LABORATORY EQUIPMENT 13 



(8) An insect cabinet, charts, models and a number of 

 forms foreign to the neighborhood, mounted or preserved 

 in alcohol. These forms may be obtained by buying them 

 from supply houses, but the enterprising teacher will be able 

 to get many desirable specimens by exchange with teachers 

 and students in distant localities. The cost of equipping 

 a laboratory for zoology need not be great. If the financial 

 condition of the school district make it necessary to econo- 

 mize, ordinary tables or desks may be used, hand lenses 

 will take the place of dissecting microscopes, and glass jars 

 may be used as aquaria. 



However, no economy should lead to the attempt to teach 

 zoology without compound microscopes and dissecting in- 

 struments. Text-book zoology is of no value.
