MOSSES OF DURHAM 
(V.-C. 66, comprisinc Upper Trespaue anp Upper WEARDALE). 
By Ww. Ineuam, B.A. 
Tue Mosses in this list were gathered during three visits to 
RP in 1896, 1897, and 1899, and one visit to Weardale in 
1898. In Teesdale I examined (1) che vast amphitheatre of basaltic 
cliffs about the High Force, with the wood adjoining ; (2) ae Siyte 
range of basaltic ‘cliffs abuttin ng upon the Tees, an 
Falcon Clints; (8) the vast moorland of Widdy Bank Fall ; (4) 
Langdon Be ck. 
In Weardale I traced to their sources streams which, united, 
make the River Wear at Wearhead. ‘These streams are Burnho ope 
Burn, Sedling Burn, Kilhope Burn, Welhope Burn, and Ireshope 
Burn, the last cutting through a bed of mountain limestone, and 
been carefully e and 
uncertainty have passed through Mr. Dixon’s hands, and a few, in 
ees through Dr. Braithwaite’s. 1am very much indebted to 
Mr. Dixon for his kindness, and I wish to thank Dr. Braithwaite 
for hie help.
