166 THE ESSEX NATURALIST. my head towards the sea, but although I trained my glass on to it I remained puzzled, and dismissed the matter from my thoughts. A fortnight later, 27/11/27, I returned to the fleet, and again found the gull in the same position, so I decided to have another look at it, but before my telescope was in position, it rose and flew straight down the fleet and over my head. As it passed, as a forlorn hope, I put my glass on the bird, which, fortunately, caused it to turn over in its flight, giving me an excellent view of the wings in a splendid light, and to my surprise I could see that they were devoid of black markings. Instantly I knew I had seen one of the northern-breeding gulls. It was clearly an Iceland Gull as its size was about the same as that of the Herring Gull. Coot (Fulica a. atra L.). Pitseahall Fleet was the only locality where the species was seen in any numbers, a count, made on 24/10/26, showing that there were present from 150 to 200 birds. Similar numbers were seen here on various occasions. At some localities, such as Pitseahall Fleet and Corringham Marsh, the species was found throughout the year, but others, such as Mucking and Fobbing Marshes, appeared to be deserted after the finish of the nesting operations. It is of interest, in view of the rapid changes being made, that the Coot still nests at Dagenham Gulf, where young were seen on August 7, 1926.

RETROSPECT. The writer, in reviewing the series of papers which have been contributed on the subject, realizes how much more might have been done, how many more questions might have been answered. On the other hand this is the first occasion that such a piece of work has been accomplished in Essex, and perhaps in any English county. Seven years is a good slice out of a human life and
