ARDEIDAE—HERONS. 183 At present they occupy some tall elms growing upon an island in the largest sheet of water in the Park. In 1869 there were about thirty pairs ; in 1883, about twenty-five ; in March, 1884, forty-three nests were counted (47. 94) ; and in April, 1887, about thirty-eight. There have since been a few more added. Mr. Fitch says (50. ii. 179) : " It is satisfactory to learn that the free admission of visitors to the Park, except that the path by the lake is closed in May and June during nidification, has not apparently resulted in any injury to the Heronry." An interesting account of a visit to this Heronry, was given by Mr. Hart- ing in Science Gossip for April, 1869, and also in his Sketches of Bird Life (1883, p. 266) ; while a small sketch of it (here reproduced) appears in Mr. Buxton's Epping Forest (47. 94) ; and a larger one by C. Whym- per in Seebohm's Brit- ish Birds (ii.' p. 472). Through the kindness of Mr. E. A. Fitch, I am enabled to introduce as the frontispiece of this work, a lithographic re- production of another drawing of this Heronry, made by Mr. C. Whym- per in 1885. The orig- inal is in Mr. Harting's possession. The next Essex He- ronry deserving notice is that in the park surrounding Boreham House, the residence of Lieut. J. L. Tufnell-Tyrell. Mr. Fitch writes (50. ii. 174) :— " This Heronry is not now in its old position. The birds used to build where the Rooks do now. immediately behind Boreham House ; but about seven years ago this colony became reduced to a single nest, and the old bird was shot whilst sitting. In 1884, the Herons first nested in West Mead Grove, a small grove planted as an apple orchard in 1842, and subsequently with oak, spruce firs, and a few miscellaneous trees, including some Scotch pines. The grove being only about 400 yards from the river, and on about the same level, the soil is very wet, like all the grass-land of the Chelmer Valley, and consequently the apple trees soon cankered and died out, although one or two still remain, and the growth of the firs has been very slow. In company with the Rooks, the Herons have taken possession of these last-named trees. In 1886, there were nine nests, but thirty young Herons were destroyed in one day, and several more on other occasions. In 1887 the position was about the same, and although the persecution was continued, there appears to be the same number of nests this pre- sent year." In 1889, there were six nests, from which ten eggs were taken. Of the Brightlingsea (St. Osyth) Heronry, Mr. Fitch says :— " In Yarrell's British Birds and other works, mention is made of a Heronry at St. Osyth, but this appears to have been a mistake. The only Heronry in the
