Mr. St< \rii-. — As a rule, plum rot is caused by some air germ; 

 but there may be some soil germ. Spraying with the Bordeaux 

 mixture, when done before the buds open, tends to prevent the air 

 g( nil from working. 



Question. — What will kill lice on black raspberry bushes? 



Mr. Smith. — An emulsion of whale oil soap is as good as any- 

 thing I know. One pound of soap dissolved in four gallons of 

 water, sprayed on. Do it when the first signs of the lice appear. 



Question. — Is arsenate of lime as effectual as are insecticides 

 or Paris green? 



Mr. Woodward. — Green arsenoid or arsenic of lime or of soda 

 are preferable to Paris green. White arsenic and common washing 

 soda is much better than the green. Mix one pound of white ar- 

 senic with two pounds of washing soda in one gallon of water and 

 boil it 15 minutes, which will make a perfect mixture, and one 

 which will remain in suspension much longer than will Paris green. 



Question. — What will kill smut on seed oats, and how much 

 to use? 



Mr. Smith. — Hot water at a temperature of 132°. Below that 

 degree the smut germ will not be affected, but it is killed at that 

 figure. If the water is at a higher degree the live germ of the grain 

 will be killed. 



Question. — Will not corrosive sublimate kill the smut? 



Mr. Smith. — No; it is not used for that purpose, but is for 

 destroying the potato scab. After the oats have been soaked 10 

 minutes in the hot water, spread them out to dry. 



Question. — What is the best remedy to kill lice on cattle? 



Mr. Smith. — Anything that will stop their breathing; grease 



will do it. so will road dust. Whatever you do, do it often, as the 



- hatch rapidly, so that to get rid of the lice, one must apply the 



remedy quite often for a while. Keep up the treatment until all 



destroyed. Tobacco water will also kill them. 



A Farmer. — Give the animals all the grain thev want. If you 

 do that, there will not be many lice. 



Mr. Smith. — Once the vermin get into the stable, grain will 

 not drive them out. I have seen lice on very fleshy cattle. 



Dr. Smead. — Kerosene and lard in the winter, equal parts, 



melted. Put it on with a brush. The louse lives on the sweat of 



mimal. The calf does not sweat, neither does the poor animal. 



best to use some remedy to kill the louse quickly. The old 



dy was a mercurial one. The louse is a biter, not a sucker, 



so it must be poisoned. Washing by some of the sheep dips will
