effect on the growth of the plants, and can be recommended for 

 oranges planted in similar comparatively dry situations. 



Leguminous plants, such as Cow Pea, Hairy Yetch, and Conga 

 Pea have been largely grown through the plantation. These not only- 

 shade the ground, and, to a certain extend retard, or altogether prevent 

 the growth of weeds, but they also increase the supply of nitrogen in 

 the soil. 



Nitrogen is an important part of the food of plants, and as matters 

 containing it exist only sparingly in most soils, and as they are easily 

 exhausted, it becomes necessary to adopt other means of keeping up 

 the supply of this aliment. Mr. H. J. Webber of the U.S. Depart- 

 ment of Agriculture speaking of nitrogen as a fertiliser for oranges says : 

 " A grower may with considerable certainty determine by the ap- 

 pearance of bis trees the condition of his grove in respect to the supply 

 of nitrogen available in the soil. An abundance of nitrogen is indi- 

 cated by a dark green colour of the foliage, and rank growth . . 

 . . . If the trees have a yellowish foliage, with comparatively small 

 leaves, and show little or no growth, there is probably a lack of nitro- 

 gen ..... If the tree is starving from a lack of nitrogen, 

 the foliage will become very light yellow, and sparse, and the small 

 limbs will die, as will also the large limbs in extreme cases. If the 

 starvation is continued, no fertiliser being added, the tree will finally 

 die back nearly to the ground, and probably die out entirely." 



Fertilisers are expensive, and require to be applied with considera- 

 ble judgment and care, the use of green manuring, therefore, is advo- 

 cated as being a more economical and less risky method of supplying 

 the desired elements.
