(See p. 58.) 



In every new discovery or movement words always are 

 coined which are required by the exigency. So that new words 

 or combinations of words are yearly added to our language. 



In this campaign against the mosquito the word petrolize 

 came from over the sea and the word petrolier was found con- 

 venient and £0 was home made — the one referring to the spray- 

 ing of petroleum on water surfaces and the other to the man 

 who does the spraying.
