 ciple might be usefully applied with us in " patching." 



In the coming season it would he very desirable to have more observations, 

 to enable us to identiftj what attack, or attacks, are jn-evalent at young 

 Mangold roots. We know that Atomaria attack was found at Cirencester, 

 and attack resembling it elsewhere, but other infestations may be present. 

 If observers ivould kindly send specimens to myself, 1 would do my best to 

 investigate thoroughly.

 affecting districts, in Cornwall, Devon, and Hants ; more inland, in 

 Warwickshire, Berks, Bucks, Herts, and Surrey ; in Bedfordshire and 

 in Essex, there was also presence of the infestation, and enquiry 

 regarding it was also sent from Norfolk. It may be presumed that the 

 infestation was present at many other localities besides those from 

 which enquiries were sent, but still these give some idea of its 

 prevalence. 



The date of the first series of enquiries ranged from May 31st to 

 June 20th. From the specimens sent, and observations accompanying, 

 the attack appears to have begun in some cases as soon as the young
