Conclusion. — The three remedies given here : — 



1. Collecting the eggs. 



2. Destroying the moths. 



3. Cutting out nffected canes 



if carried out ener getically and intelligently from the first cannot fail 

 to destroy great numbers of moth-borers. Not only will the canes be 

 more vigorous and sugar obtained that is now destroyed by millions of 

 borer cat^rpi lars, but the rind-fungus would I think, be greatly dimi- 

 nished. Up to 1 December in each year, rind fungus only gets into 

 such young canes rs have been bored by moth-borer."* If it is pos- 

 sible bv collecting the eggs, cutting out dead-hearts, and catching the 

 moths at lights, to prevent the catei pillar from boring the canes, rind 

 fungus will no doubt be greatly diminished *'0f all insect enemies 

 of the sugar cane the moth-borer is certainly the most serious i^i Bar- 

 bados. It attacks all varieties of canes, and hence is not only con- 

 stantly exposing them to the attack of Fungi or Hacteria, but would in 

 manj^ cases, carry the very spores into its burrows ; besides which, the 

 injury suffered by any cane by the actual attack at least leads to im- 

 poverished juice, if not to actual death of the plant. A glance at any 

 of the literature of the cane diseases will convince anyone of the im- 

 portance which eveiy cane-growing country has attached to checking 

 the sprtiid of the pest."t 



The concliis'on cannot be avoided that sugar planters can now choose 

 between getting all the sugar their land will yield them, or letting the 

 moth-borer yearly rob them of a large portion of their canes Every 

 cane xhut is bored will on being ground yield less sugar than it should 

 and will also give juice containing substances that tend to sj)oil the 

 cane juice. Goi d sugar cannot be obtained from canes attacked by 

 moth-bonr or rind fungus, as acids and other injurious compounds ara 

 f ( rmed as the result of the attack. It will well repjy e eryone inter- 

 ested in sui-ar planting to see that these remedies a e adopted immedi- 

 atel}- the moth-borer is seen to be at work in the cane fields. 



NOTES ON SOME ANDROPOGONS IN JAMAIOA. 



By Wm. Harris, F.L.S. 

 Acting Director of Public Gardens and Plantations. 



Andropogon is a genus of gr<i88es of various habit. There are about 

 200 species, chiefly tropical, and several of these are of economic value, 

 Tt e following are cultivated at the Hope Experiment Station 



Andropogon squarrosus, Linn. f. {A. muricatus, Ketz.) This is the 

 Khus-IihuSf or Governor Grass. It is found throughout the Plains and 

 Lower Hills of India, Burma, and Ceylon, and is cultivated in the 

 tropics generally. It grows in large, dense tufts, with stout, spongy 

 aromatic roots which are sparingly branched. The leaves are 1 to 4 

 feet long, narrow, acute, erect, with scabrid margins. Panicle 6 to 12 

 inches, conical, erect, borne well above the leaves, purplish in colour.
