adult can be killed easily at the time 

 of emergence by consistent spraying; 

 fifth, fumigation experiments in a com- 

 mercial house proved that the adult is 

 easily killed by fumigation either with 

 nicotine papers or hydrocyanic acid 

 gas; sixth, experiments applicable to 

 general propagation practices show con- 

 clusively that such measures offer a 

 reasonable safeguard and protection 

 against doubtful stock and infested ma- 

 terial without injury to the plants. 



For Light and Heavy Infestations. 



"In case of a light infestation, daily 

 picking of gall-infested leaves will hold 

 the pest in check. Should this prac- 

 tice prove ineffective, nightly fumiga- 

 tion for a period of two or three weeks 

 may be resorted to. 



* ' When a severe infestation is en- 

 countered the most heavily infested 

 ])lants should be taken out immediately 

 and burned. This should then be fol- 

 lowed by either fumigation or spray- 

 ing. Fumigate every night, with either 

 nicotine papers or hydrocyanic acid 

 gas, for a period of at least six weeks. 

 This will kill all the adults that emerge 

 <luring such a period and at the same 

 time prevent the further laying of eggs 

 for future generations. The dosage 

 need not be heavy in either case. When 

 nicotine papers are used one sheet to 

 every 1,000 cubic feet of space will suf- 

 fice. If hydrocyanic acid gas is em- 

 ployed, one-eighth to one-fourth ounce 

 ])er thousand cubic feet will kill jiH of 

 the adults. The use of hydrocyanic 

 acid gas is not recommended unless in 

 the hands of a competent fumigator, ow- 

 ing to its deadly poisonous effects. Too 

 much emphasis can not be laid on the 

 fact that fumigation must be set off 

 after midnight to be effective. It is 

 l)referable to start the generation be 

 tween the hours of 12:30 a. m. and 'J. 

 .•I. m. Any fumigation done before mid- 

 night would be useless, for it has been 

 ]iointed out that the adult does not 

 emerge until after midnight. On the 

 other hand, if it is started later than 

 2 ;i. m., many adults will have emerged 

 ,uid laid their eggs. 



' ' In case fumigation is not advisable, 

 esj^'cially where chrysanthemum plants 

 are isolated or when other varieties of 

 plants are present in the houses, spray- 

 ing is recommended. This must be done 

 consistently for a period of four to six 

 weeks, a forty per cent solution of nico- 

 tine sulphate extract diluted (1-800) 

 being used, and soap added at the rate 

 of one-half to one ounce per gallon of 

 solution. The application should be 

 made late in the afternoon in order 

 that the best results may be obtained. 

 In this manner practically all adults 

 can be killed at the time of emergence 

 and !iny eggs present will be destroyed. 



Taking Cuttings. 



"As a i)reventive measure, it is rec- 

 ommended that cuttings be dipped in 

 the following solution at the time they 

 are taken: 



Nicnlino snlpliiilo. fiirty piT cent part 1 



Water parts S1H>

"Another satisfactory method of se- 

 curing chrysanthemum cuttings free^ 

 from midge when the previous season's 

 stock has been infested is to plant tlie 

 stocks in benches or coldframes directly 

 after the season's cro]) lias been re- 

 moved. This should then Ix' followed 

 by thorough treatment with a mixture 

 consisting of etpial ]),'irts of dry, or air- 



slaked, lime and tobacco dust. It is 

 advisable to keep all new growth cov- 

 ered with the mixture until further 

 operations in the spring."

 opened, were on view in the scientific 

 tent of the R. H. S." 



DEMONSTRATING PACKING. 



C. Engelmann, Saffron Walderi, Eng- 

 land, who will be remembered as a vis- 

 itor here about two years ago, does a 

 large export trade in young carnation 

 plants, and often consignments on their 

 journeys to foreign parts are seven or 

 eight weeks before reaching their des- 

 tination. At the recent Chelsea show, 

 in London, he showed two boxes packed 

 eight weeks before the show and two 

 boxes packed four weeks before the 

 show, sealed and signed by 'the presi- 

 dent and the secretary of the Royal 

 Horticultural Society, and placed in 

 cold storage in London. The boxes 

 were sent to Saffron Walden May 22, 

 returned to Chelsea May 23 and oi)ened 

 in the ])resence of the society's oificers. 

 "The plants had not turned a leaf; they 

 looked as fresh and indeed were as 

 fresh and as full of health and vigor 

 as they were when packed," reports the 

 Horticultural Trade Journal. "Neither 

 had any one plant moved a fraction of 

 an inch from its original position, amply 

 demonstrating the suitability of the 

 method of packing adopted. "To see the 

 boxes opened, the carnations looking as 

 fresh as if they had been packed eight 

 minutes instead of eight weeks, made 

 the export of carnations seem easy — 

 but it all dejiends on knowing how to 

 do it. Mr. Engelmann has certainly 

 solved the problem, and can, with con- 

 fidence, dispatch plants to any part of 



FOR NATIONAL FLOWER. 



The daisy, Bellis 1)erenni8, would be 

 made the national flower of the United 

 States, if a bill just introduced in the 

 House of Representatives by Congress- 

 man John Kissel, of Brooklyn, N. Y., 

 were pajsed. The bill has been referred 

 to the House committee on library. 



For some years past there has been a 

 consistent effort upon the part of flower 

 lovers and others to have Congress 

 designate a given flower as a national 

 floral emblem. Most of the bills have 

 called for the selection of the mountain 

 laurel. To date no action has been taken 

 on the proposed legislation and it is 

 doubtful if Congress will act in the 

 matter. 



AZALEA CALENDULACEA. 



I have mailed you a sprig of an azalea 

 l)lant, together with the bloom for iden- 

 tification. The plant from which this 

 was taken is four and one-half feet in 

 height and nine feet across. It has been 

 standing in its present location for 

 twenty-five years without protection of 

 any kind. B. G. — la. 



The plant in question seems to be a 

 form of Azalea calendulacea. This is 

 one of the most showy species. It has 

 orange-yellow to orange-red flowers, 

 which are often two inches broad, but 

 are nearly scentless. The tube is usually 

 shorter than the limb, and the stamens 

 thicken at the middle. C. W.

Maxwell, Neb. — J. C. Parker, who 

 formerly operated a greenhouse at Ge- 

 noa, Neb., is reentering the trade with 

 cut flowers and pot plants. Mr. Parker 

 was compelled by ill health to give up 

 his business in Genoa about five years 

 ago. 



Orlando, Fla.— F. W. Fletcher com- 

 ments on the lack of demand for al- 

 ternantheras this season. He says he 

 is dumping nearly 50,000 plants, al- 

 though he never had better stock, and 

 he wonders if the use of the plant is de- 

 creasing. 



Pana, 111. — The Lions' Club is one of 

 the active organizations of this com- 

 munity. It is devoted to "liberty, in- 

 telligence and our nation's safety." 

 Martin C. Amling is a director. The 

 secretary is Jesse P. Robinson, who 

 also is secretary of A. N. Nielsen, Inc., 

 rose growers. 



Goshen, Ind. — Miss Dora Brown, who 

 for years operated under the name of 

 the Colonial Flower Shop, has moved 

 from her former location, at Main and 

 Jefferson streets, to 219 South Third 

 street, where she has a finely appointed 

 place of business, which is operated un- 

 der the name of Dora Brown's Flower 

 Shop. 



Martins Ferry, O. — Francis Davison 

 has recently completed his fifth green- 

 house at North Eighth and Center 

 streets. He has a fine group of bloom- 

 ing plants on display. 



Elmira, N. Y. — Jay H. Parker, pro- 

 prietor of the Rosery Garden Shop, ex- 

 pects to be able to move into his new 

 quarters ])y July 1. The new quarters 

 of the firm are being erected on North 

 Main street. 



Westerville, O. — A distinctive name- 

 plate is that of Sked the Florist. It 

 was designed by Mr. Sked himself. But 

 then, Mr. Sked's ability is far from be- 

 ing restricted to the growing and sell- 

 ing of flowers. He holds the office of 

 city auditor. He is also .i member of 

 the Board of Trade. 



Omaha, Neb.- — Lewis Henderson, 

 after an active life in the greenhouses 

 and store, has been suffering from ill 

 health for the last four years. He has 

 been troubled with paralysis and has 

 had two cerebral hemorrhages during 

 that time, but he says he is not entirely 

 played out and he still gives the busi- 

 ness much of his attention. Mr. Hen- 

 derson is fortunate in having a son who 

 is rapidly assuming the more burden- 

 some parts of the work.
