(1.1910.246), and on the Isle of May on the iith were 

 a Whitethroat, a Garden Warbler, quantities of Willow- 

 warblers, a Sedge-warbler, an adult White Wagtail and a 

 Ringed Plover. On the I4th a Two-barred Crossbill was 

 procured on the Flannans, and a Ruff, a Reeve, and a 

 Spotted Redshank were seen at Waulkmill Glen Dam 

 (2.ii. 142). Yellow Wagtails were passing Kirkliston on the 

 i 5th and 2Oth, and on the latter date a Lesser Whitethroat 

 arrived on Fair Isle and two Hoodies on Whalsay Skerries. 

 On the 22nd the Tree-pipit migration began at Largo, and 

 " simply enormous flocks of Lapwings " were seen there, 

 while the last Sedge-warbler is noted at Beith. On the 

 23rd in the middle of Fife, about the watershed between 

 Forth and Tay, a large flock of Sandwich Terns flew over 

 about 5 P.M. going south and calling as they flew. Next 

 day the Crossbills left Fair Isle, where they had been in 

 small numbers since the 8th. A flock of about fifty Pied, 

 and at least one Yellow Wagtail was seen on the coast near 

 Aberdeen on the 25th, and two days later three Spotted 

 Redshanks were seen at Waulkmill Glen Dam (2.11.142), 

 and Great Northern Divers returned to Tiree. On this day 

 and the 28th Sand-martins on passage are recorded from 

 many places, sometimes in large numbers. The 2 9th 

 brought some migrants to our shores, many Willow-warblers 

 arrived on Fair Isle and some at North Unst, flocks of 

 White Wagtails were passing south in Tiree, and Wigeon 

 arrived in the Cromarty Firth and Luce Bay. A Spotted 

 Redshank was seen at Donmouth on the 3Oth (1.1910.249), 

 small numbers of a good many species appeared on Fair 

 Isle, and a Goldcrest and a Wryneck struck the lantern at 

 North Ronaldshay. On the last day of the month a 

 Wryneck occurred on Fair Isle. 



September. With the advent of September the anti- 

 cyclone which had occupied the middle region of the 

 Atlantic expanded north-eastwards and embraced the entire 

 area of the United Kingdom. Thenceforward for nearly 

 four weeks an anticyclonic type was maintained over these 

 islands. Frequently the area of high barometer readings 

 was of enormous extent, stretching westwards right across 

 the Atlantic to Newfoundland and beyond, and eastward
