 ■icciirate inforiniition, based on careful 

 tests. ex<'ej)t that provided by J. Ver- 

 '•ier, professor of bortieiilture in tlie 

 Oote-d'dr. on "The Utilization of Ar- 

 tifii-ial ('old in I'Moriciilture." which is 

 ]>nblished in 1. 'Industrie Frigorifique, 

 llorists all •well know tiiat the value of 

 lioth carnations and roses is greatly en- 

 liaiiced by subjecting them as soon as 

 ••nt to a chill whicli is just suflicicnt 

 to check the normal vegetative fuiic 

 lions, without destroying them. The 

 'i-iieck should be severe enough to cause 

 the flowers to rest for a jieriod, but the 

 vest should not be a jtermanent one, 

 from which they cannot be roused. Kx- 

 |ierieni-e has dononstrateil that the i-on- 

 ditiim obtaining in the ice box or re 

 I'rigerator where the atmosphere is 

 higidy charged with moisture is better 

 ■suited to the purpose of the florist than 

 'lie same tempera! urt> maintained arti 

 ticially -when the air is dry. Usually 

 t.hc chilling is not long continued, but 

 it is generally believed that a few 

 hour.s' exposure to a low temperature 

 greatly lengthens the perio(l of beauty 

 and usefulness of roses and carnations. 

 While those practices are of great eco- 

 nomic value, even at the present time, 

 there is no reason to doubt that through 

 <'areful investigation their value might 

 be greatly enhanced. 



The wholesale cut flower trade of the 

 great cities of the United States is now 

 ureatly facilitated by the use of modern 

 cold storage appliances. While low 

 temperatures are not desirable, a <'on 

 "^tant temperature of 4it d(>groes for 



carnations and roses is abscdutely es- 

 sential. l''luctuations in temperature 

 and humidity produce great injury, 

 while a constant temperature at a mod- 

 erate degree is the only means of hold- 

 ing delicate flowers over a long period. 

 Su<-li delicate lilossoms as orchids can- 

 not be held in storage at all. They 

 are very sensitive to low temperature 

 and cannot be successfully stored. 



What Is Needed. 



What we at present need :ire care 

 fully condu<'ted cold storage tests with 

 each of the important commercial cut 

 Mowers, coui>le<l with ))ainstaking phy- 

 siological rcsearcdies to determine the 

 exa<'t temj)erature and its duration, in 

 order that the stability of the flowers 

 may be ])reserved to the greatest extent 

 and that tli;>ir duration in an ordinary 

 living room after their withdrawal from 

 cold storage shall be greatest. Without 

 these jiainstaking researches we can 

 iie\er arrive at satisfactory commercial 

 |»ractii'es. Tlie empirical rules which 

 are followed today serve a very useful 

 and valualile jmrpose. 



The value of the cut flower trade in 

 .•iny l-]uropean country or in America is 

 sutlicient to justify most painstaking 

 and car(>-ful research along this line. 

 It is to be r(>gretted that more positive 

 information cannot be given upon these 

 important phases of the cold storage 

 business at this time, but my studies 

 ha\(' thoroughly convinced me of the 

 necessity for careful and extended re- 

 search into thes(^ most imjiortant com

LANTANAS AND HELIOTROPES. 



Kindly tell me when is the Ix^st time 

 to jtropagate laiitanas anil ludiotropes .' 

 If 1 have 11(1 bad luck with mv cut- 

 tings, 1 will lia\e quite an assortment 

 to dispose of. < '. .\. M. 



Cuttings of these shoidd go in at 

 once, as frost is liable to cut them off 

 at any time. Further cuttings can be 

 taken from these during the winter, td 

 pro<luce plants for spring sales. What 

 you put in now will be in the nature 

 (if stock plants. The heliotropes rcipiirc 

 more heat to root them than the Ian 

 taiia<. but both are of easy propagation. 



PROPAGATING BOUVARDIAS. 



1 iia\<' a nice lot of bou vardia^, froni 

 which I would like to grow some young 

 stock. ('an \()u instruct me liowf 



(). L. It. 



.MI the bouvardias are easily propa 

 iiati'd by root cuttings. .Sliake the soil 

 away clean from a W'w jilants and cur 

 the tiiicker ]iortions of the roots into 

 half imdi lengths. Cover them with 

 sand in .a warm propagating bench and 

 kee|i moist, jiotting off singly when they 

 h.-ive started to grow .and make young 

 roots. This piojiagat ion is best done 

 ill niid\viiit(>r. when firing is constant 

 • iiid a steady, brisk bottom heat at 

 comiiKind. r>. llumboldtii is easily 

 |irop;ig;tted from the young, soft growths, 

 whi(di root easily and can be grown into 

 (|iiile large jilants in :i season. .Ml the
