‘“WITCHES BROOMS” ON BRITISH WILLOWS 103 
However this may be, the gall (or, rather, the insect producing it) 
aoe quickly, first over Devonshire (whence it was called at first 
‘it may be foun 
there is oak throughout the whole of Britain.” It has become, in 
fact, one of our very commonest and most widely-distributed galls. 
his remarkable invasion naturally excited during its pro- 
gress a very large amount of interest, and the literature relating to 
the matter is extensive. During its progress many people became 
apprehensive lest serious injury might be done to British oaks; 
but fortunately this fear has not been realized, in spite of the 
immense abundance of the gall. It is to be hoped, therefore, that 
the newly-introduced willow gall will prove equally harmless to 
the British willows. 
_ I am indebted to all those I have mentioned for help and 
information kindly given. Not least have I to thank Mr. Savage, 
of the Linnean Society, for the excellent photographs from which 
my illustrations have been made.
