ninety thousand or twenty-seven million. Now multiply 

 twenty-seven million by another three hundred, and you get 

 the enormous number which would infest the whole state of 

 Connecticut if nothing was done to check their growth. The 

 most amazing and convincing lecture on the gypsy moth that

 Van Slyke has failed to make connection, but he will be here 

 at 2 : 34. In the meantime Mr. L. A. Clinton of the Storrs 

 Experiment Station, will present his paper on the most 

 economical sources of nitrogen for plant food, which was to

 Storrs, and he will present his paper now so as to occupy the 

 time until Dr. Van Slyke arrives.
