CASSELL'S POPULAE GAEDEXING. 



or hrnising the shoots. The hrush is then drawn up- 

 wards on the line of growth, and the find of Aphides 

 shaken or combed out. A fresh hold is then taken, 

 and so on, till all the Eoses are cleared. 



A thorough vibration through the plant, caused by- 

 giving the tree a sudden shake or tap, wiU make all 

 the fullest, fattest Aphides faU to the ground. This 

 should always follow the above. Any left after these 

 processes are mostly on the move, and a sudden shake 

 or vibration will bring most of them to the ground. 

 When once there they seldom succeed in returning. 

 However, some, to make assurance doubly secure, 

 provide an adhesive bed for them to fall upon. The 

 most killing bed is formed of one and a half parts of 

 Burgundy pitch, and one of train oil. The pitch is 

 slowly melted, and when dissolved the oil is added. 



soft soap, and quassia cUps, are among the most 

 potent of Aphides-Mllers. 



A capital Uquid dressing may he made of a pound 

 of good tobacco, and half a pound of quaasia chips, 

 Giflhurst compound, or soft soap, the whole being 

 carefully dissolved in boiling water, or boUed for a 

 quarter of an hour in sufficient water to dissolve and 

 incorporate it thoroughly. Then run it through a 

 sieve and add to this powerful decoction from twelve 

 to fifteen gaUons of water, and apply the mixture 

 carefully to the Aphides, or dip the branchlets into

and thoroughly mixed, and this mixture continues 

 liquid and sticky to a fault. A thin board, or 

 cardboard, or thick paper, smeared over with this, 

 and held under Eose-trees by a simple loop, with 

 a slit in one side for the stem of the Eose, and a 

 hook to hold by, will give account of any Aphis or 

 caterpillar that drops down on it. 



Tobacco -smoke, either pure or produced from 

 paper, rags, or refuse dipped into tobacco-water or 

 juice, proves sudden death to all kinds of Aphides, 

 either out of doors or in, if the smother of smoke is 

 only made and kept sufficiently dense for, say, ten 

 minutes. A smoke-proof bag, to hold the heads of 

 standard or other Eoses, should be tied closely roimd 

 the stems. Apply a blow-pipe of sufficient force to 

 fill it and keep it full for the above length of time, 

 and every living Aphis will be cleared oft. 



To mate security doubly sure, so soon as the bag 

 is removed dash water through the garden engine 

 over the entire smoked plant or buds. This com- 

 pletes the work of clearance by dashing any sick 

 Aphides to the ground, to rise no more. 



Tobacco, in dust, as snufE, or solution as tobacco- 

 juice or water, either pure or in combination with 



the mixture. It will instantly kill all it touches. 

 Such powerful dressings should never, however, be 

 applied during the heat of the day, but in the after- 

 noon or evening, be left on all night and washed off 

 in the morning. 



Snuff, the iinest-ground and driest that can be 

 bought, should be dredged on while the shoots are 

 wet. The Aphides fall down on the heels of the 

 dredging, dead. Common and cayenne pepper are 

 generally effective, but though they hardly smeU 

 so vilely among Eoses as tobacco in any of its forms, 

 yet their presence is about equally objectionable and 

 even more dangerous. 



Carbonate of ammonia, or smelling salts, dissolved 

 in water at the rate of an ounce to a gallon, proves 

 most destructive to Aphides, leaves a pleasant odour 

 behind it, and proves, so it is said, a stimulating diet 

 for the Eoses into the bargain. 



Rose Maggots. — Eose-growers are all too 

 familiar with the worm in the bud that wrecks so 

 many of their best blooms, though the moment 

 we try to determine which worm, we are met with 

 considerable difficulty, not from any lack of worms.
