so forth. On the other hand, they are easily checked. 
Bran, poisoned with Paris green and sweetened with 
molasses, syrup, or sugar and water, has an irresistible 
attraction for them. Mix 5 pounds of sugar, dissolved in 
water, and 1 pound of Paris green in 40 pounds of bran, 
and stir until it will just stick together in lumps. Then 
place a tablespoonful near each plant attacked, and 
relief will come very speedily. Poultry must be kept 
away from this; if they eat it, they, too, will be poisoned. 
Funeorw Diszases.—The principal diseases of this kind 
that attack apples in the interior of British Columbia 
are scab and peach-leaf curl. Both can be controlled 
by using the Bordeaux mixture (bluestone and lime). 
OrHER DisEases.—Under this heading we may group 
Baldwin spot, water core, and anthracnose or canker. 
Baldwin spot, or dry rot, is that disease in which little 
round depressions of a deeper colour than the apple 
generally appear in the skin just about the time the 
fruit is ripening. Their specific cause is not known, 
but they may be kept in check by proper cultivation 
and regulation of the crop. Spraying has no effect. The 
same remarks apply to water core, or the waxy, watery 
appearance which the core presents sometimes, especially 
in certain earlier varieties, such as Red Astrakhan and 
Ribston, and in Jonathan if left on the tree too long 
after it is fully ripe. Some authorities state that water 
core only comes when the fruit is not gathered soon 
enough. 
Anthracnose, or canker, is closely allied to sun-scald, 
which appears when, owing to faulty nutrition or some 
interference with the flow of the sap, the sun scalds the
