SOME EXPERIMENTS IN THE EXPORTATION OF BENE- 

 FICIAL INSECTS.* 



BY F. M. WEBSTER, WOOSTER, OHIO. 



I do not wish by this title to imply that there is not to be another 

 phase to this experiment, but owing to climatic differences between Ohio 

 and South Africa, whereby our winter months are their summer months, 

 the export side of the problem came first. Next autumn, in South Africa, 

 but spring with us, the tide of transportation will set in in the other 

 direction.
