There are several kinds of crocodiles, broad and long snouted. In the Perak Museum is a specimen nearly twenty-five feet in length, but the longest that has been caught in Sarawak, and authentically measured, was nineteen feet. The Government gives a reward for killing these pests, which is paid upon some 250 to 300 annually brought to the police station at Kuching. More are killed in the various districts of which no record is kept. Sharks of several species abound, but cases of injury by these are very rare. Saw-fish are also common, and with their long spiny saws are dangerous creatures. A fisherman was killed by one of these at the mouth of the Sadong; he was in a small canoe when the fish, which he had cut at with his knife, struck him a blow on his neck with its saw, from which he died almost immediately. Excellent fish are abundant, such as mackerel and herring, considerably larger than the English varieties, pomfret, barbel, soles, mullets, etc., and some of beautiful colours; also crabs, prawns, and oysters. The dugong (Malay duyong), the sea-cow, is rare in Sarawak, but common in North Borneo, as is also the whale; in Sarawak the latter are occasionally stranded on the beach. Turtles abound; these are preserved for the sake of their eggs, which are considered a great delicacy. We will now consider the races that occupy Sarawak territory; and the following brief ethnological notes with regard to those of Indonesian stock will be all that is necessary for the purposes of this book; to attempt anything like an accurate classification of the many tribes and sub-tribes which differentiate the heterogeneous population of the country would be beyond its scope, even were it possible to trace the divergence of the cognate tribes from the original stock, and of the sub-tribes from the tribes. That there may have been earlier inhabitants of Borneo than those now existing in the island is possible. Traces of neolithic man have been found, but these may be due to the first settlers having brought with them stone weapons cherished as charms. Of paleolithic man not a trace has been discovered.[17] To attempt to determine the flow of mankind into the country, or to decide which of the tribes of Indonesian stock now found in Sarawak was the first to occupy the soil, is to undertake an impossible task.[18] It may be accepted that the most barbarous peoples, the Ukits, Bukitans, Punans, and other fast vanishing tribes, were the earliest inhabitants of whom we know anything, and that they were immigrants. But whence they came we know not. These tribes are all more or less related in language and customs, and in Borneo difference in names does not always denote any essential racial distinction.
