second fortnight the temperature rose and southerly winds 

 predominated ; many of our own Waders were on the move,

 movements were intensified, and in addition large arrivals of 

 migrants took place, including several uncommon visitors.

 September continued in lessening measure, Turdince pre-

 and west, and the principal feature of this period was the 

 arrival of winter visitors. In the latter half of the month 

 the temperature fell, the weather was very unsettled, and the
