The treatment of - fever." or whatever tho disease maybe, has been 

 already given in the report of Mr. Fawcett (32). For such purposes a 

 solution of sulphate of copper is hardly safe, as it will concentrate by 

 evaporation in the bases of the leaf-she ove injurious ; 



this is true to some extent of any po*-\ imented with, 



and observations on their ett'eei should be carried out tor a long time 

 and not merely for a wee! -m. Sulphate of copper 



can be much more safely employed in the form of bouillie bordelaise 

 made as follows : — 



1 lb. copper sulphate (bluestone). 



1 lb. freshly burned quicklime. 



to the proper quantity with water. It should be used fresh, and must 

 he kept stirred, as tile copper hydrate formed soon settles. It can be 

 b a syringe or spraying pump, and is not to be regarded as 

 an insecticide. 



The above list of remedies is intended to include all that have been 

 tried and are likely to be of success under different conditions. The 

 protection of the trees against egg-laying by noi trimming them, and 

 the capture of the weevils are, together with the careful destruction of 

 killed trees, the most promising. 



Concerted action has been generally recommended to planters in 

 respect to the destruction of trees, and in order to secure this ordinances 

 have been proposed but not passed into law, both in British Honduras 

 and the Straits Settlements. The reasons for and against such ordi- 

 nances are in large measure independent of the soundness of the economic 

 principles on which they are based. It may be desirable to destroy all 

 infested trees, and yet it may be impolitic to enforce the execution of 



Whether the impulse towards efficient treatment of the evil afforded 

 by the interests of the individual is fitly supplanted by the coercion 

 of the State is a question in ethics beyond the scope of the present 

 paper; but it may be asked whether the destruction of injured trees 18

 who are clearly made to understand that it is t,» their interest and profit 



For unless the duty of inspection : nied, the des-
