The manures are applied in at-cordance witli the manu- 

 rial .scheme publislied in the AgriruHural N'ewx, Vol. Ill, 

 p. 237, and full i-eports of previous txperinients have been 

 published in the We-it Indian Jiulliiin (Vol. VI, p. 217, 

 Vol. VIII, p. 283, Vol X, p. 269, Vol. XI, p. 00, and \o\.

all the plots is 1,236 lb., or practically the same, and only in 

 one instance, plot 6, has there been an increase of 10 per 

 cent, on the unmanured plots. 



These results, extending over a period of eleven years, 

 are of great importance, and deserving of attention. They 

 tend to prove that under the conditions existing at the 

 Experiment Station, with a loose and open soil, the applica- 

 tion of artificial manures has not so far been attended with 

 remunerative results. 



These experiments are being continued in the coming 

 season on similar lines, on the same plots. 



• NEW SERIES. 



In addition to these plot manurial experiments of long 

 standing, four manurial experiments 1-acre in area were laid 

 out on land that had been under cotton for the past ten years 

 continuously. 



These consist of the following: — 



No. 1 No manure. 



No. 2 Pen manure (20 tons per acre). 



No. 3 Complete artificial manure, nitrogen as sulphate 



of ammonia 308)., potash as sulphate 30Ib., and 



phosphoric acid as basic slag 30 B). 

 No. 4. Clotton soeii meal 600 tt). per acre. 



These experiments suffered from the unfavourable 

 weather conditions of the season, and the action of the 

 manure was not apparent in the returns of seed-cotton reaped. 



The cotton was picked from October to end of December 

 with the results as appear in the following table. It was at 

 first intended to keep this cotton for a second bearing, but 

 the land was required for another purpose: —

 Pen manure — 108 ,, ,. ,, 540 ,, , ,, 

 Artificial manure 104 „ „ „ 520 ,, ,, ,, 

 Cotton seed meal 103 ,, ,, ,, 515 ,, „ ,, 



It will be observed that the mean of the two no-manure 

 plots is 1,213 tt). seed-cotton per acre, while the average of 



Gedar. — Theimjsortof cedar into the United Kingdom 

 according to the Annwd Tfnda Reveiiv, January 1916, totalled 

 433,000 feet as against 534,000 feet and 703,000 feet 

 in 1914 and 1913, respectively. The falling off is accounted 

 for by the lesser quantities received from Honduras, 

 Mexico, Trinidad, and Demerara, but this was oft'-set to 

 a certain extent by an import of 108,000 feet from Argentina, 

 whence none had come to hand in the previous twelve months. 

 The market has been extremely active almost throughout the 

 year, and the small supplies ottered from time to time were 

 readily absorbed at continually advancing rates. The 

 German cigar-box supplies being eliminated, Dutch manu- 

 facturers have done a steady trade with this country, and 

 owing to the difficulty of securing their raw supplies from the 

 producing countries have been active buyers in the English 

 markets. The stock to be carried forward to 1916 consists 

 of 58,000 feet of Honduras, and as supplies are likely to be 

 very short for some time ahead, the high prices now establi.shed 

 are likely to rule for a considerable period, if indeed they do 

 not advance still further.
