60 MISSOURI BOTANICAL GARDEN BULLETIN 
The faculty consists of the following: Dr. George T. Moore, 
Director; Mr. G. H. Pring, Horticulturist and Superintendent 
of the Garden, also Co-ordinator of the Vocational Students ; 
Dr. Edgar Anderson, Geneticist; Mr. L. P. Jensen, Arbori- 
eulturist; Mr. P. A. Kohl, Floriculturist; Mr. John Noyes, 
Landscape Designer; and Mr. John Kellogg, Herbarist and in 
charge of Nursery. 
Mr. G. H. Pring, our co-ordinator, has instituted an after- 
noon lecture, a little out of the ordinary in that our lecturers 
are two of the voeates. The subjects covered to date are: 
bedding plants, floral display, carnations, cycads, ferns, palms, 
roses, orchids, mums, pruning, grafting, budding, ete. 
The lecturers read their lecture at first, but now they speak 
extemporaneously and use notes. The lecture uses an hour 
or more, after which we have a discussion. Hach student 
must study the subject thoroughly, else Mr. Pring may ask 
him to explain his question. And each student tries to have 
a question that will cause the lecturers to do some deep 
thinking to answer it. 
To give an idea as to the subject matter, we will take the 
lecture on ferns, as given by Harry Schramm and M. J. 
Benda. Schramm had the propagation and culture, and 
Benda the history and evolution. The propagation was by 
far the harder to give, due to the fact that so few persons 
know the structure and reproductive processes a fern goes 
through. Schramm told us when to gather the spores, when 
to sow; moisture conditions; when to transplant; pests and 
diseases and control. 
Benda gave us the history ; where the fern stands in relation 
to other plants. He gave us the botany of the fern in so 
simple language that our less-educated comrades could under- 
stand. 
Jansen started the discussion by asking Schramm how to 
figure the cubie feet of a greenhouse. Wahl asked if the fern 
was a monocotyledon or a dicotyledon. Zeiner asked if the 
mealy bug could be killed with nicotine. Aubuchon asked if 
ants were harmful to ferns. Holton wondered if either lec- 
turer could tell him why some Boston ferns were plumose. 
Lance asked Benda if the reproduction were sexual or asex- 
ual. Ward asked Benda what conditions were necessary for 
the antheridia to get to the archegonia on the prothallus.
