76 HINTS TO TRAVELLERS. 



The nests of the wild pigs, made of small boughs and twigs 

 bitten off by the sows, often seen in the jungle, are also infested 

 with noxious insects. 



Land leeches of two varieties abound in the forest. The 

 variety with a yellow stripe down the side inflicts the most 

 painful bite, and a sore once caused by it is not healed without 

 much trouble. If you sit down in the jungle for a few minutes 

 and observe, you will see the leaves in motion all about your 

 neighbourhood, and soon will discover that numberless leeches 

 are making their way towards you. I have sometimes on halt- 

 ing taken off as many as twenty from each foot when I have 

 not troubled to remove them whilst on the march. Never pull 

 the leeches off, if you can help it, as they take with them a 

 piece of skin ; but squeeze some tobacco juice on them, and 

 they Avill immediately fall away. 



Bridges are easilv constructed, either by felling trees or by 

 tying bamboos across the river. If a river is so broad and deep 

 as to be unfordable, get one of the party to swim across with an 

 axe ' biliong,' and then fell a big tree on either side, selecting 

 those about 130 feet in height, and taking care to make them 

 fall up stream. The branches of the two trees will be locked 

 together by the force of the current, and you can then walk 

 down the trunk of one, cut your passage through the branches, 

 and up the trunk of the other. Always take a * biliong ' with 

 you, as it is a most useful tool. 



Make-shift boats, called by the Dyaks ' utap,' may be very 

 c|uickly constructed of the bark of a tree.
