The larvae of this fly are said to have seriously injured young 

 wheat in England by feeding in the stem. The damage caused 

 seems to have been generally attributed to wireworms. 



Leather Jackets. The Journal of Board of Agriculture, De-

" The Board of Agriculture and Fisheries are informed that the 

 Lancashire Farmers' Association are taking steps to induce their 

 members to adopt cultural methods for reducing the numbers of 

 the larvae or grubs of Daddy long-legs, or Crane Fly, and the 

 Board desire to bring this information to the notice of all farmers 

 in the north-west and north of England and the south-west of 

 Scotland, in which districts these grubs, known as Leather Jackets, 

 have wrought great injury in recent years, more especially to the 

 oat crop. 



" The methods recommended are as follows : Clover leys 

 which are to be sown with cereals to be closely cropped and a 

 dressing of gas lime applied. The land to be skimmed and the 

 cultivator used several times, so that the grubs not destroyed by 

 the lime will be brought to the surface and picked up by birds. 

 The autumn sown land to be well harrowed and well rolled with 

 the Cambridge roller in spring, and a dressing of one or two cwt. 

 of nitrate of soda applied per acre. A leaflet on the subject can 

 also be obtained from the Board of Agriculture, London, free on 

 application."

It is stated that the hop is not subject to the attack of very 

 many insects and allied creatures. Forty-two species only of true 

 insects or hexapods have been found feeding on the hop in Britain, 

 but of these only seven are reported of any general importance, 

 namely three wireworms (Elateridae: Agriotes lineatus L., A. sputator 

 L., A. obscurus L.); the hop aphis (Phorodon Humuli, Schuk), by
