that have become exhausted by other crops may be suitable for 

 pines by growing a crop of cow peas and ploughing them in 

 when in flower. 



"A Jamaica planter, Mr. Smith (Jamaica Bulletin, VII., 

 1900), writes on experience with fertilizer thus: — 'The best 

 results, so far, I have obtained have been from 550 lbs. of 

 cotton seed meal per acre, combined with 100 lbs. of high grade 

 sulphate of potash at time of flowering. I do not seem to get 

 any results at all from phosphoric acid. Stable manure (from 

 horses) should never be used, no matter how thoroughly 

 rotted. The manure from cattle may be used with splendid 

 results.' 



" Mr. Cousins, in the Jamaica Gleaner, November 2, 1903, 

 gives an excellent report on the use of fertilizers in Jamaica, 

 of which the following extracts a.re of interest : — 



" No results whatever from fertilizers were observed at any 

 centre except Clover, near Mandeville, where the results were 

 quite striking. 



11 The Rowington results were not encouraging. It appears 

 likely that after the heavy rains a good deal of surface rooting 

 took place, and that the plants suffered from scorching when 

 the drought followed and the full sun beat down upon them 

 later. 



" On the red soil from the limestone in St. Ann (Huntly) 

 fertilizers produced no effect. This soil is apparently quite 

 rich enough without assistance. 



" At Barbican, on the alluvial soil of the Upper Liguanea 

 plain, fertilizers were quite iuoperative. This soil is apparently 

 richer than the maximum requirements of the pine in plant 

 food. 



" At Billy Dun, on a similar soil with less humus and ex- 

 posed on a hilly slope to intense heat, fertilizers were alike of 

 no avail ; the plants suffered greatly from scorching. 



" The experience of the Hon. Phillip Cork, when he grew 

 pines at Barbican, is in agreement with these results. Even 

 enormous doses of fertilisers proved ineffectual when applied 

 to the pines. 



"The phosphate fertilizers had absolutely no preventitive 

 effect on the formation of ' coxcombs ' on the United Fruit 

 Company's plantation,
