430 holmes: bronze implements, etc., in the -west riding. 
Close, when crossing the course of the River Aire, the workmen 
uncovered a series of black oak piles deep in the river bed, and 
a workman found a stone object 3 in. long, 2^ in. broad. It looks 
like an Irish lake net sinker, formed from a used up hammer. For 
a further account of finds of bronze celts, see a paper published by 
the Yorkshire Geological and Polytechnical Society, 1881. 
About 1870 a well-formed stag-horn pick-axe was dug up in 
Grove-road, Ilkley, about 15 feet deep. This has similar features 
showing use to those found by Canon Greenwell at Grime's Graves, 
Norfolk. 
About that time Mr. Joseph Lund, digging in his garden, on the 
edge of the moor, turned up a well-formed thumb-flint, about 1^ in. 
diameter. It is round and finely flaked at the edge. A similar one 
was found by Mr. Dresser in his garden at Adel. Both are perfect. 
Flint flakes are not uncommon upon Ilkley moor, but arrow-head and 
other forms though occasionally found are very rare. Mr. F. W. Fison, 
of Ilkley, has a small collection. Flint is not native at either Adel or 
Ilkley. The wolds, some 50 or 60 miles off, are the nearest, flint fields. 
At Adel, between 1865 and 1875, a large series of flint-flakes, well- 
formed arrow-heads, scrapers, and other implements were discovered 
at the Adel Reformatory by youths when " taking in " the rough moor 
land. Most of the articles went to the Leeds Philosophical Museum 
where they still are ; I obtained some ; among which, in 1878, was a 
well-defined core, a body from which flakes and arrow-heads were 
struck. These are in the Leeds Public Museum. The whole (?) of 
these flint finds at Adel centered about one high stone (still there), 
as though it were the workshop of the manipulators. This area being 
pretty well cleared of flint ; few or none are now discovered. 
From Rombalds Moor to Adel, and so on, east to the Vale of 
York, a line of high moorland runs to Moortown, Shadwell, 
and Barwick. Along this line a number of pre-historic discoveries 
may be registered within the last ten years. There in the February 
of 1879, a labourer ditching in a fiehl between Potter-Newton and 
Meanw^ood, in a rather low clay bed, discovered a fine well-formed 
stone hammer head 8 1 inches long, 3k thick, and 3f across head end, 
sloping gradually to the cutting edge. The hole drilled for the shaft is
