Tests of Water Hardness : — 
Scrafton Beck, below the village, y°, Clark. 
River Cover at Coverham bridge, io-ii°. 
River Ure, at West Tanfield bridge, 13 0 . 
Bishopdale Beck, below Kidstones, 9 0 . 
At 7 p.m. the same day,' after ten hours heavy rain, when 
Bishopdale beck was estimated to have increased to six times 
its former volume, the hardness was reduced to 7 0 . 
A gradual increase in hardness as the water travels down- 
wards was shown during the same period by the Wharfe, 
which, after much rain, had 6-7° at Raisgill Hagg at 8 a.m., 
and 9-10 0 at Bolton bridge at 3 p.m. the same day. On a 
previous occasion in Nidderdale, during settled fine weather, 
How Stean beck showed 1-2 0 , Ravensgill beck 3 0 , The Nidd 
at Birstwith 3 0 , at Plompton 5-6°, at Cowthorpe 6-7°. 
The disturbed state of the beds of the streams draining the 
north slopes of Buckden Pike arrested attention ; rocks had 
been recently displaced on an unusually large scale, swept 
clear of aquatic vegetation, and in several places trees appeared 
to have been shifted bodily to midstream. A similar state of 
things was seen in Bouther Gill, Wharfedale, where the 
small beck had washed out its bed ; the bridge carrying the 
Hubberholme-Oughtershaw road over it was blocked to within 
three feet of the crown of the arch ; debris containing large 
boulders was thrown across the main river, and a bank of 
gravel estimated at 60 yards in length had been laid down on 
the right bank of the Wharfe, from which the West Riding 
County Council had removed a considerable weight of material 
into the adjoining field. It seemed probable that Buckden 
Pike was in the direct course of the May 21st storm which 
left its mark on the roads for many miles round.
