and begins to bear in about 6 months. Plants may reach a height 

 of 8 ft. before flowering (Queensland Agric. Journ. ii. 1898, p. 473). 



The Pigeon Pea has been grown in Kontagora, where it reaches a 

 height of 8 or 9 ft. ; the flowers appear in October (seeds sown early 

 in the year), and an abundant crop of peas is borne in December and 

 the following months (Dalziel, Bull. Imp. Inst. 1907, p. 259). 



According to Dudgeon this pea has been introduced to N. Nigeria 

 south of Zaria, and to a small extent into Zaria. He recommends it 

 for growing on land to be fallowed in which situation it yields crops 

 for 2 or 3 years without cultivation, preventing the growth of weeds, 

 and enriching the soil (N. Nigeria Gaz. July 31st, 1909, p. 158). 

 Sown closely and kept well clipped, makes admirable hedges 

 in Zaria (Parsons, N. Nigeria Gaz. April 30th 1910, p. 97). 



Experiments at Onitsha have met with good results (Thompson, 

 Col. Rep. Misc. No. 51, 1908, p. 43). 



A sample of beans from N. Nigeria, examined at the Imperial 

 Institute, shewed the following characters : moisture 11*72 per cent. ; 

 crude proteins 18*40 ; fat 1*42 ; starch &c. 57*12 ; fibre 8*06 ; and 

 ash 3*28 per cent. Commercially the beans were considered 

 satisfactory and suitable for use as a feeding stuff, worth in this 

 country about £6 5s per ton (N. Nigeria Gaz. Jan. 31st 1910, p. 3). 



Almost universally cultivated on red grit or laterite &c. from sea 

 level to an altitude of about 2000 feet in Sierra Leone (Scott Elliot, 

 Col. Rep. Misc. No. 3, 1893, p. 42).
