 economic instruction, to the various addresses made

DISTRIBUTION OF MATERIAL. 



In pursuance of the plan mentioned in my last biennial 

 report, 14,000 insects were distributed during the winter 

 of 1890-91 to thirty-nine public schools. These sets 

 were named, labeled, and systematically arranged, and 

 were accompanied by printed pamphlets giving the in- 

 formation necessary to make them available for use in 

 the work of the schools. Notwithstanding this heavy 

 draft on our duplicate material, our entomological col- 

 lections are already larger than before the distribution 

 was made. 



The fact that the insects belonging to the State T.,abo- 

 ratory of Natural History ai-e now kept in the University 

 building, and are held at the service of students, under 

 suitable conditions, makes unnecessary any further col- 

 lections, at present, under the law requiring a cabinet 

 of insects to be prepared by the State Entomologist and 

 deposited at the University. 



No collections have been sent during the jiast two 

 years to the State educational institutions or to the 

 State museum, but according to a resolution passed by 

 the State Board of World's Fair Commistsioners last 

 spring, it is held that the collections now being made by 

 the Laboratory for Ex]iosition purposes, will be availa- 

 ble at the close of the l]xposition foi' distribution by 

 the Laboratory to these institutit)ns.
