THE SAN JOSE SCALE. 91 



and mix with the boiling mixture. (It would be better 

 that all such preparations be made out-of-doors, or in 

 some place detached from a dwelling.) Add more water 

 up to 60 gallons, strain, and apply warm. Use gloves to 

 keep the wash off the hands, and thoroughly clean and 

 wash the spray pump after using this mixture. Do not 

 use a copper vessel in Avliich to boil this mixture. 



Soap Wash. 



Whale-oil soap and hard soap dissolved in hot water 

 and applied warm : — 



Whale-oil soap, 1^ lbs. 

 Ordinary hard soap, ^ lb. 

 Water, 1 gallon. 



In addition to the above must be mentioned the resin 

 compound, a most valuable and effectual wash for scale 

 insects ; also the hydrocyanic gas treatment, as practised 

 by us at the Burnley Gardens, and before alluded to. 



With regard to a funo;us (^Sphcerostilbe coccophila^ 

 Tul.) which has been introduced from Florida into two 

 orchards in scale-infested portions of the United States, 

 Professor Smith, one of our best authorities on the sub- 

 ject, says — " In one of these two orchards it has become 

 very well established. If it passes the winter success- 

 fully it may prove a useful means of reducing the scales 

 to harmless numbers, and in such cases the disease should 

 be distributed wherever the insects themselves occur." 



In Victoria, as elsewhere, we have probably many 

 minute flies, also beetles, which will attack this scale, as 

 they do other kinds, still we who wish to stamp it out as 

 soon as possible, nuist not put too much faith in natural 

 checks but must keep the spray pumps going, and, as 

 showing what can be done, Professor Smith says — "It has 

 been proved beyond all doubt that whale or flsh oil soap 

 will kill the pernicious scale if applied at the rate of two 

 pounds in the one gallon of water at any season, and half 

 that strength will kill all that are hit by it in summer. 

 The larv8B succumb to even weaker solutions."
