following year, 1865, the attack was not nearly so bad. We tried no 
remedy, but the rooks and insect-eating birds eagerly devoured the 
grubs wherever they found them.” 
In the case of turf infested by Cockchafers, Mr. James Forrester, 
Bryanston, Blandford, notes rolling as a useful application, as well as 
encouragement of rooks. He observes—“A large lawn of old turf 
became the haunt of rooks in April, but were scared, and the turf was 
soon yellow and nearly dead. On examination the Cockchafer Beetle 
was found to swarm, but by heavy rolling the turf was saved. Since 
that year the rooks have their full feast on the lawn in the spring, and 
it is evident that they clear the beetles, as the turf has been perfectly 
preserved. 
In the ‘ Transactions ’ of the Entomological Society of Ontario, 
1881, mention is made of moles proving very useful in clearing grubs 
of one of the Canadian Chafers, Lachnosterna fusca, from a piece of 
badly-infested Potato ground broken up from turf. Many of the 
Potatoes had been partly eaten by the grubs, but wherever a mole-run 
traversed a hill of Potatoes no grub was to be found, even though the 
half-eaten Potatoes were proof of his former presence. 
Where the ground is without crop turning on pigs to follow the 
plough is a good plan, but it does not appear practicable at present 
to get rid of the grubs in occupied land by any dressing that will not 
hurt the crop. I have tried the Paris Green (experimentally) without 
finding any effect. 
Where the ground is not occupied (and the materials are pro¬ 
curable) very heavy dressing with gas-lime in its fresh caustic state, 
or “chemical waste,” which can be procured at little more than 
expense of carriage from alkali works, would be very desirable appli¬ 
cations. The applications are equally destructive to everything they 
touch at first, and good manure, where gypsum is serviceable after¬ 
wards ; but the fact of the “ waste ” being procurable for carting near 
the works has caused it to be much used in some localities as a 
destroyer of plant vermin and weeds. 
Pine-bud Tortrix Moth. Retinia turionana, Hubn. 
On the 15th of April Mr. Coupar forwarded to me some twigs of 
Scotch Pine, Pinus sylvestris , taken from a plantation nine or ten 
years old, with the note that the insect of which this contained pupae 
did much harm in young Scotch Fir woods. 
On examination I found that the shoots, or rather sprouting buds, 
were more or less coated at the base with turpentine, which flowed 
from the injuries caused by the caterpillar. In some instances most 
of the buds had perished, and the end of the shoot become little more
