grassy plains take their place. This process can be seen on any 
island of the Philippines in all its stages. In some places the 
people are trying to overcome the cogon with the poor Chinese 
plows and the buffalo, but it is a slow way, and most of them 
prefer to move on to the fofests again. By this means the central 
islands, which are the most thickly peopled, have become for the 
most part covered with grass, while the more sparsely settled islands 
of the west and south remain in forest.
