PLANTS OK THE WORLD'S FAIR GROUNDS. 141 



extensive nursery displays of woody ornamental plants, if they 

 should be placed, as a whole, in any of the following classes of 

 horticulture, or subdivided between them : Group 22. Flori- 

 culture. Classes, 147, roses; 150, rhododendrons, azaleas, etc.; 

 156, climbing plants; 161, ornamental leaf plants; 166, rare 

 exotic plants; 168, plants grown for commercial purposes; 

 171, miscellaneous. Group 25. Arboriculture. Class 185. 

 Ornamental trees and shrubs j methods of growing, trans- 

 planting, etc. 



" There were errors of omission in the classification, as 

 well as repetitions. Weeds were not mentioned. Insects and 

 means of combating them were mentioned in one or two 

 groups, but not in floriculture, cereals and forage plants. 

 There was no place definitely provided, in any of the depart- 

 ments, for plans of landscape architecture, notwithstanding 

 that so much of the artistic success of the grounds and build- 

 ing was due to this profession. There were garden and park 

 designs in the Horticultural, Agricultural, Ethnological and 

 Liberal Arts Buildings. 



" The interests which contribute to either horticultural or 

 agricultural displays are the forester, farmer, market gardener, 

 fruit grower, live stock raiser, nurseryman, florist, seed grower, 

 and the manufacturer of appliances, tools, materials and ferti- 

 lizers required to produce and handle their products, and the 

 various scientific interests represented by the experiment sta- 

 tions and the government departments. These interests would 

 include the products of the soil, the diseases affecting them, 

 the appliances used in producing, improving, marketing and 

 preserving them. How far they should be extended to include 

 the materials manufactured from these natural products may 

 be an open question. At the World's Fair, wine was in Horti- 

 culture, whisky in Agriculture, cider in both, animal perfumes 

 in Agriculture, essential oils from peppermint, etc., in Manu- 

 factures. Would not a consistent classification exclude man- 

 ufactured articles entirely from horticulture and agriculture ? 



" At the World's Fair, forestry was a department of agri- 

 culture, and the products of the fruit grower, the florist, and 

 part of those of the market gardener, were under horticulture. 

 In the subdivisions of a classification, all well defined interests 

 should be distinctly recognized as divisions or classes, and it 

 should be possible for them to so classify or label the various 

 exhibits, so that all the other interests could easily secure 

 information that they required for their special pursuits. Such 

 interests as forestry, entomology, botany, mycology and chem- 

 istry are certainly distinct enough to be thus recognized. The 

 seed trade, for example, is as distinct as the nursery or florist
