concerned, it was on all occasions quite impossible to tell 

 from what quarter the birds approached the ship after dark- 

 ness had set in. This I much regretted, for I was particularly 

 wishful to ascertain whether the E. to W. movements 

 were performed during the night as well as the day. I did 

 ascertain beyond a doubt that Rooks, Jackdaws, Lapwings, 

 Ring-Plovers, and a number of wading birds did move in 

 this direction during the night-time, and I think that there 

 is strong presumptive evidence that the great movement on 

 the night of the 17th-18th of October was wholly, or. in 

 part, from E. to W. 



The nocturnal passage southwards during the latter part 

 of September has already been alluded to, and but little 

 more remains to be said concerning it. On the night of the 

 18th of September and during the earliest hours of the 19th, 

 Redstarts, Pied Flycatchers, Thrushes, and an adult male 

 Kestrel — a somewhat unusual nocturnal migrant — were at 

 and around the lantern, along with other species unidentified. 

 This was the commencement of a movement southward 

 which was in full swing all the following day. 



Soon after midnight on Sept. 20th a large party of Sky- 

 larks appeared, accompanied by other small Passerines. A 

 considerable number struck the lantern and fell into the 

 sea, the wind being moderately strong and the ship ridino- 

 with her beam to it. 



At 8.45 p.m. on Sept. 22nd a number of Wheatears arrived 

 and continued, to fly around while the sky remained overcast. 



On Sept. 25th between 1 and 4 a.m., during light rain, 

 many Wheatears, Redstarts, Pied Flycatchers, Whitethroats, 

 Willow-Warblers, Tree-Pipits, Skylarks, and a Richard's 

 Pipit (all of which were killed at the lantern), doubtless 

 with other species, were flying round the vessel, and great 

 numbers struck the glass and were lost in the sea. 



On Sept. 29th, between 2 and 5 a.m., Blackbirds (those 

 killed being immature males), Redstarts, Pied Flycatchers 

 Wheatears, Goldcrests, and Skylarks were present in great 

 numbers, and hundreds struck the lantern and fell over-
