The deeection may als'o be made by soaking tho stems in 

 water. If one pound of the stems is soaked in one and one 

 half gallons of water for three days or more a deep brown liquid 

 results. For use the decoction may or may not be diluted with 

 water. 



TOBACCO DUST. — Another use to wbieh rcfuse tobáceo 

 may be put is in the form of a ftnely ground powder, mainly 

 applicable against liee mealy bugs and the root infestirig mag- 

 gotts. With the ñrst two pests the application is made by throwng 

 handfulls of the dust in the palee whe're most needed. With 

 the last the tobáceo is placed around the base of the plant and 

 may or may not be covered with earth. 



The dust mixed with cottonseed meal is highly recommend- 

 ed for use upon newly set pineapples. The mixture is placed 

 directly in the buds where it not only serves in protecting the 

 plant from inseets, sand and soil injury, but is equally useful as 

 a fertilizer. 



FÜMIGATION 



Fumigation is absolutely essential in the preservation of 

 many of the stored produets of Cuba. On account of weevil 

 attacks the corn crop is marketed as soon as the harvest is com- 

 plete, bringing but a low price. Were it possible to hold the 

 crop a few months, the selling price could be doubled or tripled. 

 Beans, peas, corn meal, dried meats, tobáceo, all are illustrations 

 of materials very subject to injury and which require the clos- 

 est attention after they are stored. 



CARBÓN BISULPHIDE.— For the destruction of bibija- 

 guas, white ants, small ants and crickts and for the clearing of 

 seeds, grains etc., from weevils this material is considered to be 

 superior to al] others. It is purchased in the from of a liquid, 

 which retails in bulk at the rate of about twenty seven cents a 

 pound, though it may be purchasid in the Unites States for 8 to 

 10 cents per pound.
