 The first time- we tiied it we used llowor 

 pots with tlic di'aina^e hole idujj;ged with 

 a. I'ork and cdNO'ed witli a little coincMit. 

 I stood in the door of the yreenhouse and 

 noted that the nimnent the arid ate 

 through the tissue jiajuM' wrapped arouiul 

 tlie cyanide the liquid boiled violently 

 and overllowcd the jxit. How large a 

 reccptaele should be used and is there 

 a loss if the liquid boils over? 1 have 

 since been told that I was exceedingly 

 careless standing in the greenhouse door 

 and watching the operation. IIow quick- 

 ly is the gas generated and how rapidly 

 does it spread? Js it heavier or lighter 

 than the atniosjdiere? In other words, 

 would a man who felt himself being 

 overcome with the gas save himself by 

 dropping to the tloiir? ]\. G, 



Our experience has sliown that hydro- 

 cyanic acid gas is not a good insecticide 

 for rose houses. It does not kill thrips 

 readily and is very injurious to the 

 young growth on roses. 



The ^as, \\liih' only a little lighter 

 than air, s]ii( ads (juite rapidly through 

 a ;4reen Ik iu.se. A house lltO feet long 

 and t\\('l\(' feet wide, walls three feet, 

 seM'U feet te the ridge, with three jars 

 would be tilled with gas in about two 

 minutes. Sueh a house would rcMunre, 

 say for \ inlets, about two pounds n\ 

 ninety-eii;hl per cent eyaiude of potash. 

 Tills would be ili\ided into three jiarts, 

 each pDiticm |nit in a 2-])ound light ma 

 nila jiaper sack. Starting at one end. 

 these sack.s can l)e jdaced in tl'.e .jars 

 containing the sul|)hniic acid and water, 

 and the lenL;j]i of time reipiired for the 

 acid to eat through tlie paper would 

 •j,\\v the operator suflicieut time to get 

 to the others and out of the house safely. 

 The acid will eat through cork, so that 

 the tlower-pot with the drainage hide 

 jdugged Avitli cork would not be a good 

 vessel to liberate the gas. 



The corres])ondent can obtain full in- 

 formation regarding the use of hydro- 

 cyanic acid by writing the Department 

 of Agriculture. AVashington, I). C, and 

 requesting C'ircular Mo. .'57 (revised edi- 

 tion) of the Division of J-'idomology. 



Nicotine Preparations. 



For tlni])S in rose houses fairly good 

 result.s caii lie obtained by va])orizing the 

 stronger nicotine preparations, either 

 over single-l)nrner oil-stoves or by drop- 

 ping into the solution pieces of hot iron. 

 A good-sizctl hot tlat-iron, for example, 

 will vaporize about a pint of nicotine 

 extract. I'^or a rose house ]00 feet long, 

 eighteen feet wide and ten feet high 

 to the ridge, a pint ami a half to two 

 pints of a good nicotine tract vaporized 

 at intervals of a few dnys will usually 

 tlestroy thrips. 



If the stronger extracts are to be 

 painted on the pipe.s, the work should 

 be dom^ when the pipes are cool. If 

 steam is used in heating the houses the

A good Avay, where ihe .strdiiger e.\ 

 tracts are used, is to have a number m 

 vaporizing tanivs lit lid over the steaii* 

 ])ipes or rather attached id the ])iiies s^ 

 that the pi|)es will run ihrdugh tlioiii 

 having from three to ti\e ol' these va 

 ))oriziug troughs in a house lUO feet 

 long and eighteen feet wide. The ui'-o 

 tine solution can then be poured into tin 

 vaporizing troughs, and the hot ]ii)ie- 

 will throw it into the atmosphere. 



Various other methods of vajioriziiij.' 

 are used, but these suggestions will prob

" WITH THE GROWERS.

<)ni> of th(.' largest e^t.-dilishments \n

 iV I'd., at Auburn, near I'rovideiice, K. J. 

 Fntil a little o\er thne years ago the 

 iinn -was noted a^ diie df the biggest 

 ])rodiicers of vegei.ables fer the market, 

 ])i(kling varieties being their specialty. 

 These tiiey still grow rui an immense 

 scale, Inning some ].")Oo acres under 

 cultivation, but whereas a few A^ears ago 

 several mile.s of sashes were devoted 

 to lettuce culture, this luancli has been 

 reduced somewhat and all greenhouses 

 are given up to cut llower production 

 with the exception df one large structure 

 from which a crop of rhubarb is taken 

 1o lie followed by lldwers in early spring. 

 Between the vegetable farms, pickle and 

 \inegar factories and grei'uhouses an 

 army of Gnu to 70n men and women are 

 on the i)ay rolls at tlie iieight of the 

 busy season. 



Although so t^hdri a tiine> has elapsed 

 since the firm launched into the cut 

 llowei' business, they ha\f built up one 

 of the finest plants in the country. Sev- 

 eral of the long, rathi'r low lettuce 

 houses are given up to carnation culture, 

 the roses occupying the newer ones, these 

 latter being of the nidst up-to-date types. 

 'J'iie largest house. CiO.xTou. is one of the 

 finest in the country. It contains nearly 

 ]!>,()0n Brides and Bridesmaids. One 

 house is 40x7l»0 and two others 22x70n. 

 'J'here are two 4ox}.'d. mie 40x412 and 

 se\('ial of sniallei si/e. In regard to \a- 

 rieties, I'.rides and .Maids to the number 

 of fiO.onO are ]ilanted. tlie latter having
