STICKY-BANDING. 89 
yet still so much moth presence may be conveyed to the trees by 
methods which evade the barring out of the sticky banding, that this 
method cannot be wholly trusted to as a preventive, even in the most 
careful hands,—even where, as in this case, the moths were found to 
be captured in due course by the bands. Messrs. German wrote 
as follows :— 
“As promised, we have much pleasure in sending you a detailed 
report of our operations with regard to the attack on the Lime-trees 
of the moth of the Cheimatobia brumata. On October 5th, 7th, and 
8th, sticky bands were put on the trees. . . . Bands renewed 
November 6th and 7th, owing to wind and rain having rendered 
them useless, and again renewed from November 13th to 20th. On 
November 27th Morris & Little’s antipest was applied round some of 
the trees on the ground, and on the same date a dressing of freshly 
slaked lime was applied round others. Fresh sticky bands were put 
on some of the trees to ascertain if moths ascended after the above 
applications. Although the earth near the tree trunks was literally 
alive with moths at the time of the above applications, scarcely any 
moths were seen to ascend after the dressing of lime, whereas more 
were noticed on the trees around which the antipest was used. 
‘‘On December 11th lime was applied to remainder of trees in 
avenue, and bands were put on six trees to indicate when the moths 
again commenced their ascent. 
‘On March 5th and 6th all old papers were taken off, the trunks 
of trees were scrubbed with warm water, and sticky bands were re- 
newed on all the trees in the avenue. Very few insects were caught. 
“On April 14th and 15th the bands were taken off, and the trunks 
washed down with paraffin and water. 
‘‘The avenue trees were attacked again to a considerable extent, 
which is rather disappointing, although, of course, we did not expect 
to cure so extensive an attack in one year. 
‘“‘Tt was noticed a few days ago, after a windy night, that many 
caterpillars were crawling up the trunks of the trees. They were, we 
suppose, thrown off by the wind, and were again ascending. We think 
the trees were benefited by the dressing of lime, and that the attack 
is not quite so bad as last year.” —(J. G. & Son.) 
The above record, it will be seen, gives full details of most careful 
operations. We have, to start with, the kind of tree attacked, and 
the kind of moth caterpillar, namely, the common Winter Moth, 
Cheimatobia brumata, and I may add that I had myself for a long time 
been, at intervals, in correspondence with Messrs. German regarding 
this attack. It will be seen that the ‘‘sticky-banding”’ was first 
applied even before the date which is thought absolutely necessary. 
On October 5th and following days bands were first applied; on
