seven million sterling. The output of tin from Perak ranged between 18,960 tons, valued at $23,099,506 in 1899, and 26,600 tons, valued at $35,500,000, in 1905. The fluctuating character of the output was due to the uncertainty of the labour supply. The mining population was recruited exclusively from the districts of southern China, and during certain years an increased demand for labourers in China itself, in French Indo-China, in the Dutch colonies, and in South Africa temporarily and adversely affected immigration to the Straits of Malacca. The output had, moreover, been affected from time to time by the price of tin, which was $32.20 per pikul in 1896, rose to $42.96 in 1898, to $74.15 in 1900, and averaged $80.60 in 1905. Exclusive of tin, the principal exports were $108,000 worth of Para rubber, $181,000 of copra, $54,000 of hides, $48,000 of patchouli, and considerable quantities of timber, rattans and other jungle produce. Negeri Sembilan The revenue of the Negri Sembilan amounted to only $223,435 in 1888. In 1898 it had increased to $701,334, in 1900 to $1,251,366, and in 1905 to $2,335,534. The revenue for 1905 was derived mainly as follows: – customs $1,268,602, land revenue $145,475, land sales $21,407, while the revenue farms contributed $584,459. The expenditure in 1905 amounted to $2,214,093, of which $1,125,355 was expended upon public works. The trade returns for 1905, which are not, however, complete, showed an aggregate value of about $13,000,000. The value of the tin exported during 1905 exceeded $6,900,000, and the value of the agricultural produce, of which gambier represented $211,000 and damar $80,000, amounted to $407,990. Pahang The revenue of Pahang in 1899 amounted to only $62,077; in 1900 to $419,150. In 1905 it was $528,368. The expenditure in 1905 amounted to $1,208,176. Of this sum $736,886 was expended on public works. Pahang is still a source of expense to the federation, its progress having been retarded by the disturbances which lasted from December 1891 until 1895, with short intervals of peace, but the revenue was steadily increasing, and the ultimate financial success of the state is considered to be secure. Pahang owed something over $3,966,500 to Selangor and $1,175,000 to Perak, which had financed it for some years out of surplus revenue. The value of the imports in 1905 was $1,344,346, that of the exports was $3,838,928, thus making a total trade value of $5,183,274. The most valuable
