because everrthiug is formative, but 

 with good care throughout the season, 

 close, small dumps are formed that 

 will bring excellent results the second 

 season. 



On the side of the divided root you have 

 a reserve force in the tubers that sends 

 the shoot upwards regardless of the 

 soil, and as roots are formed the stalk is 

 nicely growing and ready to assimilate 

 all tlie vitality both clump and root can 

 give. Consequently, as far as the single 

 plant is concerned, the divided root is 

 greatly preferred. However, when a 

 large number of plants is desired to dis- 

 seminate a new variety, the system of 

 propagating by cuttings is the one to 

 be employed and vitality brought up by 

 the second year 's growth.

Dahlia specialists in Europe propagate 

 during summer from cuttings in small 

 pots. The small tubers thus produced 

 are kept in the pots or, which is st> 

 better, packed in dry^ sand in boxes 

 away from frost or heat. The small 

 tubers give better satisfaction than 

 either divided clumps or spring cuttings.

SOCIETY- OF AMERICAN FLORISTS 



Executive Board to Meet. 



The annual meeting of the executive 

 board has been called by President 

 Breitmeyer to convene at St. Louis (m 

 Saturday, March 5. Members of the so- 

 ciety, or others having in mind matters 

 which should be brought to the attentio:i 

 of the committee for the benefit of U\c 

 profession, or the interests of the so- 

 ciety, are requested to send same in 

 writing to the secretary at an early dad'. 

 All such communications will be gladiv 

 welcomed by the officers of the societv 

 and will be given all due attention. Th • 

 sessions of the board will be held at tlif 

 Southern Hotel and wiU probably con- 

 tinue for three days.

THE READERS' CORNER. 



The White Fly. 



Ed. Review: — I have been much in- 

 terested in the recent articles on the 

 white fly, which is indeed a tough pro])- 

 osition. He '"holds the fort" and laughs 

 at our etTorts to dislodge him. He 

 thrives on smoke and as for shower 

 baths of whale oil soap, kerosene or 

 nicotine, they are all the same to him. 

 Let us do justice to the aphis, mealy bug 

 and red spider; they 'take their medi- 

 •cine" and die like true Americans. Not 

 so the white fly. We may make our de- 

 ■coctions ever so deadly and with steady 

 aim and murderous intent discharge 

 them at his innumerable army. And 

 what happens ? He ducks, dodges and on 

 triumphant wing disports himself at 

 a safe altitude until the exercises are 

 over. Then he at once returns to busi- 

 ness at the old stand. 



I am indebted to the white fly; he 

 has given me something to think of. It 

 was a case of conquer or be conquered, 

 and I was about fesigued to surrender 

 when I found liis one vulnerable point. I 

 grow only plants for spring sales, so a 

 very moderate temperature suits my pur- 

 pose. A temperature below 50 degi'ees 

 discourages the white fly and makes him 

 sulky and not disposed to aerial flights. 



Take due notice, therefore, and govern 

 yourself accordingly. Attack him with 

 your favorite "hell broth" early on a 

 cold moriiing and victory .will be yours. 

 I simply used a fine syringe and water 

 at a temperature of 120 degrees and 

 cleaned out the entire swarm except a 

 few stragglers. When I think of the 

 mvriads that threatened to overwhelm 

 me, and now of my clean plants, I know 

 .■iomething of the joys of victory. 



J, Thorxiley, 



That Perpendicular Drop. 



In your issue of January 28 Mr. 

 Scott's answer to Mr. Wallace, on the 

 heating question, interested me very 

 much, particularly where he says: "I 

 must admit that Mr. Wallace is correct 

 in stating that according to the laws of 

 hydrostatics it makes no difference 

 whether the drop in tlie return pipe is 

 six feet in 100 feet or a perpendicular 

 drop of six feet. The pressure where 

 the return water enters the boiler would 

 be the same. Yet in practice the per- 

 pendicular drop has been proved to be 

 the better method," Mr, Wallace and 

 Mr, Scott have evidently both overlooked 

 the fact that they are dealing with 

 water of varying temperature, and there- 

 fore varying density. 



In Avery's Elements of Natural Phi- 

 losophy you will find: "The pressure on 

 the bottom of a vessel containing a 

 liquid is independent of the quantity of 

 the liquid or the shape of the vessel, but 

 depends upon tne depth and density of 

 the fluid and the area of the bottom," 

 Xow when there is a vertical drop in 

 the return near the boiler and the pipes 

 in the houses are nearly level, the ver- 

 tical height of the water is almost en- 

 tirely made up of the portion of the 

 liquid which is the coolest and therefore 

 of the greatest density and does exert a 

 i;reater pressure at the boiler than if it 

 descended gradually, and the average 

 temperature throughout the vertical 

 lieight were greater. 



Again, the vertical rise in the flow 

 near the boiler, where the water is least 

 dense, exerts the least pressure possi- 

 ble in the system. As this arrangement 

 tends to increase the pressure in the 

 leturn and decrease that of the flow 

 and the circulation is directly depend- 

 ent on the difference, it can readily be 

 .*een that there is a very good reason for 

 this method of piping, where it can be 

 had, having been "proved to be the bet- 

 ter method," 



If Mr. Wallace's contention that the 

 vertical height from one end of the sys- 

 tem to the other was the only thing 

 that gave pressure, and if the tempera- 

 ture did not have to be taken into ac- 

 count at the particular place where th" 

 water took its rise, the pressure in both 

 flow and return, having the same vertical 

 height, would be the same ; the system 

 would balance and there would be very 

 little chance of circulation, 



Peter F. D.\lt, 



Owosso, Mich. — The Sunnyside Green- 

 houses are to be doubled in extent this 

 s[)ring, plans now being under way for 

 the erection of about 12,000 feet of glass. 



I7eb.\xa, O. — S. W. Car^y began busi- 

 ness a year and a half ago and has a 

 nic3 trade. He began with two 70-foot 

 houses, put up two more last fall and 

 expects to put up one or two this spring. 

 It is a purely local trade. 



A TOUR OF INSPECTION. 



Two well known growers for the St. 

 Louis market, A. Jablonsky, of Wells- 

 ton, and J. F. Ammann, of Edwardsville, 

 the latter accompanied by his foreman, 

 Henry Blixen, recently made a trip to 

 Chicago and other cut flower growing 

 points. Mr. Ammann told the St. Louis 

 Florists' Club what they saw at its 

 meeting February 11. Here are some 

 of the things he said: 



On arrival at Chicago our first call 

 was on A. Dietsch, the short-roof ma- 

 terial man. There we were taken 

 through the mill and shown how the ma- 

 terial for these successful 'houses is 

 manufactured. Thence we journeyed to 

 Peter Beinberg's wonderful establish- 

 ment. We were a little late but still in 

 time to see the Sunrise in all its glory. 

 After getting lost in these immense 

 greenhouses a few times, we finally met 

 the genial foreman, Mr. Collins. He took 

 us around and introduced us to his 

 honor. Uncle John, and Madam Chatenay. 

 Both were in fine form and regardless 

 of the inclemency of the weather (I hate 

 to speak of it, for it makes me shudder) 

 were in full dress ready for any recep- 

 tion. Uncle John, the bolder of the two, 

 although the younger, impressed us very 

 much and we predict a great future for 

 this rose and will add that if it fills a 

 place in floriculture as has its name- 

 sake, we say, well done. 



Next we went to the Budlong green- 

 houses and found an immense lot of 

 stock, both roses and carnations looking 

 well. Then we went to what they call 

 in Chicago a small place, that of Weber 

 Brothers. This, gentlemen, was a sight. 

 It was almost dusk on arrival there, but 

 those Brides and Maids caused our eyes 

 to open so large we could have seen even 

 were it pitch dark. Four-year-old plants, 

 and to see these two grand old stand-bys 

 done that way one forgets ever wanting 

 anything else. Simply wonderful! Here 

 we also saw the finest house of Liliura 

 longiflorum either of us had ever seen. 

 These men certainly know their business. 



The next morning we were out blight 

 and early, ready for another day's jour- 

 ney. We made a short call at a few 

 wholesale houses and took the train for 

 La Fayette, Ind.. where we called at 

 F. Dorner & Sons ' store. There we met 

 the genial son-in-law and his estimable 

 wife, who has charge of the store. They 

 at once ordered a eariiage and had us 

 taken to the greenhouses. I suppose they 

 could tell by our looks where we wanted 

 to go. There we met the old carnation 

 veteran, F. Dorner, Sr., and his sons, 

 and the old gentleman himself took U3 

 in charge. We were first shown the 

 many thousands of cuttings in the sand, 

 all as clean as could be. Next we were 

 introduced to Lady Bountiful and The 

 Belle. Now there are a pair of beauties, 

 the Lady Bountiful with her dress of lux- 

 urious foliage, stiff stem and beauti- 

 fully fringed flowers and the B«lle, so 

 graceful and a flower as white as white 

 can be. They certainly impressed us as 

 being a pair well worthy of their names 

 and all that has been said of them. Next 

 we were taken to a house of seedlings, 

 and such a sight we never could even 

 imagine. It was here Mr. Dorner realized 

 he had too much of a job to watch all 

 of us, so he delegated his son, a fine 

 young man, to keep an eagle eye on Mr. 

 Jablonsky. He being from Missouri 

 was, of course, considered the most dcs- 

 |ierate and had the old gentleman known
