found its nests there, in dead trees standing adjacent to cultivated areas out Drayton way. On Bell- 
trees Station, near Scone, N.S.W., during March of this year (1907), I saw several of the birds hovering 
over the beautiful open country there, and no doubt they breed in such an ideal spot. The four eggs 
under notice are beautifully blotched, and Specimen A. measures = 1°50 x 1°22.

WEDGE-TAILED EAGLE, 
Uroaetus audax, Latham. 
This beautiful set of 2 eggs, which are very round specimens, was taken from a huge nest in a 
Flooded Eucalypt (Eucalyptus rostrata), on the north bank of the Orara River, near Coutt’s Crossing, 
ten-miles from South Grafton, N.S.W., on the 15th of October, 1892. The set was taken by Frank 
and Sid. W. Jackson.. We found other nests of this eagle on the Clarence River, but they were usually 
old ones. I visited a large nest once during the season 1897, which was situated on the horizontal 
branch of a very large Stringybark Eucalypt (Eucalyptus macrorhyncha) on the Black Mountain, on the 
road between Grafton and Armidale. The nest must have been there for many years, judging from 
the pile of debris which had accumulated beneath it, which was then over eighteen inches deep, and 
around which were scattered hundreds of bones and the skulls of various small animals. Specimen A. 
measures = 2°72 X 2°30. Specimen B. measures = 2°67 x 2°30. 
Splendid set of 2 eggs, not so rounded as those of the former set, No. 255, and the markings are 
more evenly distributed. ‘Taken by J. Watson at Buckiinguy Station, Western New South Wales, on 
the 24th of July, 1900. This fine bird, like many others of its family, is rapidly becoming extermi- 
nated in the western parts of New South Wales, owing to the great number that are being indirectly 
poisoned through the attempts which have been made to try and kill the rabbits, which have now 
become such a great pest to the pastoralists. Not only the hawk family, but also various other species 
have been killed in thousands through partaking of set baits, and drinking poisoned water, which had 
been placed for the rabbits. Hawks’ eggs will be very rare items before long if the old-fashioned 
scheme of poisoning these rodents still continues. Of the set under notice Specimen A. measures = 
2°87 x 2°20, Specimen B. measures = 2°97 x 2°34.

WHITE-BELLIED SEA BAGLE, 
Haliaetus leucogaster, Gmelin. 
This plain and unpretentious looking clutch of 2 rare and perfect eggs, was taken near the Govern- 
ment Experimental Farm at Grafton, Clarence River, N.S.W., on the 14th of August, 1898, by J. 
McEnerny, Frank and Sid. W. Jackson. (See A. J. Campbell’s book, page 18, and illustration.) We 
made two visits to the nest before we succeeded in taking the eggs from it, and it was placed at an 
altitude of over 100 feet in a large Spotted Eucalypt (Eucalyptus maculata), and was reached by the 
aid of my tree-climbing ladder, and the eggs were taken by my brother, Frank T. A. Jackson. (See 
accompanying photographs.) The nest contained three eggs, one of which got broken in transit, and was 
quite beyond my skill to repair ; it wasan unfortunate accident to us, and it took me some time to forget 
such an irretrievable loss. The nest was a wonderful structure, and measured nearly seven feet across 
by five feet thick, and bulky enough to fill a dray, some of the sticks used in its construction being as 
thick asa man’s wrist. It was lined with many layers of green Eucalyptus leaves, which tend so 
frequently to discolor the eggs, and they are used, no doubt, for the purpose of generating heat. It is
