it does not carry a single specimen of the San Jos^ scale. If

" We wish particularly to impress upon the minds of fruit- 

 growers that as soon as this insect is found to occur in an 

 orchard the most strenuous measures must be taken to stamp it 

 out. No halfway measures will suffice. The individual must 

 remember that not only are his own interests vitally at stake, 

 but those of the entire community in which he resides. Trees 

 badly infested should be instantly burned, as previously stated. 

 The individual may think that he cannot bear the loss, but the 

 loss in consequence of the slightest neglect will be much greater. 

 The fact, too, that there is a community of interests among fruit- 

 growers in this matter must not be lost sight of. Fruit-growers 

 must be mutually helpful in an emergency like this."
