552 MR. W. G. CLARKE ON NORFOLK NEOLITHIC 
of Twyford, who watched them for half an hour hawking 
along the valley between Twyford and Guist. 
It has also been seen hawking over the land between 
Paradise and Kendle’s farm, and along the stream in the 
direction of Bates’ Moor. 
The last records I have of the appearance of one bird is 
the 26th March, seen by Mrs. Bayfield, Mrs. Howell, and E. 
Keeler, flying across the Foxley road in the direction of the 
Hegg grazing grounds, and on the 28th March one was seen 
by Keeler hawking over the Hegg grazing grounds which he 
watched for some time, when it disappeared in the direction 
of Themelthorpe. 
April 28th, seen by W. Palmer, p. c., at 9 p.m., and again at 
11.30 p.m., when it passed within 30 yards of him at Twyford. 
May 3rd. Seen by Palmer and myself at n p.m. hawking 
over meadows by Hegg.

NORFOLK NEOLITHIC HARPOON-BARBS 
AND TRIANGULAR KNIVES. 
By W. G. Clarke. 
Read 2 8tJi January, 1908. 
In the 'Antiquary’ for September, 1907, Mr. A. E. Relph, 
M.R.C.S., L.R.C.P., pointed out that in all probability some 
of the Neolithic single-barbed arrowheads, and implements of 
similar form but unknown use, were originally made as harpoon- 
barbs, and the chipping of the specimens referred to certainly 
supports that view in many instances. It is not. however, 
applicable to all, and a single-barbed lance-head found by 
Mr. C. Chambers on the northern shore of Lake Lothing, 
Lowestoft, and another found by myself at Great Snarehill.
