The Florists^ Review 



13 



Floral Decorations Filled the Corridors of the Marine Bank & Trtist Co., at its New Quarters* In New Orteans. 



No. 37 will be discussed by a speaker 

 to be announced later. 



Members should not delay in making 

 reservations for hotel accommodations, 

 and should apply to James Fisher, chair- 

 man, hotel reservations committee, 

 10504 St. Clair avenue, Cleveland. 



DECORATIONS AT BAITK OPENING. 



Floral decorations of every kind filled 

 the corridors of the Marine Bank & 

 Trust Co., in its new quarters, on Caron- 

 delet street, New Orloajjfl, at its open- 

 ing, June 30. A large proportion of 

 the wreaths and' sprays came from the 

 Motairie Eidge Nurseries, but all the 

 principal florists of the city were well 

 represented. The bank was organized 

 about one year ago and has risen rapidly 

 in piiblic favor, the deposits now reach- 

 ing upwards of $12,000,000. 



TOEONTO, ONT. 



Convention Plans Complete. 



The final program for the Canadian 

 Horticultural Association convention is 

 out and it shows that there will be some- 

 thing doing all the time. The date has 

 been set for August 12 to 15 inclusive, 

 so that visitors from the United States 

 can take in the convention in Toronto 

 on the way to Detroit. A cordial invi- 

 tation has been extended to florists, 

 growers and supply men of the United 

 States to take in the Toronto conven- 

 tion. Supply houses desiring space for 

 exhibition purposes should advise either 

 A. Simpson, 11 Queen 's park, or J. J. 

 Higgins, superintendent of exhibits, at 

 once, in order that reservations may be 

 made. All desiring hotel reservations 

 should advise H, G. Dillemuth, chair- 

 man of the convention committee. 

 Goods for exhibition purposes only will 

 be admitted duty-free. 



Social features include a- banquet, 

 visit to the greenhouses of Sir John 

 Eaton and Sir Henry Pellatt, and a visit 

 to Victoria park, at Niagara Falls. All 

 attending the convention will be the 

 guests of the Toronto Retail Florists' 

 Club Wednesday afternoon, August 13, 

 at Long Branch. Automobiles and elec- 

 tric cars will take the crowds to the 

 park free. There will be a good pro- 

 gram of sports. Valuable prizes will be 

 given. An orchestra will be in attend- 

 ance, supper will be served and the even- 

 ing spent in dancing. The club will pay 



all expenses. Preparations are being 

 made for over 500. J. Plumptree will 

 be director of sports. 



^ Various Notes. 



A trip to a number of greenhouses 

 shows that they intend taking care of 

 the anticipated increased business next 

 winter. Material is now on the ground 

 for the additions at the Dale Estate. 

 Simmons & Son are also increasing their 

 greenhouses at Brampton. J. H. Dun- 

 lop will soon have his new greenhouses 

 at Richmond , Hill. The Bedford Park 

 Floral '(R. has ground near Mr. Dunlop 

 and by next year will probably under- 



take the construction of a complete new 

 range at Richmond Hill. Other growers 

 are taking advantage of the season to 

 make much needed improvements and 

 additions. 



George M. Geraghty, the manager of 

 J. H. Dunlop 's, took a party of twenty- 

 one returned soldiers for a month's 

 holiday to his summer home, Pilgrims' 

 Rest, on Georgian bay. 



S. McFadden, manager of S. Tidy & 

 Son, and family, are at Otter lake. 



H. G. Dillemuth is on a fishing trip 

 at Lake Magnetewan. He remembered 

 'the boys in the Store and friends with 

 some speckled beauties. J. J. H. 



CHEMISTRY HEIiPS GROWERS. 



[This is the third Installment of the article 

 by E. A. White, professor of floriculture at 

 Cornell University, Ithaca, N. Y., on "How 

 Science Aids Florists."] 



As has been stated, next to botany in 

 its various divisions, probably no branch 

 of science has been more beneficial to 

 floriculture than chemistry. Botany and 

 chemistry are so interwoven in plant 

 culture that it is impossible to state the 

 relative importance of each. The ap- 

 plication of chemical principles touches 

 many phases of plant life closely. Both 

 organic and inorganic substances must 

 be studied; air, moisture and the soil 

 elements, which make life possible, are 

 all intimately bound up in chemical 

 substances. 



A study of the atmosphere in its re- 

 lation to plant life, and of the soil in 

 its relation to vigorous plant growth, 

 brings us closely into the chemical 

 world. In earlier horticultural practice, 

 little attention was paid to atmospheric 

 conditions. The air as a source of plant 

 food was unthought-of, for the plant 

 growers of that early period had little 

 to aid them in solving their problem 

 regarding the source of material for im- 

 proving the growth of. their plants. 



Atmosphere and Plant Growth. 



For years there was a realization that 

 the nature of the soil was important for 



healthy growth, but only within com- 

 paratively recent times has there come 

 to be a realization that the atmosphere 

 is equally important. Outdoor atmos- 

 pheric conditions are little subject to 

 control, but in greenhouses the plants' 

 environment in this respect may be more 

 easily governed. With the discovery 

 that a large percentage of a plant's 

 substance was carbon, and that the 

 plant received this carbon from the air, 

 there came to be a better appreciation 

 by plant growers of the fact that plants 

 are as dependent on a liberal supply 

 of fresh air as is man. 



The greenhouse builder, therefore, be- 

 gan to consider the principles of ven- 

 tilation, and although present-day meth- 

 ods of greenhouse ventilation are ex- 

 tremely crude, nevertheless plant 

 growth under glass is much more healthy 

 than in the earlier days, when it was 

 thought that all that was necessary 

 was to give the plants warmth and 

 light. Consequently, the early green- 

 houses were small and sunken in the 

 soil so as to retain all the heat, and 

 every possible effort was made to pre- 

 vent the escape of warm air from the 

 greenhouses and to let little fresh, cool 

 air in. In this way the plants became 

 so susceptible to fungous diseases that 

 it was almost impossible to grow many 

 species.
