the rain, sure to keep off the striped bug. It does not kill them, but 

 keeps them away. The black or Stinking Bug is not so easily driven 

 ■off. The only way known to the writer is to watch the insects closely,, 

 and catch and kill every black bug as soon as it appears, and carefully 

 examine the underside of every leaf, both in order to find the bug and 

 to find the eggs, which latter need only to be rubbed off and allowed' 

 to fall on the ground to perish. This is the only e-jfectual. method 

 known to the writer, and it is not as troublesome as it may seem, for" 

 the egg-laying season is soon passed, and if none of the eggs are 

 allowed to hatch there will be no bugs to destroy the vines. It is the 

 young brood that do the mischief, not the parent bugs, in the way of 

 sucking the life out of the vines. 



C. R Matthew, Clinton, writes : — 



I have a dwarf apple tree which I find this spring month with what I suppose to' 

 be sun scald. The bark on the smooth side of trunk just above the collar is Mackened, 

 split and loosened from the tree. What shall I do with it ? Had I better apply to 

 the diseased spot pine tar, or shellac, or linseed oil ; which would be best ? And if 

 applied, should the loosened bark be removed first ? 



Eemove the loose bark from the tree, and apply a thick mortar of 

 fresh cow-dung and clay ; then bank up with earth, to keep it moist. 



An esteemed correspondent writes : — 



Black-knot. — I wish you would state in the Horticulturist who are the parties 

 to apply to in order to have the act relating to Black-knot put in force. There is 

 considerable of it here, and some parties will not attend to it until compelled to do- 

 60, and I want to know the best way to get at them. 



The Statute, 42 Victoria, chapter 53, sec. 3, provides that any mu- 

 nicipal corporation in Ontario may appoint an officer or inspector for' 

 the purpose of carrying out the provisions of the act ; and if no such 

 in.spector be appointed, it shall be the duty of the Overseer of High- 

 ways, upon request of any person interested, to give notice in writing 

 to the owner or occupant to cut out and burn up the Black-knot, un- 

 less he shall be satisfied upon inspection that the disease does not 

 exist in the place complained of. If after two weeks notice the owner 

 or occupant knowingly suffers any Black-knot to remain, he shall 

 upon conviction, be liable to a fine of not less than one nor more than 

 five dollars for every such offence. The offence shall be punished and 

 the penalty recovered on conviction before any Justice of the Peace, 

 and the fines paid into the treasury of the municipality in which the 

 offence takes place.
