5. Rose-Bugs Killed in Air-Slacked Lime.— Air-slacked limt 

 S. M. P. in the Rural New Yorker, says will kill rose-bugs on grape-vines, 

 blown on in tbe same way as the pyrethrum powder; then why not kill them 

 when at home, on the rose? I know it must,, if applied thoroughly to reach 

 them all. I should, however not want the lime to lose its strength by very 

 long standing before using If, however, put on too freely, it may turn the 

 leaves yellow, which is the only objection to its use. 



6. Insecticide, or Insects on Plants, to Ball with the Juice 

 of the Tomato Plant. — A writer in the Dmtsche-Zeitung states that he had 

 an opportunity of trying a remedy for destroying green fly and other insects 

 which infest plants. It was not his own discovery, but he found it among 

 other receipts in some provincial paper. The stems and leaves of the tomato 

 are well boiled in hot water, and when the liquor is cold it is syringed over the 

 plants attacked by insects. It destroys black or green fly, caterjiillars, etc. : 

 and it leaves behind a peculiar odor which prevents insects from coming again 

 for a time. He states that he found this remedy more effectual than fumigat- 

 ing, washing, etc. Through neglect a house of cameUas had become almost 

 hopelessly infested with black lice, but two syringings with tomato plant 

 decoction thoroughly cleansed them. — Gardeners' Chronicle. 



7. Insects on Hot-House Plants, as Destroyed in Paris. 

 Prance. — Baron Rothschild's gardener, at Paris, France, says he destroys all 

 tlie troublesome insects that may be in the hot-house, by vaporizing 2 qts. of 

 tobacco juice in the hot-house; and he considers the remedy infallible, and also 

 says it rarely injures the tenderest plants. 



Remarks. — He does not give the strength, but I should say 4 ozs. of tobacco 

 would be plenty for the 2 qts. of the juice, as he calls it; and I should expect 

 the doors ought to be closed also while being done. The vaporizing being done 

 by setting the dish over a charcoal fire, on the plan of a tinman's heater used 

 for heating his soldering irons. 



7. Bugs on Squash and Cucumber Vines, To Destroy with 

 Saltpeter, — The following appeared in the Southern Husbandman: ''To 

 destroy bugs on squashes and cucumber vines, dissolve a table-spoonful of salt- 

 peter in a pail of water, put a pint of this around each hill, shaping the earth so 

 that it will not spread much, and the thing is done. The more saltpeter, if you 

 can afford it— it is good for vegetable but death to animal life. The bugs bur- 

 row in the earth at night and fail to rise in the morning. It is also good to kill 

 grub in peach trees — only use twice as much, say a quart to each tree. There 

 was not a yellow or blistered leaf on 12 or 15 trees to which it was applied last 

 season. No danger of killing any vegetable with it. A concentrated solution 

 applied to beans makes them grow wonderfully." 



Remarks. — This same thing has been recommended also by the Wisconsin 

 State Journal, and I have seen an inquiry about the proportion to use, in another 

 paper, which answered 1 tea-spoonful to 1 gallon of water, or 1 table-spoonful 

 to a pail. I do not believe that a J^ lb. to a pail of water would hurt the plants, 

 as saltpeter is nitre, and this is naturally in the soil and is brought to the surface 

 Jjy shading the soU with clover or even with a board.
