biology in the public schools. This may be attributed both to the 
lack of space in the public halls and to the failure of the teachers 
themselves to make the Museum an adjunct of the classroom. 
Special classes of exhibits frequently changed and arranged to meet 
the need of both teachers and students throughout the school year 
would do much to advance nature study and biology in city schools 
beyond the stage of bean growing and textbook study. It would be 
to the material advantage of the public schools if the city budget 
could provide a teacher, trained in nature work, to cooperate with 
the Museum in the presentation of materials relating to natural his- 
tory, for under such an arrangement exhibits brought together for 
the purpose could be made to supplement the work of the classroom 
and laboratory.
