ship of qualified teachers or other persons whose interest can be enlisted, 

 may, by excursions to parks, seashore, or to streams, ponds, lakes in the 

 open country, become acquainted with specimens of aquatic life in their 

 natural habitat. 



2. Lecture service for the general public. This may take the form of 

 lectures before many different kinds of clubs and organizations, radio talks, 

 etc. Both for school work and for this general service it would be desirable, 

 if funds would permit, to have on the staff of the aquarium one or more 

 qualified persons whose entire time would be taken up with this kind of 

 service, for obviously the regular staff will hardly have the time and energy 

 to conduct such a service to its maximum possibilities. 



3 . Publication of pamphlets and booklets of general informational interest. 

 The guide books usually published by aquariums are of very great value 

 from a general education standpoint. Such publications as to the con- 

 struction of small aquaria; aquaria in homes; how to care for specimens in 

 small aquaria, etc., are of value. 



4. Scientific contributions of aquariums. Some of the aquariums have 

 laboratories where instructors and advanced students from higher insti- 

 tutions of learning are allowed to pursue original investigations. The 

 aquarium is in itself a laboratory of very great value, and it is not surpris- 

 ing, therefore, that from aquariums in charge of scientifically trained staffs 

 many valuable contributions of a scientific nature relating to aquatic life 

 forms are constantly coming. The publications of this nature from the 

 New York Aquarium are voluminous and of a very high order of scientific 

 merit.
