The conclusions to be drawn may be summarised as follows : — 
(1.) The unexpected delay in the appearance of the chemicals 
at the outlets has been due to a quiescent waterflow, and 
their appearance has usually succeeded a comparatively heavy 
rainfall. 
(2.) Under conditions of summer flow such as prevailed on 
June 22nd : — 
(a) The water descending at the Smelt Mill Sink 
emerges at Malham Cove and not at Aire Head, Gordale 
Beck, or Scale Gill Spring. 
(b) The Sinks below Malham Tarn are connected w^ith 
Aire Head and not with Gordale Beck ; and under certain 
conditions, as detailed in the report, some of the ammonium 
sulphate put in at the Tarn Sinks emerges at the Cove. 
(3.) The Tranlands Beck Water Sink is connected with 
Scale Gill Spring and not with Aire Head. 
(4.) The Gordale Beck during the very exceptional drought 
of the present year (1899) disappeared in the stream bed about 
a quarter of a mile above the Scar Waterfall and reappeared 
at the springs between Gordale Waterfall and Laithe Bridge.
