to a badly infested hop garden and allowing them to tread down 

 the ground thoroughly. 



Forest tree pests. Many applications for advice have had refe- 

 rence to forest-tree pests, including larch-bug. Lithocolletis on Holm 

 oak (Quercus flex), Pemphigus bursarius on poplars, a saw-fly (Ten- 

 thredinidae] on hawthorn, and a leaf miner (Phytomyza Ilicis) on 

 holly. Wintermoth (Cheimatobia brunatd] on ornamental trees, and 

 very frequently the beech-scale (Cryptococcus Fagi}. An ordinary 

 paraffin emulsion was generally effective against this pest and the 

 wash advocated by Mr. Gillanders proved very efficacious. It is com- 

 posed of half a gallon (2 litres) of soft water, i Ib. (kg. 0,454) of 

 soft soap, i Ib. of common soap, a handful of sulphur, i pint (57 

 centilitres) of paraffin and about the same quantity of turpentine. 

 It is applied with a brush about May when the larvae are hatch- 

 ing out. 



Fruit pests. The inquiries relating to fruit pests did not pre- 

 sent any features of especial interest. 



The list comprised many aphis attacks, some cases of "big- 

 bud," pear leaf blister mite, saw-flies, goat moth (Cossus) and the 

 fruit-tree bark beetle (Scolytus rugulosus) and a few of "red-spider" 

 (Hryobia). 



Parasitic diseases of animals. Cases were reported of the following: 

 "Gapes" (Syngamus trachealis] in pheasants. Intetsinal worm 

 (Sclerostomum bypostomuni] in sheep, and warble-fly (Oestridae). 



Besides these several creatures living in water were sent for 

 identification. In most cases they were innocuous, among these 

 may be mentioned the "Hair worm" (Gordius). 



Miscellanea. It is not so generally known as it should be that 

 the wasp-grubs are exclusively reared on insect lood. Taking the 

 whole life of a wasp, far more insects are devoured than fruit foods 

 and if it should prove that most of the insects fed to the grubs 

 were injurious, it would follow that wasps do a considerable amount 

 of good. 



The A. examined many worker wasps holding insects in their 

 jaws and never found a useful insect as prey, but in the majority 

 of cases they were positively injurious.
