the Tree-sparrow was likewise breeding in the Rhymer's Tower, the 

 erstwhile abode of the True Thomas at Earlston. — George Bolam, 

 Alston, Cumberland. 



Occurrence of the Knot inland. — On 29th August 1914 I 

 saw two Knots {Tringa camitns) at Balgray Reservoir, East 

 Renfrewshire. Only in one other autumn in the last twenty years 

 has this littoral species been observed here. Probably the condi- 

 tions obtaining at this reservoir are seldom such as suit the bird at 

 the time of its passage in the second half of August. The water 

 has either not receded far enough, or it has receded too early, and 

 allowed the muddy margin to harden.— John Robertson, Glasgow. 



Migration of the Ringed Plover in East Renfrewshire. — 



Small parties of Ringed Plovers are frequently seen on passage, in 

 May, at the East Renfrewshire reservoirs, but at that season the 

 reservoirs are generally full, showing no muddy or sandy margins, 

 consequently there is no inducement for the birds to linger were 

 they inclined to do so. In autumn matters are somewhat different. 

 The birds are not in such great haste, and if the reservoirs, Balgray 

 in particular, have fallen sufficiently low, we are sure to have a 

 leisurely visit of Ringed Plovers. The first birds appear at Balgray 

 sometimes as early as the 30th July, the maximum number, about 

 thirty birds, is reached at the end of August, and usually the 

 laggards have passed on by the end of September. Both adults and 

 birds of the year are noticed. From the lightness and purity of the 

 mantle, even allowing for the young, it seems likely that some at 

 least, of these birds are of continental origin, and what perhaps 

 supports this view is the fact that the spring passage takes place 

 during May. In "Clyde" the Ringed Plover begins to lay early in 

 April. — John Rohertson, Glasgow. 



Green Sandpiper in "Clyde" in Spring.— As a spring 

 record of the occurrence of the Green Sandpiper in the Clyde area 

 is somewhat rare, it may be well to state that a single bird of this 

 species was observed by me frequenting a mud patch on the 

 Allander, a tributary of the Kelvin, on 27th March, and on several 

 subsequent occasions in the same neighbourhood, the last being on 

 1 6th April. Autumn records for the Kelvin were one on 6th 

 August, and again a single bird on 26th and 27th September, no 

 doubt the same.— D. Macdonald, Garnethill, Glasgow. 



Green Sandpiper in East Renfrewshire.- On 22nd and 

 29th August 1914, I saw a Green Sandpiper, and on 5th September 

 apparently the same bird along with another at Balgray Reservoir,
