actual results obtained on two estai s in Barbados. The

The present time is opportune for noticing the 

 suitability of different varieties oi ir different localities. 



The student should notice carefull) the varieties on the 

 experimental pints, and make notesand, it' possible, estimate-., 



in yield per acre, and compare these notes as faras possible 

 with the official results, which will be published early next 



year. 



Questions for Candidates. 



PRELIMINARY . 



1. Name som< mmon plants in which starch is 



produced in quantity, and state in what part oi the plant the 

 starch is stored 



2. Explain the difference between Pollination and 

 Fertilization. 



INTERM I in \ I I 



1. Describe the preparation oi assava and irrowrool 



starch. 



•_!. Describe carefully the appearand _ I sample 



of either (a) concentrated lime juice, or (b) cane syrup. 

 Explain how the one you -elect is tested. 



FIN \l.. 



1. Discuss the establishment I value of wind-breaks 



from as many points of view as pos 



2. State fully the uses that are made of the bj in 

 0O an estate with which you are i i linted. 



Of two alternatives, a short rrflp and high prices IS 

 better for the planter; but a heavj crop ami low prices is 

 better for the labourer. Both are itisfied with high prices 

 and heavy crops. 



A FLYING-PISH PARASITE.

embedded in the tl.--li ol the fish, and parti ding. 



The fishermen and others who milia 



parasites -peak of them as 'feathers'. 



Specimens recently f'oi warded to thi Bri mm 



(Natural History) have be n reported on, and thi 

 reproduced in the following paragraph: 



FLYING-FISH PARASITK FROM BARBADOS, SENT BY 



DR. II: wi IS W \ its, i .m.i.. 



'The two specimens are parasitic Copepoda (< 

 of the genus Pennella. They probably belong to the - 

 P. exocoeli (Holten), but the head is absent in one a I 

 badly damaged in the other, so that the specific ch 

 lannol be determined. The Museum would be _ 

 receive perfect specimens. Unless the parasite cat 

 .ii fully dissected out on the spot, the whole fish should be 

 preserved, and specimen- should be looked for which carry 

 egg-strings a pair of long, light-coloured filament 

 .i the tree end of the animal, easily to be distinguished from 

 the brush of short, dark coloured filaments which are believed 

 to act as ".in.,. The lifi bistor) of the genus is no doubt 



- lar to that of the genus Lernaea which is describ I i 



must text-books.' 



The following, taken from the Cambridge V 

 History, is presented herewith as likely to be oi interest in 

 tlii- connexion. 



FAM. II. LERNAEIDAE. These parasites burrow 



their heads deep into the skin, or even into the bl< 



or body-cavity of various marine fish. The body of thi 

 female Lernaea is extraordinary deformed, consisting >J 

 a mere shapeless sac with irregular branched processes 

 head, and two egg- sacs attached behind. Pennella ■ 

 bores so deeply into the flesh of its host, 



wratus, that only the egg-sacs and some remarkable 

 branchial processes attached to its abdomen protrude outside 

 the host to the exterior. Peroderma cylindricum 

 similarly into the flesh of the Sardine, and where it is 

 mon, inflicts considerable damage. The males of these 

 curious animals are of more normal structure. Clans states 

 that fertilization takes place when both sexes are free-swim 

 ming, and of a more or less similar structure, and that subse 

 quently the female beomi ■- fixed to her host and J. . 

 into the shapeless mass shown.

 ing the extent of the imports "t Indian com into that ( lolony 



from 1899 up to 1911. Although there is a much 

 quantity of maize imported into Trinidad than is necessary, h 

 should be remembered that there has been a steady red i 

 in the imports during thi period under review. In 1899, 

 the imports were nearly 1,000,000 ft).; this figure di 

 steadily down to 1,000,000 ft. for 1911. ft is pointed out 

 that it should not be necessary to import Indian corn into 

 Trinidad at all, since the crop can be easily grown in
