plants which cannot be grown successfully outdoors; the housing of herbaria, 

 museum specimens, laboratory equipment, library material, office equip- 

 ment and such structures as residences, shop, power plant and storehouse, 

 the whole design to be so arranged and constructed as to present a "tasteful 

 and decorative landscape effect." 



Quoting again from Dr. Britton: 



"In placing the structures intended for the visiting public, considera- 

 tions of convenient access, satisfactory water supply and the distribution 

 of crowds must be borne in mind in connection with the landscape design. 

 The planting should follow, as nearly as possible, a natural treatment, 

 except immediately around the larger buildings, and at the entrances, 

 where a considerable formality is desirable for architectural reasons. It is 

 especially desirable that as much natural treatment as possible should be 

 given to the areas devoted to systematic planting herbaceous grounds, 

 fruticetum, arboretum. The rectilinear arrangement of plant beds found 

 in most of the older gardens has become abhorrent to landscape lovers, 

 and the sequence of families desired can usually be quite as well obtained 

 by means of curved-margined groups. 



Much of the value and the success of a botanical garden arises from its 

 influence in gratifying and developing the innate sense of beauty possessed 

 to a greater or less degree by everyone, and in fostering among the people 

 a taste for decorative plants and a desire to cultivate them. While the 

 beauty of the decorative plants themselves satisfies this hunger for beauty 

 to a large degree, the value and influence of the garden is all the greater if 

 the ensemble effect of the whole and of parts of the garden is the result of 

 the best work of the skilled landscape artist. A fundamental element in 

 the design of a botanical garden is space (or spaces) set aside both outdoors 

 and indoors for the growing and exhibit of plants of economic value. The 

 display of economic plants may be effected by growing such of them as will 

 exist without protection in the locality in a plot more or less individualized, 

 while those too tender for cultivation in the open are grown in the 

 greenhouse, either in a separate house or section, or scattered through the 

 several houses or sections in the temperature best adapted to their growth. 



The display of plant products, best accompanied by mounted speci- 

 mens of the species yielding them, by photographs and plates, is accom- 

 plished by the economic museum where these are arranged in glass or glass- 

 fronted cases suitably classified and labeled. It is believed that the most 

 useful results are obtained by arranging this museum by the products them- 

 selves and thus not in biologic sequence, but by bringing together all drugs, 

 all fibres, all woods, all resins; where the same product is used in more than 

 one industry the exhibit may be duplicated, more or less modified, without 

 disadvantage. 



Whether plants are grown for a demonstration or illustration or a 

 study of their economic value, or whether they are grown for an illustra- 

 tion of their decorative value, the success in either case depends very largely
