TABLE SHOWING AMOUNT OF WATER USED AND 

 SUGAR PRODUCED. 



These figures are very instructive and show that the yield of sugar 

 was almost proportional to the amount of water applied to the cane, 

 and illustrates what wonderful results are possible with good soil, 

 plenty of fertilizer, and plenty of water. 



You have in Fajardo a very great advantage in that your soils are 

 heavy and hold the water for a long time. Frequent irrigations then, 

 even in times of drouth would not be necessary. In fact I believe 

 that a very few irrigations per year would be sufficient in most years 

 to maintain the proper amount of moisture in the soil for good crops 

 of cane. Your method of planting cane would have to be changed, 

 but this would also be a benefit rather than a detriment. Where irri- 

 gation is practiced the cane is placed in deep furrows, '"chorro", and 

 water is run directly in these furrows. For ratoons you would either 

 run the water in the cane row, or hill up the ratoons, making a 

 depression between the rows into which the water is run. Whenever 

 irrigation is adopted you use more fertilizers, for fertilizers pay best 

 where there is an ample supply of water. 



The following table gives the rainfall at Fajardo for the past 13 

 years the same having been furnished by the U. S. Weater Bureau at 

 San Juan:
