When the family goes up to the river , they take the dogs with them. Them is a mistake because when they see a herd of buffaloes, the dogs start barking. The boys have to shoot down one of the buffaloes because the family are at risk of being attacked.
they catch two young buffaloes. this is good because the buffaloes will give them and pull the plough.
In winter, life on the island is very difficult. The rain never stops and the family are always wet. The tree house they built is no longer as comfortable as before and there is little food left so they have to kill a few of their animals. The family have a very bad time.
