62 FLOUR MILLS AND STORES. 



to roller mills and other machines uneven, and might at such a point 

 do vast injury to the plant." 



Unless the appearance of the pest in its different stages, and also 

 the peculiar felted-up state of infested flour, are hioivn, the attack 

 cannot be properly fought ; and in the foregoing paper I have 

 endeavoured to condense what appear to be the most important points 

 bearing on the subject, which have been brought forward since the 

 first appearance of this mill trouble (in this country) in 1887. Details 

 of the method of attack, and the means found of more or less service 

 in prevention, will be found in the ' Bulletin ' on the " Flour Moth," 

 bearing date Oct, 19th, 1889, and the Appendix to the same of Oct. 

 15th, 1890, issued by the Department of Agriculture, Ontario, Canada ; 

 and in my own 12th, 13th, and 14tli Annual Keports on Injurious 

 Insects, in the first of which are references to some more purely ento- 

 mological observations. 



It is well known to all suffering under the pest how much some 

 more information is needed as to remedial measures, and the above notes 

 are only given as leading points in how far we have advanced at 

 present, and also in the hope that those who know more may come 

 forward and help by additional information, which would be a great 

 public benefit. 



I should be happy to receive anything sent to myself for publication, 

 and meanwhile have had a separate impression of fifty copies of the 

 foregoing paper printed for gratuitous distribution to any applicants 

 practically interested in the subject.
