106 MILL MOTH. 
quarter grown ranging about in search of shelter, and shortly after as 
many as seven; these, together with the number of live moths, 
showing that the infestation was still, at the distance of six months 
and a week from receipt of the felted-up flour, multiplying to an 
appreciable extent, and at the end of May, when the specimen was 
exhibited at the show of the Bath and West of England Society, 
moths were still appearing. 
The above observation seems to me to be of some practical interest, 
as showing the capacity of the caterpillars for living on and multiply- 
ing, when developed to moth state, for a time (at least), amounting to 
very nearly a period of eight months, where small collections of flour 
or meal are left undisturbed for them to breed in. 
This shows the truth of the observations of some of our best 
millers, that scrupulous cleanliness is one method for keeping the 
infestation in some sort of check; and also gives a hint that it would 
be desirable to see what sort of state the bins or neglected corners and 
crannies of flour or meal stores of the bakers with whom the millers 
deal may be in. 
In my own inyestigations 1 have found the presence of these moths 
in such localities as the above treated as quite unimportant, and thus, 
in transit to and fro of infested flour and sacks, the pest is constantly 
being spread, where moderate care in various quite obvious ways, and 
especially baking or disinfecting the sacks, would be all that was 
requisite remedially. 
The infestation is chiefly noticed in connection with wheat flour, 
and occurs in the coarser form known as meal, also sometimes to a 
very injurious extent in biscuits. It has also been found in rice-cones.*
