 fumigators and so on, are but makeshifts, that 

 they are expensive, and that they cannot be

 has somewhere a good bug to kill the bad 

 bug; it is man's part to find the first and lib-

The attention of other states is being called 

 to this remarkable work, with the probability 

 of its indefinite expansion. There appears to 

 be no reason why it may not be made to 

 include practically all the insect pests. The 

 national government has recently been at 

 work along the same line, seeking to locate
