The most important are preventive measures in dealing with 
this potato pest. See that the seed is free from grub or eggs. 
Always destroy all grubs in infested potatoes, and burn all haulms 
as soon as possible after the crop is dug. Never leave “wormy 
potatoes” lying about. 
At the Hamel State Farm, Mr. F. Berthoud dusts his stored 
seed potatoes with sulphur, hydrated lime with a little Paris green 
added. 
L. J. Newman, Government Entomologist, recommends fumi- 
gating stored potatoes at once with carbon bisulphide, 2lbs. per 
1,000 cubie feet of space, for 48 hours, repeating the treatment 
again six to eight days later when the eggs have hatched. An air- 
tight fumigating tent made of a wooden fromwork 10ft. x 10ft. x 
10ft., or 1,000 eubie feet, will accommodate 120 to 150 bags of 
potatoes. Over this framework fasten tough canvas or hessian 
painted with a whitewash and covered with tarred paper or sized 
paper. Soil is thrown up around the base. A more permanent 
moth-proof room with fly-proof wire door and window may be put 
up where potato growing forms part of the farm operations. 
Tue Rep Mire (Bryobia pratensis, Garman). 
From April to early summer a reddish tint wil] be frequently 
noticed upon the bark of both apple and pear trees, but chiefly the 
latter; sometimes, when the trees are badly infested, even the stakes 
are thickly covered. Upon examination with a lens, it will be found 
that this is caused by countless numbers of tiny, round, crimson 
eggs, clustered together in every curve or irregularity in the bark. 
Later on, when the buds burst out into leaf, these little 
creatures hatch, leaving an empty white shell behind, attack the 
leaves from the underside, sucking up the juice of the tree, and 
causing them to become mottled and fall off prematurely. 
This mite is about twice the size of the “red spider,’ of a bright 
red colour, with four pairs of legs, the front pair much longer 
than the hind ones. 
Heavy rains seem to destroy great numbers, and though this 
pest is so comnion and numerous in many orchards in some parts of 
the State, it does not seem to make much headway or do much 
damage in this country, yet in some parts of America it is looked 
upon as very destructive to fruit trees. 
Remedy.—Clean cultivation. In winter, dress limbs with No. 
6; later on, 15 or powdered sulphur. Two or three dressings dur- 
ing spring and early summer. The sulphuring is best done early 
in the morning if applied dry, being then less inconvenient to the
