would be the securing of expert advice in reference to the plants 
adapted to interest and instruct the public; the advantage to the uni- 
versity would be the securing of abundant illustrative material without 
the cost of its maintenance. Certainly the parks need to command a 
certain amount of botanical knowledge, and the universities are equally 
in need of a larger contact with plants in their various relations. 
ASIDE FROM the ordinary uses by the university of what is styled 
illustrative material, any large control of planting would secure the 
possibility of experimental work in various biological lines without 
interfering with the legitimate uses of a park. Problems connected with 
heredity would be perfectly feasible, such as otherwise would demand 
the large outlay connected with the equipment of a special experiment 
station. In case of too great distance between the park and university 
a small ‘field laboratory”? would make possible such work as would 
suffer by transportation. It is often said that most of our universities 
have about them wild areas that are a sufficient botanic garden. This is 
true in case botanical instruction and research is to go no farther than 
it has in this country, but it certainly is not true if it is to advance in bg 
directions indicated by the signs of the times. Botanical laboratories, 
to properly maintain themselves as centers of current instruction and 
research, are compelled to provide for plants in masses, grouped with a 
purpose, and subject to control.
