then applied as a spray. It is especially excellent for destroy- 

 ing the imported currant worm. 



Tobacco Decoction. — The use of toliacco smoke in closed 

 rooms, like forcing houses and conservatories, is too well 

 known to need remark. That a decoction is also very valu- 

 able is perhaps not so well known. For this purpose even 

 the stems or refuse powder will answer well. A pound of 

 tobacco to two or three gallons of water makes an eflective 

 decoction, and may be prepared by turning boiling water 

 on to the tobacco, and when cool strain out the tobacco, and 

 the decoction is ready for use. 



Carbolic Acid Emulsion. — This is made like kerosene 

 emulsion, only stronger. Use one part of crude carbolic 

 acid to from five to seven parts of the soap solution. It is 

 very valuable for the destroying of apple tree bark lice and 

 apple tree borers, and is easily applied. 



Bordeaux Mixture. — This is a valuable fungicide, and 

 has for some years been employed in European countries as 

 a preventive of fungous attacks on grapes. It is prepared 

 as follows : Six pounds of sulphate of copper are dissolved 

 in six gallons of hot water ; in another vessel four pounds 

 of fresh lime are slaked in six gallons of cold water. After 

 the latter solution has cooled slowly turn it into the other 

 solution and add ten gallons of water. This when all is 

 thoroughly mixed is ready for use. In using it must be 

 kept agitated to keep the precipitate formed in suspension. 

 Prof. C. M. Weed of the Ohio Experiment Station has shown 

 that when this is used to spray plum trees, the plum rot is wholly 

 kept in check. Professor Weed recommends that in spray- 

 ing for the curculio, we use this Bordeaux mixture instead of 

 water ; that is we add one pound of London purple to two 

 hundred gallons of the Bordeaux mixture. Thus we may 

 not only defend against the curculio but the rot as well. 



Professor Garman, of the Kentucky Agricultural Exper- 

 iment Station, states in Circular No. 3 of that station, 

 that from experiments conducted there, he is satisfied that it 

 is a valuable protection aaainst the injuries from o-nawinsr 

 insects, and that for injury from the striped cucumber beetle, 

 the flea beetles on turnips and potatoes, the blister beetle on 

 potatoes, and the like, nothing better can be used.
