 "When plantations are situated on the banks of a river every 

 effort is made to get the fine sediment brought down by the river 

 when in flood well spread over the land. 



Irrigation is by means of the old-fashioned conduit system. 

 The plant, especially as it matures, needs water naturally in con- 

 siderable quantities, and more particularly when chemical 



manure 



Planting takes place in the 



readily absorbed by the small roots. 

 Season for planting and crop, — 

 epring, the precise time varying here between March, April and 

 May, each of these months being considered '^the best,'^ an 

 opinion properly formed locally and based upon the variation of 

 soil, site, etc., etc. The crop should be ready for cutting one 

 year after planting. 



Average yield, — The average yield is said to be about 40 tone 

 for 2\ acres. The crop from the Adra plantation is stated to be 



200 arrobas (2300 kgs.) from a *^marjal,^' or 525 square metres 

 for the ^^ tercio " or first year's cane, and 300 arrobas 

 (3450 kilgs.) for the *^ Alija " or second year. This statement also 

 shows the great increase of the second-year crop over the first. The 

 density of juice is stated to be ^^8 degrees Beaumet," or *^ about 

 '* 14 per cent, of the output of cane, for the district generally '^ ; 

 whereas at Adra ^'the average yield of sugar is said to be
