 out one great track of the migrant swarm with much precision, and 

 that a second may be laid out with considerable probability.

 have left any trace are those of the earlier Proto-Samoan swarm, 

 and that the wanderings of the later Tongafiti migration must be 

 sought elsewhere than in Melanesia.
