nests 

 and eggs were obtained. The great prizes were the eggs of the 1 

 Grey Plover (Squatarola helvetica), and the scarcely less rare 

 eggs of the Little Stint {Tringa minuta). With these discoveries 

 the expedition of Henry Seebohm and J. A. Harvie-Brown will 

 be for ever connected. A most interesting account of the 

 journey was published by Seebohm in a separate work, "Siberia 

 in Europe." 



In the spring of 1876 he made an expedition to Holland, and 

 spent the month of May at Valkensvaard, and in the autumn of 

 the same year he visited Heligoland, with Mr. Frank Nicholson, 

 and they were kind enough to ask me to accompany them. This 

 expedition to the wonderful island rock (I can scarcely believe 

 that it is twenty years ago since we were there) is one of the 

 pleasantest memories of my life. The interest of meeting with 

 Gatke, the wonderful variety of the birds, the finding one's self 

 face to face with the phenomenon of migration, all combined to 

 make the visit a notable one, and no better account has ever been 

 given of a migration flight than that of Seebohm, in the " Ibis," 

 for 1877 (p. 156), where he describes our experiences in Heligo- 

 land. AVhen we left, he hoped to bring out an English edition 

 of Gatke's notes on the ornithology of the island, and at that 

 time he wrote : — " Mr. Gatke's work on the Birds of Heligoland 

 is making fair progress ; and he has entrusted to me the task 

 of translating it into English, and editing it in this country ; so 

 that it is to be hoped that within the next twelve months the full 

 details of his observations, made during the last five-and-twenty 

 years in this wonderful little island, may be made public." 

 Gatke's work appeared in 1891, and an English translation by 

 Mr. Rudolph Kosenstock in 1895.
