OIL BEANS, SEEDS AND NUTS 449 
and subject to being shipped in lots of fifty to one hundred tons at a 
time. No regular plantations have been made with this tree, but 
it is probable that with cultivation an earlier and quicker yield of 
nuts could be obtained, also with further grafting and seed selecting 
the thickness of the shell over the kernel could be considerably reduced, 
and also the thickness of the pod, and thus make the product more 
valuable in proportion to its size. A small tree will bear half to one 
bushel of beans, and a large tree will bear two. On the smaller and 
younger trees the pods are narrower and shorter than on the older 
trees, and the beans are much smaller, being only about half the size 
and a third of the bulk of those from fully-grown trees. The pods, 
which also contain a certain amount of oil, are not to be despised as 
a source of fuel, especially as time goes on and the population increases. 
In this place also should be considered the beans of Xylia Hvansii. 
This is also a Leguminous tree. The natives apparently have no use 
for the small, flattened round beans, which are about half to three- 
quarters of an inch in diameter and an eighth of an inch thick, and 
sometimes less. The beans have not been collected or sold, neither 
have they been examined chemically as to their oil or other content. 
Another oil-bean-bearing tree of this family is Berlinia acuminata, 
which has large beans rather more than an inch and a half long, 
an inch broad, and a third of an inch thick. Further examination 
would show whether the oil content is such as to justify their com- 
mercial exploitation. The Benin name is Ekpagoi and Yoruba 
Apado. 
Closely allied to this one is Macrolobium palisoti, the Ogaba of the 
Benis, which also yields a flat, almost square-shaped bean, nearly an 
inch in length and an inch in width. The exact oil content of this 
bean is unknown. 
The beans of Cynometra Afzelii and Cynometra Mannii are much 
larger and stouter, but also contain a certain amount of oil of unknown 
value. The Benin name is Upakeka and Yoruba Eggi or Ekku. 
Then we have the small, almost black, button-like beans of Brachy- 
stegia spiceformis, which, despite their large quantity, have remained 
uncollected and unused. <A proper chemical examination would reveal 
the oil or other content of the beans. The Benin name is Okwan 
and the Yoruba Ako. 
Still considering this same family of plants, the Leguminosee, 
there are the brown beans of Hrythrophlewm Guineense and E. micran- 
thum. These are of a brown colour, about half an inch long, one- 
third of an inch wide, and an eighth of an inch thick, and of a more 
or less round shape. Here, again, further investigation would reveal 
the oil content of these beans. The Yoruba name is Oginni or Inyi 
and Yoruba Erunor Obo. 
It is also not known whether the nuts of the various Afzelias,
