the oil. The oil differs in different parts of the Colony and 
Protectorate. ‘The merchants state that some of the oil which they 
get in the district adjoining the railway line is equal to the best 
quality of Lagos oil and is superior to the Sherbro oil ” (Haddon 
Smith). 
In the Gambia the oil is extracted in a manner similar to that in 
vogue in Lagos. 
“Pericarp oil or ‘ Tulu sayi’ in Mandingo, is made as follows 
and is a dull red :— 
“1st, The fruit is plucked from the cob and put into a large pot of 
water and boiled until the pericarp is loosened from the shell of the 
nut ; the fruit is then put into a large wooden mortar, or ‘Canong, 
and worked about with a pestle until the pericarp is separated from 
the shell. 
“9nd, Pericarp is then put into another pot of water and boiled 
until the oil comes to the surface of the water and the fibre sinks to 
the bottom. 
“3rd, The oil is then separated from the water and is fit for 
process and the machines which have been invented do not appear 
to give very satisfactory results, owing to th 
spherical, passing through them uncracked. In the Gold Coast 
two machines have been tried by the Government ; in the case of 
one machine (Gwira), after an experiment with 38 Ibs. of dried nuts, 
26 Ibs. or 68°42 per cent. remained unbroken and 3} Ibs. of kernels 
were obtained; on passing the 26 Ibs. again through the machine 
14} Ibs. of nuts remained unbroken. The other machine (Miller) 
appears to be somewhat more satisfactory for, after a trial with 2,050 
nuts, 392 or 19°12 per cent. remained unbroken. The cost of 
process. Since estimating labour at ls. per day it would cost 
£1 33. 6d. to produce 379 lbs. of kernels—the amount yielded by 
the machine—valued in the local market at 16s. From ls. to 3s. 
must be deducted from this amount to pay for transport to place 
the kernels on the local market (Evans). / 
It is suggested by Evans that the cost of separating kernels and 
hulls could be considerably reduced by having @ tank ints filled 
with salt water placed by the machine to catch the kernels and 
hulls as they fall out, as the kernels would float. 
An ‘account of the Miller machine was given 1 the Annual 
Report upon the Agricultural Department for 1903, and the 
following table quoted by Evans is taken from that report. 
«The cost of labour in connection with passing 2,050 Ibs. of nuts 
through the machine was 1s. 6d., and picking out the kernels 
£1 12s,
