House has been changed into an Aeroid House. The old Economic 
House has been changed into the Bay House. At present Mr. Kochhas 
plans for a rearrangement of the Economic and Bay Houses, as soon as 
sufficient funds become available for the construction of the necessary 
retaining walls. In these two houses all specimens are planted in tubs 
or pots, and it has proved impossible to secure the desired artistic 
effects, effects such as could be secured if the specimens could be planted 
in solid beds of soil. 
Permanent plantations—such as those in the Palm, Fern, and 
Aeroid Houses—have been arranged from both an artistic and an 
educational standpoint—that is, to present a lovely picture to the 
eye, while at the same time making available to the student a wealth 
of botanic material, grouped so as to make comparison between dif- 
ferent species and genera especially easy. Mr. Koch has plans drawn 
for a rearrangement of the Economic House wherein trees of economic 
value will be grouped to afford a landscape effect, with shrubs and herbs 
of economic value growing as an apparently natural undergrowth. He 
has hopes of some day arranging an exhibit of Biblical plants in what is 
now the Bay House. He feels that there would be widespread interest 
in such a collection, and the Conservatory has plenty of material to 
serve as a foundation for such a collection—myrtle and olives and figs 
and oleanders and pomegranates and camphire and cedars of Lebanon 
and shittah trees, and the tree that furnished the husks on which the 
prodigal son dined, and many others.
