The first method is to pin leaves bearing the dead bodies 

 of the white fly larvae npon the infested trees. 



The second method is to plant small trees the leaves of 

 which bear the dead Larvae, elose beside the tree to be in- 

 oeulated. 



The third method is to prepare a water solution of the 

 bodies of the larvae dead with the fungus and spray it upon the 

 trees with a spray, pump. 



To the author's knowledge there has been as yet, no exten- 

 sive work along the lines of artifically propagating and distri- 

 buting beneficial fungí in Cuba. The white fly is not known to 

 be pressent now, but many of the seales are attaeked by fungus 

 and Nature's proceses eould undoubtedly be asisted materially 

 with very little labor. Probably the most simple method of 

 spreading the fungs is the second orne previously refered to, but 

 at this time no specific recommendations can be given.

BORDEAUX MIXTURE.— The foUowing directions for 

 preparing Bordeaux mixture are taken from Circular No. 30 of 

 this station "Bordeaux mixture is a well known preparation for 

 checking fungus diseases on plants. It is made by uniting sulpha- 

 te of copper with lime in a special way and cannot be purchased 

 ready made in a satisf actory f orín but must be prepared where it 

 is to be used and applied within a few hours. The principal 

 inconvience with making Bordean mixture in Cuba is the diffi- 

 culty of securing good quick lime. Air-slacked lime will not 

 make good Bordeaux, and the hottest, freshest quick lime avail- 

 abie should be used. By the following methods we have suc- 

 ceeded in making a serviceaoble Bordeaux". 



"Take a quantity not less than a sack or a barrel ot the 

 best, hottest quick lime which can be secured. Slack this care- 

 fully with water, not using more than enough to keep the lime 

 moist, until thoroughly slacked, then add the water to make a
