Readers are advised to cut out and 

 preserve the article on exterminating the 

 white fly with hydrocyanic acid gas, 

 which appears on this page. In spite of 

 the fact that the formula has been pub- 

 lished scores of times, almost daily 

 requests are received for it.

HYDEOGYANIC ACID GAS. 



Inclosed in separate cover I send you 

 a lettuce leaf, infested with a white in- 

 sect, which causes me no end of troujjle 

 and loss. The most frequent fumigations 

 with tobacco do not seem to affect it. 

 Last season I tried hydrocyanic acid gas 

 according to your specifications. It 

 helped only temporarily and it injured 

 the lettuce to quite an extent. I fumi- 

 gated in summer with sulphur, but, alas, 

 the insect is again at work I It does not 

 seem to hurt the lettuce until nearly 

 ready for sale, when it commences to 

 spread rapidly upward, causing the edges 

 of leaves to decay. Spraying at this 

 stage is almost out of the question. 

 Would arsenic be of any use, and in 

 what form? Or could I use hydrocyanic 

 acid gas in a mild dose and let it stand 

 all night? O. E. P. 



The little white insect is the white 

 fly, which has now become a great nui- 

 sance all over the country. There is 

 but one sure remedy when once these 

 pests appear in an establishment. Pre- 

 pare to battle with them at once and 

 keep prepared for their return. Cyanide 

 is the only kind of fumigating material 

 which will affect them in the least. "We 

 have tried every known insecticide, but 

 nothing else will harm them. 



Cyanide is not as expensive to use as 

 most other insecticides, and when prop- 

 erly used it will not injure plants in the 

 least and yet will be strong enough to 

 exterminate all insect pests and keep 

 your houses clean of them. Any green- 

 house proprietor not experienced in the 

 use of this valuable exterminator should 

 learn at once and educate his employees 

 in its use. There are some facts abo\it 

 the use of hydrocyanic acid gas which 

 have not been published, and through 

 lack of knowledge or experience many 

 growers give up using it after the first 

 unsuccessful attempt. In fact, most men 

 are only too glad to stop using it, oYi 

 account of the danger, the gas being as 

 deadly to human beings and animals as 

 it is to insects. There is, however, 

 nothing to fear if the fumigating is done 

 by careful men who know what they are 

 doing, and all doors are securely locked 

 for the night, so that no one gets inside 

 until morning. Heating pipes should be 

 set for the night. 



Cyanide of potassium is worth about 

 50 cents per pound and sulphuric acid 

 about 50 cents per gallon; that is, in 

 quantity and at whoFesale prices. But 

 the best way to get it in smaller quan-

titles is to have your druggist put up 

 the cyanide in 2^-ounce packages, se- 

 curely wrapped in two thicknesses of 

 paper. The acid you can buy by the 

 jug, and the half-gallon stone jars in 

 which to mix it cost only a few cents 

 and can be used for years. When you 

 have these materials you are ready for 

 business. A still night should be chosen, 

 when there is little or no wind. Place 

 the little jars in the aisles, as closely 

 as needed. Then take a pail of water 

 and a dipper holding exactly a pint and 

 put a pint of the water in each jar. Do 

 not put in the acid until you are about 

 ready to drop the packages, as it seems 

 to weaken very rapidly after it is di- 

 luted with water. 



Now see that all ventilators are shut 

 and all doors locked except those at one 

 end of the houses, which you are to 

 use in getting out. Also see that no pet 

 animals are left inside, and if you have 

 vegetable houses with bees in them, carry 

 the swarms out also. Now take the sul- 

 phuric acid into the houses in a pail, 

 just as you did with tlie water, and put 

 just a pint in each jar, also taking care 

 that your cyanide is not near until you 

 are ready for it; keep it locked up until 

 the last moment. You now have a pint 

 of water and a pint of acid in each jar. 

 The acid will sputter a little when it 

 mixes, but is not dangerous unless you 

 spill or spatter it upon yourself. 



You are now ready for the last act. 

 Take your packages in small tins or 

 baskets, as many basKets as you have 

 rows of jars. Let one man take a basket 

 to the far end of each row of jars; all 

 drop in the first packages at the same 

 time, then go to the next jars and so on 

 until you get to the end of the house 

 and out at the end door, locking it 

 without delay. 



It is best to have a door-tender, so as 

 to have no trouble in getting out. Do 

 not unwrap the packages, but drop them 

 in with the paper securely wrapped 

 around them. Do not let the acid spat-

ter on your hands when you place the 

 package in the jar. Above all things, 

 do not go back past the jara after you 

 have placed the packages in them. 



It is safe to go into the houses in the 

 morning and open the ventilators a lit- 

 tle, although you can usually smell the 

 gas very faintly. Do not stay in long 

 until the houses air out a trifle; then go 

 back and spray the plants. Plants should 

 not be too dry when fumigated, but 

 spraying before fumigating is unneces- 

 sary. 



For houses thirty feet wide, six such 

 jars per 100 feet of house will kill all 

 the white flies. This might be too strong 

 for some plants and five jars might be 

 enough.
