WHITE WOOLLY CURRANT SCALE.

and liad done no harm to the plants. I can hear witness to these 
Currants being magnificent specimens, the berries numerous and large, 
and excellently tasted. It would have been difficult to find better 
examples of good growth. Both Red and White Currants were sent. 
The following memorandum from Mr. J. Sim (Market Gardener, 
Stonehaven, Kincardine) gives the date of his first observation of the 
Scale in that neighbourhood:—... If I understand it aright, the 
enemy is not new to our country, although the knowledge of it may be. 
Six years ago I observed a bush of the Flowering Currant, Pdbes san- 
guineum , looking very sickly, and, on examining, I found the under side 
of the branches all covered with the cottony mass you mention (which 
I took to be a fungus), but, on examining, saw it was connected with 
animal life. The bush died the following season. I do not know if it 
has spread further about Aberdeen or not. Two years ago I observed 
it on Red Currant-bushes nailed to the wall in a little garden in 
Stonehaven; a part of the wood was dead, which I cut out; the rest 
of the bush is mostly covered with it now. There are Black Currant- 
bushes which it has not touched.”—J. S. Specimens were sent 
accompanying. 
I had also information sent me from Edinburgh on July 10th, 
with specimens accompanying, of the presence of the P. ribesicB on Red 
and White Currant-bushes in a garden in Leamington Terrace. In 
this instance the infestation had been first observed in the beginning 
of June, 1889, and as the writer mentioned not having been able to 
procure any information on the subject, it is presumable that the 
attack was not at least noticeably present in the neighbourhood. 
On July 27th a branch of Red Currant infested by this same 
White Woolly Scale was forwarded to me from Arbroath. In this 
instance the infestation was slight, and the sender observed that he 
only found the P. ribesice on plants not fully exposed to the light and 
air, but he was informed by others in Arbroath that the whole of their 
bushes had been attacked. 
On August 23rd specimens were also sent of this same attack by 
Mr. F. W. Norman, of Cheviot House, Berwick-on-Tweed, who a few 
days later visited the garden from which they were forwarded, and 
wrote me that he found the whole of the Currant-trees in the garden, 
Red, White, and Black, infested, and many of them thickly studded 
with the woolly nest of the Scale-insect. The garden was very near 
the sea, and it was stated that the attack first appeared five years ago, 
but, as far as the owner knew (or could then be learnt), it had not 
appeared in any other garden. 
Washing the branches carefully with soap-suds had been tried, but 
(as noted previously, with regard to soft-soap wash, at p. 46) without 
permanent benefit.
