326 Report of the Honorary Consulting Entomologist for 1884. 
I have verified the method of mixing by personal experiment, 
and find it very simple, and shall be happy to give details to all 
applicants. 
Quassia has been acting well during the last season as an 
addition to the common soft-soap hop-washes. 
Paris green was tried at my request, and failed to have any 
effect on the hop aphides. 
A method of hop- washing by steam-power has been in- 
troduced near Tunbridge Wells, which has, as yet, only been 
tried on a limited scale. So far it is stated to be successful, 
and to have the advantage of washing a much larger acreage 
at a less cost per day than can be done by hand or horse 
engines. 
Many other communications have been sent in, of which the 
following refer to points of practical interest. 
With regard to the caterpillars of the " winter moths," which 
are exceedingly destructive to leafage of fruit-trees, the recom- 
mendation given to prevent egg-laying

the stem in December with a band of 
Davidson's composition, laid on for 
about the width of a foot. The female 
moths (which have only abortive wings) 
were thus caught by hundreds on their 
way up the trunks from the ground, and 
the trees which had been so infested for 
several years that leafage and blossom

served from attack. 
This simple remedy, if applied early in winter, would save 
much loss in fruit-growing districts. ' 
Specimens of a large kind of daddy-longlegs grub, which is to 
be found in muddy localities, were forwarded to me from the 
neighbourhood of Stroud, Gloucestershire, with inquiry as to 
their nature, they being found in the drinking-water supplied 
through pipes. The water was very foul ; and it having been 
incidentally mentioned the household were ill, and they were 
obviously unaware of their danger, I telegraphed to stop the use 
of the water, and reported the case to the health officer at Stroud, 
who inspected, and stated that the water was unfit Ifor use. It 
appeared that a cattle-pond had been made across the course of 
the supply-pipes in a neighbouring field, and thus the water was 
carried in pure on one side, and transferred foul on the other 
for household purposes. It is so eminently desirable that care
