COOK, THE RED SCALE 21 



summer just after all the fruit is gathered, as then we have only the scale on 

 the leaves and twigs to combat ; but as we would hasten if fire was nearing 

 dynamite so we must not delay if we discover red scale in our orchards. For 

 the purple scale and for the mealy bug, double the black scale dosage is 

 required, and for the red and yellow scale it may be economy to hit as hard. The 

 Woglum system of marking the tents and amount of cyanide to be used, must be 

 followed. There is no excuse now for any guess work. The loss sufifered by our 

 growers in the past, by faulty guess work and too slight dosage, has been 

 enormous. Nor is it enough, as we have been doing, to simply fumigate our 

 citrus trees. We must look after every tree, shrub and plant that harbors the 

 scale in question. 



May I, in closing, emphasize four vital points, the observance of which, in 

 the past would have saved hundreds of thousands of dollars to our orchardists ; 

 and the observance of which can and must save, in the future, fortunes to our 

 people. First we must have thorough inspection, that every orchardist shall 

 know just the condition of his orchard. Secondly, we must have a sufficient 

 dosage, that will always kill the scale, though the tree is a little burned at 

 times. Third, we must have fumigation by the block system, and thus save 

 the necessity of fumigating oftener than once in three or four years. Lastly, 

 the Exchanges must do the work, as this alone will insure that the scale will 

 always be "hit hard." Absolute thoroughness is the Golden Rule in fumi- 

 gation.
