suburban brickfields. ‘There are, indeed, few localities 
where water is present that this Wagtail does not visit ; 
and this means that the bird may be met with all 
along the Thames, by the various canals and the many 
ornamental sheets of water and reservoirs that abound 
in the Metropolis. I have no personal records of the 
species from the fountains in ‘Trafalgar Square, but the

visit inner London, seldom remaining long, and by no
