Close on half a hundred different kinds of Insects caught 

 attempting to run the blockade of the Californian quarantine; 

 and this the fruit of a month's inspection of one tiny stream 

 in the world's great ocean of commerce 1 ! 



1 Since these notes were written the United States, having suffered much, 

 have recognized that the unforeseen introduction of pests has become so 

 serious that a " Notice of Quarantine, No. 37 " has been issued, totally 

 prohibiting "on and after June i, 1919, the importation of such nursery 

 stock and other plants and seeds as harbour certain injurious insects and 

 fungous diseases new to or not heretofore widely distributed within and 

 throughout the United States." 



Britain has not yet instituted a systematic examination of imports for 

 transported pests !
