Special Meetinrj and Fldd Excursion at Malham, June 21st 
and 22nd, 1899, under the direction of the Underground Waters' 
Committee. 
After dinner at the Buck Hotel, Malham, on June 21st, 
Mr. Walter Morrison, M.P., in the chair, it w^as decided to put 
common salt into the Smelt Mills sink, and ammonium sulphate 
in the upper Tarn sink. The How of water from the Tarn w^as 
to be regulated to a normal amount, but at one o'clock p.m. 
an increased volume of water was to be sent down. Arrange- 
ments were made for the putting in of the chemicals, for the 
watching of the outlets at the Co^'e and Aire Head, and for 
the working of a central testing station at the Buck Hotel. 
On Thursday, June 22nd, these arrangements were carried 
out, but up to the morning of June 23rd, when the Committee 
left Malham, there was no trace of chlorine beyond the normal, 
and no variation in the ammonia was detected, either at the 
Cove or Aire Head. 
One pound of fluorescein w^as also put into Tranlands Beck, 
the lower part of which was dry. Xo change was found either 
in the main stream or at Aire Head springs, but the next day 
the fluorescein was found to issue at a spring at Scalegill Mill, 
about half a mile to the south. 
Before leaving the Committee arranged for more salt to be 
introduced into the Smelt Mill sink, and for a series of samples
