BirD MIGRATION AT SOUTHERNESS. (ics 
kept watch. During that time, sixty-seven species of birds came 
under observation—a rather large proportion, because, as a rule, 
they could not reckon on finding any more than from forty to 
forty-five in any given district in that period of time. His first 
observation was that of a party of no fewer than fifteen gray 
wagtails. That was a comparatively rare sight, the largest num- 
bers he had previously seen together being just two or three. 
They flew about a few minutes and then headed right into the 
clouds, thence aiming almost due south, or on a course that 
would take them past Anglesea. The next specimen he saw was 
the blue-headed wagtail. He had not seen this bird in life 
before, it being one of the rarest species in the district. On the 
Sunday he witnessed an extraordinary assemblage of titlarks, 
numbering many thousands. Where they came from he could 
not tell. He watched all day to see from what point of the 
compass they had arrived, but he failed to get a clue. When 
disturbed, these titlarks did not fly up in the air as is their usual ; 
they rather simulated the movements of mice, running about 
among the herbage and around rocks and stones. They re- 
mained all Sunday at the point; and next morning, when he 
looked around, not a dozen was to be seen of all the thousands. 
They had gone off during the night. About half-past twelve that 
same day, when he was looking across the sea, he saw five rooks 
coming along and going south; then some forty came along, 
half-an-hour later twenty more, and towards six o’clock nearly 
sixty. He had not before seen rooks coming across from the 
English side; but considering the time of day they arrived and 
that they came in separate bodies, he had every reason to believe 
that these rooks were on migration and had probably started 
their journey from some of the Danish or German forests. That 
Was not an unreasonable view, because along the east coast of 
England and Scotland rooks had been seen coming in from the 
ocean in swarms. Suddenly, on the Monday morning, a large 
number of swallows, probably eight hundred or a thousand, made 
their appearance, none having been visible before that. The 
great bulk were the ordinary swallow, a number were house 
martins. For an hour and a-half they circled about, when 
suddenly the house martins changed to the majority. Where the 
swallows went to he could not make out, but probably they 
went off singly or in a stream. The martins now in large num-
